While the .270 had a very high muzzle velocity compared to other popular cartridges of the day, it was not an instant commercial success. With two decades of chasing all manner of upland game, hooved mammals, strutting gobblers, and any small game that can fit in his Dutch oven, he hopes to offer new ideas and viewpoints on hunting and firearm concepts and traditions. The .270 Winchester was introduced in 1925 where it would stay in relative obscurity for a time. For now, let’s jump into these ballistic categories. Though some were reluctant to adopt the cartridge, many American hunters eventually came to appreciate the flat shooting characteristics of the round as well as the fact that it was so effective on thin skinned game. It is more clear at this range where the rounds for each cartridge begin to group. It’s a new world out there. Néanmoins, cette munition est peu adaptée aux gibiers de très grande taille. This round has nearly 2,000ft.s velocity at 500 yards which is more than enough to get the correct terminal ballistics. Still, looking at the actual energy still gives you a lot of valuable information and it loosely correlated to felt recoil. 270 vs 30-06: Ammunition Selection. When we look at these numbers, we are addressing how well a bullet is able to stay in motion when faced with resistance. You will often see the loose guidelines for how much energy is needed to harvest specific animals. 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. For those reasons, understanding their true strengths and weaknesses can be pretty confusing at times. So, in regards to the .270 vs .308 debate, let’s look at some of these applications. It’s a great medium to large game rifle and can be used for just about any large game animal in the world, barring a few. The .270 Winchester is a very flat shooting and moderately powerful cartridge, especially considering that it’s nearly 100 years old. I think the majority of hunters and shooters would agree that the .270 Winchester and .308 Winchester are outstanding hunting cartridges. Unfortunately, we are limited in our available space and decided to cut the samples off at ten. Within that range, there will be little if any difference in the accuracy of the two based on bullet drop from the .270 v. .308. If you’d like to learn more about the evolution of intermediate cartridges, read the article below. Pour les bêtes que l'ont chasse au Québec. For any round of any cartridge type, you want to see a flat trajectory with minimal bullet drop. Momentum (not KE) is king when it comes to penetration, and heavier bullets retain it better than lighter bullets. Both of these have a history in long-range performance in an assortment of applications. Le .270 Winchester est une cartouche de chasse de calibre 7,04 mm, ne pas se fier à l'indication .270, son diamètre réel est de .277".Selon Le Chasseur français, il convient au chamois, au chevreuil, au cerf et au sanglier.Il est fabriqué industriellement et porte aussi le diminutif de .270 Win.. Il a été créé en 1925 à partir d'une douille de 30-06 sprg. Though the .308 Winchester certainly has an edge over the .270 when shooting 150gr bullets, the 130gr .270 load has more energy remaining and shoots flatter (the .308 has 15-20″ more bullet drop) at 500 yards than both .308 Winchester loads. When looking at the .270 vs .308, we have to examine the long-range trajectory of these cartridges. Using a .277-inch diameter bullet and the case length of the .30-03, the .270 Winchester gave high velocities and a flat trajectory. Both cartridges have a tremendous amount of energy at the shorter distances, over 2,500ft.lb average muzzle energy for both. The first is that these numbers are not set in stone. Ballistic data for the original 7.62x51mm military cartridge was obtained from Inetres. C'est même un des pire. As we’ll discuss in a minute, this is partly due to the widespread use of the .308 Winchester (and other .30 caliber cartridges like the .30-06, .300 Win Mag, .300 Ultra Mag, and 300 PRC) in long distance shooting competitions. Do you primarily hunt deer sized game (including black bear) at ranges less than 200 yards? While the differences are not too dramatic between these two cartridges, we still see the trend of the .270 Win having a flatter trajectory than the .308 Win. The faster 150 grain bullets were tried for mule deer but I was disappointed with the significant meat damage. The .270 Winchester came along in 1925, released in the Winchester Model 54 rifle. The reason for this is the smaller diameter of the .270 allows more force to be localized to a smaller area and helps push the bullet deeper. We will also take a look at other categories such as recoil, accuracy, and availability of the ammunition. This difference in trajectory widens slightly as the bullets move out to the 300-yard mark. Note: there is quite a bit of overlap with the performance of various 150 grain loads for both the .270 Winchester and .308 Winchester. 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. Le calibre 270 winchester, apparu en 1925, est un calibre qui offre beaucoup de polyvalence avec sa trajectoire tendue et sa puissance d'un bon niveau. On the other hand, the .308 Winchester is relatively common in semi-automatic sporting rifles like the AR-10 and M1A. If you begin picking out individual rounds, you can find some huge differences between .270 and .308 rounds where the .308 round shows between fifteen and twenty more inches of bullet drop. Do you hunt in areas where it might be necessary to take a longer range shot? It is important to note that what we are comparing here is straight recoil energy. And receive our newsletter with the best articles covering guides, guns & gear. We selected a round from each cartridge that are from the same manufacturer, have the same bullet design, are of similar bullet weights, and have similar ballistic coefficients (Graph 5). For instance, the 150gr Nosler Partition below really did a number on a big kudu bull in South Africa. It’s really just a matter of each cartridge having certain strengths and weaknesses. Both are very common in bolt-action rifles. Virtually every major style of bullet is available in .270 and .308 as well like the Barnes TTSX, the Hornady ELD-X, GMX, InterBond, InterLock, SST, and V-Max, the Nosler AccuBond, AccuBond Long Range, Ballistic Tip, E-Tip, and Partition, the Remington Core Lokt, the Swift Scirocco and A-Frame, and the Winchester Power Point (just to name a few). 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. Home defense or hunting, small or big game, short or long distance are only a few options that you have to think about. 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. And as we state in just about every category, this doesn’t mean there are not .308 factory loads out there that will perform above the average, but it might be hard to find a factory load that can match the average of the .270 at 500+ yards. As illustrated in the chart,.270 Winchester rounds - on average - achieve a velocity of about 3060 feet per second (fps) while.30-30 Winchester rounds travel at a velocity of 2370 fps. The rounds of each cartridge do group together pretty tightly until they get out to the 500 yard marker. Excepting 375 H&H and 375 Ruger, there’s a reason dangerous games cartridges aren’t generally any faster than about 2200-2300 fps. And as we have stated several at several points, it’s not that we are saying it is impossible, we are just saying that the ballistics lean towards the .270 in this situation. The general trend of the long-range data between these two cartridges is very similar to what we saw with the short range trajectory. These projectiles quite often take advantage of the latest developments in bullet development and offer advantages in precision and ballistic coefficient compared to the bullets used by the .270. By necking down the .30-06 case to shoot smaller diameter bullets, the designers of the .270 Winchester built a cartridge with a higher velocity, flatter trajectory, and less recoil than the .30-06 Springfield. At least around here, when wallyworld puts their fall sales on ammo, its usually centered around the 30-06 and 308. Let’s take a look at the recoil numbers with more rounds added to the group and see if the same results present themselves. The .270 Winchester has a significantly longer case length (2.54″ vs 2.015″) as well as overall length (3.34″ vs 2.81″). By the same token, the .270 has taken untold numbers of moose, elk and plains game without any issues. Our objective is not to name one cartridge as being better than the other. Are you just itching to take a rifle chambered in one of these cartridges on a hunt? For the most part, we see a lot of the same results with the larger data set. We have calculated the bullet momentum for our ten selected rounds and graphed them below from the muzzle out to 500 yards (Graph 10). Smaller diameter bullet is going to penetrate deeper because less resistance is encountered. 1. price Of course, with different types of rounds for these two cartridges, there will be certain rounds that might be more significantly different. 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. All that being said, while the .308 probably has a slight edge here, both cartridges have the potential for excellent accuracy in the right hands. 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. Not always a fantastic component bullet For that reason, users of the .308 Winchester benefit from the extensive the research and development that has gone into refining .308″ bullets and rifles for long range shooting in the United States over the last century. Pour les bêtes que l'on chasse au Québec. la 30-06 a plus de force d'impact(???? There are high and low BC rounds for both the .308 Win and the .270 Win. 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 rate at which both cartridges bleed velocity doesn’t seem to be significant. Buy some great .308 Winchester hunting ammo here. With a leap in bullet technology, the .270 is much better suited for taking larger game such as elk. As for price, it can vary pretty wildly depending on the make of the ammunition. 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. While less than an inch difference at 200 yards, nearly four inches at 300 yards, and a little more than five inches at 400 yards, might not seem like much, it can easily be the difference between success and failure. 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. Additionally, the Browning X-Bolt, Kimber Hunter, Mossberg Patriot, Nosler Liberty, Ruger American, Ruger Hawkeye, Savage Axis, Thompson Center Compass, Tikka T3, and Weatherby Vanguard are available in both calibers. The 150gr .270 round shows a higher sectional density and depending on the bullet type, better penetration than the 150gr .308 rounds. There is quite a lot to talk about after looking at the graph. Recovery of the animal is a must. And again, we realize the possible errors and the biases that come with using a small sample size. Pros: Better performance at medium ranges. This is just due to the availability of lighter grain bullets. 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. Besides, with that adrenaline pumping, you’re not going to feel it anyway. At this distance, the average drop of the .270 rounds is 11.6 inches while the average drop of the .308 rounds is 14.68 inches. While each cartridge offers certain benefits to hunters, there is also a pretty big overlap in their capabilities. Receive our newsletter with the best articles covering guides, guns & gear. Cartouche de chasse; Ruag Ammotec; le 4 août 2017. We will take a look at the history and specifications of these cartridges as well as look in detail at the ballistic categories. The data used to compare the trajectory and wind drift of the cartridges was obtained from Federal. The .270 Winchester and .30-06 Springfield are two of the most popular cartridges for hunters in the United States. Both cartridges tend to bleed energy at the same rate as they move down range as the differences between the averages remain within 50ft.lbs of energy throughout the 500 yards. But I’d opt for something of stouter construction for a 130 gr 270, which means a bit more expensive. It’s a good example of how bullet design is the driving factor in this category. Before we wrap up this article, we want to re-examine the ten rounds we have been comparing and pick a round from each cartridge that we think will excel in certain situations. 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. There are some .308 rounds out there that perform well at these distances as well, but generally, the .270 would be the better choice. This was due to a number of reasons, one of which was the fact that the .270 Winchester fired unusual size bullets. Before we discuss any differences and trends that we see between the .270 vs .308 in sectional density we want to take a look at two rounds of the different cartridges that share the same bullet weight to show how sectional density can differ based on the variables that go into calculating the sectional density. With regards to bullet selection, .308″ bullets in particular are very easy to find. You can see that the .270 is a much longer and skinnier cartridge than the .308. Where calculations are made, we will be sure to make clear our variables. 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. So I bought a Glenfield carbine in 30-30 and fitted it with a 2-7X scope. 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. While the .308 produces slightly more recoil energy (21.7ft.lb compared to 19.6ft.lb), it probably isn’t anything significant, especially to more experienced shooters. 223/5.56 vs 7.62×39: Everything You Need To Know. Before we get started, I have an administrative note: Some of the links below are affiliate links. 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. The same goes for the BCs of these rounds. Another important concept to take away from this graph is that all of these rounds remain supersonic all the way out to 500 yards and if we were to extend this range we would see this trend continue for several hundred more yards. However, that makes sense when you consider that the .308 and .270 were designed as lower recoiling alternatives to the .30-06. Each gun has its own unique qualities that are going to influence the numbers. You will find the bullet weights of .308 cartridges to fall between 125 and 170 grain with a few outliers in both directions. This is only a preference, not a requirement for me. This round is affordable which is an important consideration when you plan burning through quite a few out on the range. The Glenfield 30-30 is my main rifle for deer and wild hogs. Especially when using a heavy bullet (180+ grains), the .308 has a significant advantage when hunting most plains game in Africa like blue wildebeest, kudu, and eland. An Overview Of 6.5 Creedmoor Vs. 270 270 Winchester. Eventually, I wanted to go after elk but wanted to remain with a lever action so in 1972 I bought a Savage 99 in .308 shooting 180 grain core-lokt ammo.
