7mm vs 270

7mm vs 270

Another factor to consider when deciding on a cartridge is how easy is it to get your hands on a box of rounds. Because of that, we will strictly focus on energy that is accompanied with the bullet and will be transferred to the target and the amount of penetration you will get on the target.

There are people out there we might trust, but the best way to test which round is the most accurate with your rifle is to shoot it yourself. Reproduction in whole or in part without permission is prohibited. While the 7mm-08 had several rounds that could break the 1,200-yard mark, the .270 Win had many more options and even a few that remained supersonic out to 1,300 yards. With the long-range trajectories of these cartridges, both can be used for long-range shooting. There is less than two inches of difference between the averages for these two cartridge types with the .270 Win having a slight advantage. Higher velocities increase penetration as does highly bonded bullets that will not fragment on impact. Girlfriends come and girlfriends go.....the rifle stays. 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. 39.50 € Ajouter au panier. Of course, that is just averages, and you’re not going to be shooting averages in the field. The .270 is just in higher demand currently than the 7mm-08, and that means more companies are making more of that ammo. In this article, we are not setting out to pick one of the two as the best cartridge. On impact, this kinetic energy is transferred to the target where it causes damage to surrounding tissue and organs. Joined Oct 17, 2009 Messages 176. The vast majority of centerfire cartridges are going be at supersonic speeds when leaving the muzzle and maintain that speed for at least several hundred yards. We are not stating here that penetration depends solely on the sectional density of the bullet. I was most always hunting Deer when the Elk showed up. In our opinion, both sides of the 7mm Rem Mag vs. 300 Win Mag fence offers comfortable, efficient ‘seating’! Go. As you can see, the trend is very similar to what we saw above. From the larger data set, we see there is still not much difference between these two cartridges and their associated bullet momentum. The sectional density alone does not indicate penetration. Play around with the BC and you will find that you can shave off a couple inches. Many products featured on this site were editorially chosen. So, how we are going to look at accuracy is to reexamine several of the ballistic and performance characteristics that we have already taken a look at. The BC of this round might not be as high as long-range shooters would like to see, but the flat trajectory might compensate for this with a bullet drop of only 33 inches at 500 yards. Just like the smaller sample set in the bar graph, these two cartridges have very similar averages for the ballistic coefficient. Je chasse en général en battue le chevreuil dans l’indre, mais aussi en creuse le sanglier(on ne tire pas le chevreuil et il n’y a pas de cerf), et pour finir, je suis assez fréquemment invité au cerf, chevreuil et sanglier avec mon association de jeunes chasseurs ou par des proches. The gap only widens slightly as the rounds move out to the 300-yard mark with the .270 Win rounds showing an average bullet drop of 11.16 inches and the 7mm-08 Rem rounds showing 13.3 inches of bullet drop. This does not mean we think it the absolute best round, it’s just one that sticks out to us. Both of these cartridges can be fitted with similar weight bullets, and both have slender profiles and similar velocities. It is also rated to handle 5,000 more psi of pressure than the 7mm-08 cartridge. Depending on your hunting or shooting situation, there are going to be rounds available for both cartridges that will give you the wind resistance that you need. We have included the average tables below for reference. The second metric that we will look at to gain some insight into the potential penetration of these two cartridges is by looking at the bullet momentum. With the power to throw a powerful punch, the Hornady round could easily catch an average whitetail by the use of a relative case. Although the wildly popular 6.5mm Creedmoor is a better long-range target cartridge, Boddington believes both the 7mm-08 and .270 are better hunting cartridges. So with recoil in mind, let’s take a look at several ballistic characteristics of the 7mm-08 vs .270. Thus, hunters and gun writers argue about which is the better choice between 6.5 Creedmoor and 7mm-08 Remington. And if you were to look at the individual rounds, you would see that both cartridges have rounds that occupy the same range at each yard marker. The .280 has spent most of its life pinched between the popular .270 and the 7mm Remington Magnum, and it competes against several other commercial 7mms as well: the blazing fast 7mm STW and 7mm Remington Ultra Mag and the low-recoiling 7mm-08 chief among them. That’s about as similar as you can get. For more experienced shooters, the difference in recoil might not be as large a concern unless it is a dramatic difference. Sectional density plays a role in momentum as more momentum is conserved when the projectile, a bullet in our case, is striking a smaller area. We are limited in space, and ten rounds seemed like a nice round number. Cons: Lengthy action and heavier gun. The velocity of the bullet plays a critical role in just about every ballistic and other performance categories we will look at. In the following graph (Graph 4) we are only going to look at two rounds, one from each cartridge type. Joined Jan 31, 2016 Messages 3. Was wondering does anyone have much experience with the newer 7mm WSM (short mag) and how you think it compares to my Win mod 70 .270… A.435 B.C. The bullet of the .270 also does not sit down in the casing enough to reduce the cartridge space so with a case length of half an inch longer, and the same difference in overall cartridge length, it can hold more propellant. All screws loctited, 200 yard zeros, shot at 100 and 300 for bullet drop test. All of the selected rounds are factory loads that are readily available to us consumers. A bit more than the 7mm Rem. I am 17, and I hunt mule deer in southern Oregon where it is pretty open and flat. The difference is not too severe and like the earlier graph, there are 7mm-08 Rem rounds that have sectional densities around or better than the .270 Win average. MeatEater’s 7mm-08 Big Game Bullet Choice: Federal Premium 140 grain Trophy Bonded Tip.270 Winchester If there’s a big game cartridge that perfectly bridges the gap between the mild .243 Winchester on the low end and the powerful .300 Winchester Magnum on the top end, it’s the time-tested .270 Winchester. Go. I know many local stores ( Walmart, Meijers, Dick's, etc. ) In fact, those two cartridges are likely among the Top 10 best selling rifle cartridges in the United States each year. There are several rounds of both cartridges that have BC’s above the .45 mark and also rounds for each cartridge at above the .48 mark. We have selected five individual rounds for each cartridge type. The 270 Winchester remains one of his favorites, but it's sharing field time with several 6.5 Creedmoors and other 6.5mms. You will often find a lot of people fixated on the velocity of the bullet, and while velocity is important, they often lose sight of why it is. In the next year or 2 I will be heading to Idaho for elk and mule deer (have a friend who lives there). We will also examine the sectional densities for each round we have selected to represent both cartridges to determine the amount of potential penetration. Next Last. Le seul bémol, c’est que j’hésite encore sur le calibre: 270 win ou 7mm RM. The best performing rounds were all .270 Win, but there were a couple 7mm-08 rounds that competed. The top two flattest shooting rounds were from the .270 Win cartridge. Naturally, the longer the shots, the more wind and other environmental factors will have an impact on the flight of the bullet which is why more weight is given to the BC. At 200 yards, all of the rounds are still clustering pretty tightly, but we do see the rounds from both cartridge types begin to cluster with each other with the .270 Win rounds having a slightly less pronounced bullet drop. Whether it is while trying to line up the crosshairs on a trophy buck when the adrenaline is pumping, or it can increase fatigue from a day on the range and make those last few shots seem to miss by a few centimeters. Too much velocity with an incorrect twist rate or a certain bullet design and you can get an unstable flight which leads to inaccuracy. The same can be said for the individual rounds of each cartridge as well. Of the top two performing rounds of these cartridges includes a .270 and 7mm-08 round. 1; 2; Next. Jack Naylor. Jan 31, 2016 #1 H. Hotrod New member. Mag., substantially more than the old 270 Win. This kinetic energy is a product of the mass of the bullet and its velocity. ; All measurements are in mm (in), and all charts are sortable by clicking on the icon beside the title of the column you wish to sort. We have calculated the sectional density for each of the ten rounds used in this comparison and graphed them here (Graph 8). So, these numbers might change a bit given the length of your rifle’s barrel, but that change should be similar to any round you put through the weapon of that same cartridge and caliber. Again. I am a big fan of the 30 calibers but I also found that one can do more with less when using the 7mm. There is still some overlap between the individual rounds and you will find several 7mm-08 rounds that have KE numbers in the higher tiers with the .270 Win rounds, but you do see the .270 Win rounds have a lot more options when it comes to rounds with 2,800+ kinetic energy numbers from the muzzle. This is especially true for cartridges popular among long-range marksmen and hunters. If we do look at these two cartridges, the 7mm-08 rounds all fall below the 20ft.lb mark but the .270 rounds are not too far off. Of course, bullet design (including sectional density) and expansion also influence a rounds ability to penetrate. The .270 can be thought of as a necked down version of the .30-06. The 7mm Remington mag is well established but not so versatile as the .30-06. He was originally going down to 6.5mm but changed his mind and went up to 7mm. then we come to the 175 gn 7mm bullet in 7mm. If you hand load then the story changes as 7mm has a greater bullet selection from 100-180gr bullets vs the 270's 120-150gr. Next Last. Tags: None. I think it’s true for most of us that if a round has proven itself to us, we won’t mind shelling out a few more dollars. While the .270 Win rounds might have the slightest advantage in sectional density over the 7mm-08 rounds when looking at their averages, we don’t think it means you should conclude that the .270 is going to be a better cartridge for killing game.
