270 winchester vs 308

You will find the bullet weights of .308 cartridges to fall between 125 and 170 grain with a few outliers in both directions. When looking at the .270 vs .308, it’s difficult to draw a firm conclusion on which is the better cartridge. 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. 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). You’ll feel the kick with both of them, essentially. Based on their hunting use, we don’t see any real difference in price between the two. We do know that there is a lot of variance between the individual rounds, but the top performing rounds in this category are .270 Win factory loads. Higher velocity certainly means higher KE and flatter shooting, but it doesn’t guarantee penetration. Bullet’s with the same momentum and same mass but different sectional densities will have different penetration results. There isn’t a very significant difference between the .270 Winchester and .308 Winchester when it comes to recoil. The chart below compares how much a 10 mile per hour crosswind impacts those same four loads out to 500 yards.Once again we see that the .308 Winchester load outperforms the .270 Winchester when using 150gr bullets, but the 130gr .270 load has far less wind drift than either .308 load. Though there is quite a bit of overlap in barrel lengths, .270 rifles often have slightly longer barrels than .308 rifles. As we come to a close with this comparison, we want to bring all the information we have examined and use it to start trying to figure out if there are scenarios where one cartridge might be better suited than the other, or maybe applications where you can’t really go wrong with either of them. For hunters and competition shooters alike, the trajectory of a round is characteristic that garners a lot of attention and scrutiny. By the same token, the .270 has taken untold numbers of moose, elk and plains game without any issues. There are several components to stopping power of a particular cartridge. C'est même un des pire. For the muzzle velocity, we used the data provided by the manufacturer so take that with a grain of salt as well. The data used to compare the trajectory and wind drift of the cartridges was obtained from Federal. You don’t want to spend the night tracking through the woods after an injured animal because the bullet didn’t have enough power to drop it cleanly. My shots rarely exceeded 125 yards or so in the foothill country that I hunted in central Wyoming. 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). Heavier, more stoutly-constructed bullets are almost universally better at penetration, given their lower velocities. At a MV of around 2600 fps, nearly all bullets will perform reasonably well, both ballistically and, more importantly, terminally out to 200 or 250 yards. Make sure you follow The Big Game Hunting Blog on Facebook, Instagram, Twitter, and YouTube. The .270 Winchester and .30-06 Springfield are two of the most popular cartridges for hunters in the United States. 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. As you can see in the photo below, the .270 Winchester and .308 Winchester cartridges have very different external dimensions. The .270 Winchester has a significantly longer case length (2.54″ vs 2.015″) as well as overall length (3.34″ vs 2.81″). For several years, the .270 did not have a significant following of users. So while this method for comparing the .270 vs .308 is cleaner, all of these different aspects should be taken together to give you an idea of which cartridge is going to be better suited for specific applications. I think the majority of hunters and shooters would agree that the .270 Winchester and .308 Winchester are outstanding hunting cartridges. 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. 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. Let’s take a look at the average SDs for our larger data set. Buy a great .270 Winchester hunting rifle here. Pour les bêtes que l'ont chasse au Québec. 4. penetration. Go. If you know the hunting you want to take part in, this article will make your decision easier. Still, for the sake of being thorough, we wanted to see how the two compare in this category. And there is a reason that sectional density is not used as the sole metric to determine potential penetration. for longer range better go for the 7mm Rem Mag or 300 Win Mag/300 Wby Mag with 180gr. 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. These diameters play a role in the weight of the bullets that are used by the two cartridges and in other performance specs that we will look at later in the article. For other readers: you can see what Brian is talking about with regards to the 270 Winchester vs the 280 Remington at the link below. So, let’s take a look at the ballistic coefficients of the ten rounds we are comparing (Graph 4). Since the .308 Winchester is essentially a scaled down .30-06, with the exception of recoil (which we’ll get to in a minute) the .270 Winchester has the same advantages over the .308 as it does over the .30-06. Therefore, I rule out using the .308 for moose because I think a 165 grain bullet is too light for an animal that size unless you have the velocity created by the .270 Win. 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. Just from looking at the casing and overall cartridge specs we can begin to garner some information about the .270 vs .308. Since both the 150gr loads have virtually the same muzzle velocity, the primary reason the .270 has more wind drift is because the .308 bullet has a significantly higher ballistic coefficient. Dans ces deux derniers cas, je préfère de loin une 223Rem. This round is a bit more expensive compared to the other .270 factory loads that we have looked at, but it gives you the best long-range performance. These numbers are not going to tell you how deep a bullet will penetrate. While there are a few technical differences between the two, most refer to them simply as “the 308.” If you’re familiar with historic battle rifles like the M14, H&K G3, FN FAL or the M60 machine gun, then you’r… For shots taken at extended ranges, a higher BC often means fewer adjustments will have to be made to get the bullet on target. 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). They named this round the .223 Remington and paired it … Of course, these are just averages and there are definitely .308 rounds that perform above the average. For general long-range shooting, a lot of the above discussion is pertinent here as well. To be a great hunter, you might need to turn to more than one cartridge on your adventures. 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. Using a .277-inch diameter bullet and the case length of the .30-03, the .270 Winchester gave high velocities and a flat trajectory. Bullet momentum is another factor that goes into stopping power and is always involved in the arguments for the best indicator for stopping power. In this hunter’s opinion, 175 gr 280 Rem and 180 gr 308W hit a sweet spot in bullet performance. The .270 Win, on average, has less bullet drop than the .308 Win. You will often see the loose guidelines for how much energy is needed to harvest specific animals. Not surprisingly, the .30-06 Springfield was an almost instant success in the civilian market. The Federal Vital-Shok Nosler Partition 150gr is one of our favorite hunting rounds for the .270 cartridge. The original .270 Winchester load shot a 130 grain bullet at a velocity of 3,140 feet per second (2,846 ft-lbs of energy). Both of these have a history in long-range performance in an assortment of 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. With regards to bullet selection, .308″ bullets in particular are very easy to find. 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. 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. So I bought a Glenfield carbine in 30-30 and fitted it with a 2-7X scope. There is a lot of overlap between the two cartridges with both of them having rounds that carry a significantly more amount of energy while others fall behind. While 2900 fps sounds cool and all, a high impact velocity means the bullet will almost certainly fragment on impact when using lower-end bullets. The general trend of the long-range data between these two cartridges is very similar to what we saw with the short range trajectory. For target shooting, knock yourself out and take both to the range and have a ball. .308 Winchester vs. 7.62×51mm NATO. This fits with the original intent of the designers interested in building a mild shooting and easy to handle cartridge that was still powerful enough for hunting medium sized game at short to moderate range. However, the .308 performs better with heavier bullets than the .270 and is available in a wider range of bullet weights and models. Other factors such as velocity and bullet design also play a role in penetration, but we will mostly keep the conversation on sectional density. Recovery of the animal is a must. From the averages above, we see that the .270 Win rounds stay at supersonic speeds for about 80 yards further than the .308 Win rounds. The fact that the .270 and .308 each have very devoted fan clubs can also make it difficult to navigate the debate. With both cartridges excelling slightly at different categories, we don’t think there is really much of a difference in how well the two will penetrate from the standpoint of these numbers. But I’d opt for something of stouter construction for a 130 gr 270, which means a bit more expensive. This is another excellent option for medium to larger game. For the most part, we see a lot of the same results with the larger data set. The first is that these numbers are not set in stone. 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. Cartridge and bullet design give it a lot of versatility, and it is also readily available. This was due to a number of reasons, one of which was the fact that the .270 Winchester fired unusual size bullets. But, even then I think the hunter is on a very thin edge of killing efficacy. Neither of the cartridges, though, has a recoil that might make you … Make 260 Remington vs. 308 Test Fair. An Overview Of 6.5 Creedmoor Vs. 270 270 Winchester. When used in the right scenario, both the .270 and .308 are effective cartridges for bringing home game or smoking the competition on the range. For large game at increased distances, the .308 is just harder to put on target in the kill zone.
