The.270 Win HAS less bullet, "Drop" (Flatter Trajectory) than the.308 and with, a 140 grain Nosler AccuBond or, partition, starting at 3,000 FPS, should be an efficient "Elk slayer" to about, 500 yards ! We see this the most at the 400 and 500 yard marker where the .308 Win only has about 17 more ft.lbs of KE and then less KE than the .270 Win rounds at the 500 yard mark. The Federal Vital-Shok Nosler Partition 150gr is one of our favorite hunting rounds for the .270 cartridge. Momentum (not KE) is king when it comes to penetration, and heavier bullets retain it better than lighter bullets. So, in regards to the .270 vs .308 debate, let’s look at some of these applications. By the time the rounds reach the 300 yard mark, there is only 4lb/ft.s of momentum difference between the rounds of the different cartridges. Like all the other categories there are some .308 rounds that are similar, but there are several .270 rounds that outperform all of the .308 rounds we have looked at. For those who are more interested in long-range shooting, this section might not carry the weight the ballistics section has. Each gun has its own unique qualities that are going to influence the numbers. You’ll feel the kick with both of them, essentially. The data used to compare the trajectory and wind drift of the cartridges was obtained from Federal. The .308 shows certain performance capabilities, which we will get into in this article, that has given it a place in many sharpshooting capacities, including use with the police and some military forces. There are smaller weights that are available for small game. With a degree in Microbiology and several years of doctoral work manipulating bacterial genes, he attempts to merge the rational and unbiased thinking of scientific research with the passions of hunting and fishing. Those same characteristics also make it a very good choice for mountain goat in Canada or Himalayan Tahr and chamois whileÂ hunting in New Zealand. The .308 Winchester/.308 Win/.308 was introduced in 1952 in the United States. The fact that the .270 and .308 each have very devoted fan clubs can also make it difficult to navigate the debate. Get our PDF with 13 pistol & rifle targets (worth $48) including expert instructions for FREE! While it appears that the .270 has rounds with a distinct advantage in long-range trajectory, there are .308 rounds that are more than capable of being used at these ranges. My shots rarely exceeded 125 yards or so in the foothill country that I hunted in central Wyoming. In this hunter’s opinion, 175 gr 280 Rem and 180 gr 308W hit a sweet spot in bullet performance. The military developed it as a small-caliber, high-velocity round for NATO forces. You can find a case of .308 for twenty bucks and a box down the aisle might be forty dollars. For large game at increased distances, the .308 is just harder to put on target in the kill zone. The cartridge is the same length as the .280 Remington, both of which are longer than the .30-06 Springfield.The .270, .280, and .30-06 were all derived from the .30-03 parent case. We already know that the .270 Win rounds have a smaller diameter than the .30 cal cartridge and when we added in more rounds, they contained quite a few heavier rounds that bumped up the average. For target shooting, knock yourself out and take both to the range and have a ball. In my opinion the 180 grainer bullet is too heavy for the smaller powder capacity for the shorter cartridge. This is because the smaller diameter .270 Winchester shoots lighter bullets than the .308 and the .30-06. Regarding recoil, we have seen that both cartridges generate a similar amount of energy, so we don’t think that distinguishes either of the two cartridges regarding accuracy. While we agree that energy is important, we also think shot placement is as important if not more. The bullet energy is the highest of the selected .308 rounds with 1,300ft.lbs of energy at the 500-yard mark which is enough for even larger game at that range. If I was just game hunting though I would get the 270 for … While the .270 had a very high muzzle velocity compared to other popular cartridges of the day, it was not an instant commercial success. Case capacities for the .270 Win and .308 Win were obtained fromÂ Nosler. All of the .308 rounds do show a slight increase in recoil energy than the .270 rounds, but again, we don’t think these differences are enough to enough to choose one cartridge over the other based on recoil. I moved away from Wyoming and settled here along the Gulf Coast of Florida where deer are much smaller. If you fired these rounds from your platform, you would more than likely you’re going to see numbers that vary from what you will find here. Let’s move on and look at a second metric for this category. There are several .308 Win rounds that break the 1000 yard mark, but much less often when compared to the .270 Win. la 30-06 a plus de force d'impact(???? The same goes for the BCs of these rounds. 130s have certainly proven their lethality over time, but I’m primarily a meat hunter, and I’ve been less than pleased with what 150 gr 308 does to meat. Jack O’Connor, a famous writer of firearms and hunting, really pushed this cartridge and its abilities in the field and brought it to the forefront of hunting cartridges, where it remains to this day. We took some liberties in making this graph. With a significantly flatter trajectory and more resistance to wind, the cartridge does very well on longer shots, particuarly on thin skinned game like mule deer, pronghorn, sheep, or tahr. Though we will look at each of these categories separate from the other, in reality, all of them influence and play off of one another. We have seen the flatter trajectory of the .270 versus the .308, and that may play a role in it being more accurate, especially at ranges over 300 yards. The .308, as the name implies, has a 30 cal bullet with a .308″ diameter bullet. The 243 is … Create more recoil by 15% than the 6.5 version. How we will compare penetration of these two rounds is to look at the sectional densities (SD) of the bullets as it allows us to look at the two cartridges rather than the differences between bullet styles. It’s a new world out there. And again, we realize the possible errors and the biases that come with using a small sample size. For the .308 rounds, it has one of the best long-range trajectories where a 300-yard shot is no problem in the right hands, and 400 yards is even manageable. Smaller diameter bullet is going to penetrate deeper because less resistance is encountered. In summary, I had very good luck with my .308 downing elk and a couple bears but it’s too powerful for common deer at typical distances hunting the forests and foothills. Receive our newsletter with the best articles covering guides, guns & gear. Cons: Lengthy action and heavier gun. However, the folks at Winchester went the opposite route and necked down the .30-06 to use .277″ instead of .308″ bullets. If we take the average of the given rounds, we see that the .270 has a slight advantage with only a hundredth of a difference. I used the Federal Ballistic calculator and ShootersCalculator.com to compare wind drift, the range each bullet goes subsonic, and recoil for the cartridges. Both the .270 and .308 will work extremely well under those conditions and there is very little difference between them at short range. With proper shot placement, this round still has the energy and the velocity to make a clean kill. Obviously, just from this little bit of information, we can already guess that the two cartridges are going to show some differences in their ballistics and other We will see how these specifications influence the ballistic and other properties of the cartridges shortly. On the other hand, even though the 180gr .308 bullet weighs more and has a slightly higher BC than the 130gr .270 bullet, the .270 has an additional 490fps of muzzle velocity that translates into a significantly flatter trajectory and less wind drift. Both cartridges are capable of outstanding accuracy, but the .270 Winchester is used almost exclusively as a hunting cartridge. Let’s see if the higher muzzle velocities of the .270 Win rounds holds up when we add more rounds to the group. Specifically, the military wanted a new rifle chambered in an intermediate cartridge, capable of automatic fire, and equipped with a detachable magazine. Let’s take a look at the averages of our larger sample size and see if the same trend persists. Im not suggesting blasting off a perfectly beautiful bluing job in exchange for cerakote but if its got some worn bluing and is not a collectible that may be an option. There are some trends between cartridge types though. The .270, on average, has higher velocities than the .308 which a lot of long-range shooters will be key on. The .270 is fitted with a .277″ diameter bullet. The long range trajectory for this round is not as flat as other .270 rounds but it is still manageable at 400 yards and to be honest, any range after that we are not concerned with when it comes to hunting. Néanmoins, cette munition est peu adaptée aux gibiers de très grande taille. In this table, we have actually extended the range out to a 700 and 1,000 yard marker. The same can go for the .270. An Overview Of 6.5 Creedmoor Vs. 270 270 Winchester. Indeed, they’re both consistently among the most popular centerfire rifle cartridges used in the United States each year for good reason. If we look at our comparison of the ten different rounds we have used we can see some general trends (Graph 3). If we step back and look at the two cartridges, we see some pretty interesting results. Though the differences are slight overall, we can pick out certain rounds where there is a 4 or 5ft.lb increase in recoil energy from a .270 to .308 round. What is a little different now that we have more rounds is that the rate at which the .308 Win rounds bleed KE is a little steeper than the .270 Win rounds. Given the .270 Winchester’s case capacity and its later success with H-4831, which is the slowest-burning powder of those mentioned, it would seem logical that the best combination in the years before H-4831 became available would have come with either IMR-4350 or 4320. Like many other cartridges developed in the United States, the story of the .270 and .308 Winchester begins with the .30-06 Springfield. The “felt recoil” involves a lot more factors than just the type of cartridge used. Even so, the .270 Winchester has significantly more case capacity due to the much longer case used by the cartridge.Finally, the .270 Winchester has a slightly higher maximum average pressure authorized by SAAMI cartridges (65,000psi vs 62,000psi for the .308 Win). Remington made a great cartridge in the 280, but really botched the rollout and the cartridge has never recovered. Thanks Brian. While a gun and the ammunition may be capable of sub-MOA accuracy, real-life hunting is not like shooting on a shooting stand. Table below compares the four different Federal Non-Typical Whitetail loads: 130gr (.372 BC) and 150gr (.261 BC) loads in .270 Winchester and 150gr (.313 BC) and 180gr (.382 BC) loads in .308 Winchester. Providing approximately 90% of the power of the .30-06 in a smaller package, the cartridge soon became very popular and is now one of the most widely used big game hunting rounds in North America. The .270 Win, on average, has less bullet drop than the .308 Win. It’s difficult to pick an accuracy winner between the 270 vs 308 though because it’s something of an apples to oranges comparison. But, before we take that to the bank, let’s see if those trends hold up when we take a look at a larger sample of rounds for these cartridges. Pas de choix de grain (130-140-150Gr), Vitesse ultra trop vite pour la chasse de proche, certain s'en servent pour toute les chasses, même le Coyote et la Marmotte. From this graph, we see that there is no noticeable difference between the two rounds to the 200-yard mark. I would suggest reconsidering the need for long-range hunting (above 400 m / 450 yards). The .270 Winchester came along in 1925, released in the Winchester Model 54 rifle. So, let’s take a look at the ballistic coefficients of the ten rounds we are comparing (Graph 4). However, the .308 has a slightly steeper shoulder angle (20 degrees vs 17.5 degrees). Make sure you follow The Big Game Hunting Blog on Facebook, Instagram, Twitter, andÂ YouTube. We’ll start with the .308 Winchester. For most medium size game, 1,000ft.lbs of energy is the recommended amount, and this increases the larger the animal gets. Buy an excellent .308 Winchester hunting rifle here. And if you go back and look at the differences in bullet drop at long ranges you will see that there are .308 rounds that are more than capable of 400 and 500-yard shots. It is more clear at this range where the rounds for each cartridge begin to group. You can see that the .270 is a much longer and skinnier cartridge than the .308. Do you hunt in areas where it might be necessary to take a longer range shot? Bullet momentum is another factor that goes into stopping power and is always involved in the arguments for the best indicator for stopping power. The recoil of a cartridge is going to be important to a lot of shooters, especially those with not a lot of shooting experience. This round excels in the velocity category with over 2,200ft.sec at 500 yards and will remain supersonic for several hundred yards beyond that mark. Though only a few cartridges use .277″ bullets, the .270 is extremely popular and there’s a plethora of quality bullets to choose from. This is also an example of how bringing in more rounds might give us a clearer picture. If you look at the individual rounds (not shown) you would see a lot of overlap between these cartridges around the 20ft.lb area. The 7.62x51mm NATO had virtually the same ballistics as the original .30-06 Springfield load (150 grain bullet at 2,700 feet per second) and also fired a .308″ bullet. On the other hand,Â the majority of .270 Winchester factory loads shoot bullets in the 120-150 grain range. This tells us that these rounds are going to have enough velocity for efficient terminal ballistic characteristics. Though the .308 on average has a higher SD here, there are .270 rounds, as we have highlighted, that have similar or better SD numbers. If we simply look at the average recoil energy generated by these two cartridges and given by the ballistic calculator software, we see that the .270 and .308 are very similar (Graph 1). The .270 Winchester was introduced in 1925 where it would stay in relative obscurity for a time. Recovery of the animal is a must. Pas de choix de grain (130-140-150Gr), Vitesse ultra trop vite pour la chasse de proche, certain s'en servent pour toutes les chasses, même le Coyote et la Marmotte. This round is affordable which is an important consideration when you plan burning through quite a few out on the range. 270 is a nice cartridge; however, I think if the 280 Rem had come out at the same time, the 270W would be a footnote in history. On the other hand, since it shoots heavier and larger diameter bullets, the .308 Winchester has a clear advantage when hunting larger species moose, elk, and caribou. Pros: Better performance at medium ranges. These two cartridges are the .308 and .270. Regardless, from a comparison perspective, computer-generated data is perfect for looking objectively at two cartridges and it removes environmental influences. Not trying to make any ground-breaking statements here, but something occurred to me when I was chrono-ing some loads yesterday, which is that my short-action … Where ballistic calculators are used we kept as many variables the same between rounds of the same cartridge. Both have a bit of a kick, but for hunters and marksman with a little experience it’s nothing you haven’t felt before, and it shouldn’t impact your shot in the field. From this cartridge, the 7.62×51 NATO round was also designed and saw brief use in the US military in Vietnam with the M14 Garand. Just from looking at the casing and overall cartridge specs we can begin to garner some information about the .270 vs .308. Do you primarily hunt deer sized game (including black bear) at ranges less than 200 yards?

For recoil, it’s a wash between these two cartridges. The short-range trajectory is always important to look at. To combat that and provide a little more confidence to the numbers, we have compiled a much larger data set. C'est même un des pire. There has been many moose found that were shot and never recovered by the hunter because of lack of a blood trail, so use what will drop it in its tracks or at least leave a good blood trail. Their omission here does not reflect our attitude towards those rounds. Let’s take a look at the ten rounds we have selected for this article and see if the trend continues (Graph 2). Again, 270 is a fine cartridge, but whatever you shoot, you need to understand that cartridge’s limitations. This round has a great BC for .308 rounds (.45), and when paired with the velocity and long-range trajectory, you have an excellent round for precision shooting. I don't think any struck game animal would notice the difference, but in the 6.5 Creedmoor versus 270 Winchester velocity and energy races, the Winchester still wins.As for the Creedmoor's celebrated ability to resist wind deflection, the superior .625 B.C. Of these, 130 grain and 150 grain bullets are by far the most common. Next Last. With moderate recoil that’s roughly comparable to the .308 and noticeably lighter than the .30-06 Springfield, most shooters and hunters can handle it without much trouble. Aside from the Browning BAR, the .270 Winchester is almost non-existent in semi-automatic rifles. We see the .308 Win rounds carrying on average more momentum than the .270 but as they move downrange, we see the the .270 Win rounds gaining ground. While there are some rounds from each cartridge that are pretty similar in velocity, the trend of the .270 rounds having an average of 200-300ft.sec more velocity than the .308 rounds extends out to the 500-yard mark. Dans ces deux derniers cas, je préfère de loin une 223 Rem. Thread starter ATX762; Start date Jul 21, 2017; 1; 2; Next. We used a common grain powder load for each cartridge type that we determined from Nosler load data as well as assumed that the cartridge was being fired from a 7lb weapon. You will definitely need to take it round by round regardless of the cartridge and pay a lot of attention to how the bullet is going to react on impact. Instead of .284″ bullets like the 7mm Mauser (and more recently developed cartridges like the 7mm-08, .280 Remington, .280 Ackley Improved, and 7mm Remington Magnum), the .270 Winchester used .277″ bullets which undoubtedly hampered adoption of the cartridge to a certain degree. Both are also great for similarly sized game like black bear, feral hogs, javelina, mule deer, and pronghorn as well as exotic game like axis, sika, and fallow deer. I like the 308 over the 270, but if I needed a vary long shot I would go with the 300 win mag. When looking at the .270 vs .308, it’s difficult to draw a firm conclusion on which is the better cartridge. There is some middle ground where the .270 and .308 have rounds that behave very similarly. They named this round the .223 Remington and paired it … We know there are other great rounds that are available and some of these might be rounds you have been using for years. This round was originally brought to be in the form of the 7.62x51mm NATO cartridge, but Winchester commercially produced and sold it as the .308 Winchester. Just take a look at the ten rounds that we have looked at in this article. The relatively light recoil of the cartridge also makes it easier to handle in a lightweight rifle that’s desirable on a mountain hunt. These two numbers are pretty dang similar. We hope that this article has given a clearer understanding of the two cartridges and also made clear that both are tremendous hunting cartridges that are readily available. The .270 is fitted with a .277″ diameter bullet. We also like the heavier grain bullet that can get penetration on larger game. In this section, we will look at several ballistic properties of these two cartridges. Like the short-range trajectory, this data originates from the manufacturer where the zero setting was set at 200 yards and the measurements taken out to 500 yards (Graph 7). Neither of the cartridges, though, has a recoil that might make you … To be a great hunter, you might need to turn to more than one cartridge on your adventures. Make 260 Remington vs. 308 Test Fair. By the 500 yard marker, there is right at 3.5lb/ft.s difference in momentum between the two cartridges. There is something to be said about computer-generated data when it comes to comparing two cartridges. You can see that the .270 is a much longer and skinnier cartridge than the .308. Home defense or hunting, small or big game, short or long distance are only a few options that you have to think about. These numbers do corroborate the trends we saw in our graph. 5.56x45mm NATO, basically the military version of .223, launched in 1961. For our top .308 Win range round we like the 168gr Hornady BTHP Match. The .270 Win is a very efficient round for most hunting, but, if I’m going for moose I want nothing less than the .30-06. C'est même un des pire. 1. price For shots taken at extended ranges, a higher BC often means fewer adjustments will have to be made to get the bullet on target. My solution to this dilemma was to have one of each, (I actually have 2 .308s) in addition to the .30-06. There are definitely more .308 Win rounds above that mark and there are definitely more .270 Win rounds below that mark, as the averages imply. The .270 Winchester/.270 Win/.270 made its appearance in the hunting world in 1925 where it would stay in relative obscurity for a time. Not surprisingly, pretty much every ammunition manufacturer of note like Barnes, Black Hills, Browning,Â Federal Premium, Fiocchi, Hornady, Magtech, Nosler, PMC, PPU,Â Remington, Swift, and WinchesterÂ (just to name a few) produce a wide variety of ammo for both cartridges. Both cartridges have a tremendous amount of energy at the shorter distances, over 2,500ft.lb average muzzle energy for both. Both cartridges have the same .473″ rim diameter. You might have a little better selection of .270 rounds when searching around a retail store than the .308, but generally, you are not going to have an issue finding these rounds and finding various types of ammunition for each. Let’s take a look at the recoil numbers with more rounds added to the group and see if the same results present themselves. vs. 270 WSM March 04, 2019 By Brad Fitzpatrick In 1925 Winchester necked down the .30-03 to .277 and created the .270 Win., a sporting cartridge designed for medium-size game that shot flatter yet recoiled less than the .30-06 Springfield. In this article, we are going to help break down this decision by looking at two cartridges that a lot of hunters will find themselves contemplating which to use. Both cartridges will work, but the .308 Winchester is probably the better choice in this case since it uses larger diameter and heavier bullets that are well suited for very large or tough animals. Prices and availability vary from region to region, but ammunition for both cartridges is widely available.
