Also considered rebarreling one of my 270's to a 270x300 Win Mag. I like the .270 for its flat shooting and hard hittting abilties over long range. 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. 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. My solution to this dilemma was to have one of each, (I actually have 2 .308s) in addition to the .30-06. Thoughts? In fact, a 150gr .270 has better sectional density than 180gr .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. This can cause excess barrel wear and damage. All cartridges/rifles are a balancing act between Many western hunters annually take elk with 6mms and .25s. Two of the most highly debated between are the .308 Winchester round and the .270 Winchester. The .270 was also commercially produced by Winchester, hence these two rounds being fairly similar but with some good differences as well. The .308 commonly has a 150 to 180 grain range. Let’s break down the differences in speed of travel and force of impact with the .270 vs .308. For target shooting, knock yourself out and take both to the range and have a ball. I’m more than happy to shoot inexpensive bullets like Speer Grand Slam (180 gr and 175 grain, respectively) out of a 308 or 280 Rem. The end of this Season 270 vs 308. It’s unclear exactly why Winchester opted for .277″ instead of the much more popular .284″ bullets. Regardless of their reasons though, the design team at Winchester went with that bullet diameter and the rest is history. Case capacities for the .270 Win and .308 Win were obtained from Nosler. Those same characteristics also make it a very good choice for mountain goat in Canada or Himalayan Tahr and chamois while hunting in New Zealand. 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. 223/5.56 vs 7.62×39: Everything You Need To Know. Dec 11, 2017 #7 H. HARPERC Well-Known Member. Buy an excellent .308 Winchester hunting rifle here. I have done BC calculations on Hornady website and a .308 shoots just as flat and with more energy than a .270 when you get up to 150 and 160 gr bullets for the .270. The .270 Winchester might be the better choice for you. The .270 Winchester vs. the 7mm Remington Magnum. The .30-06 isn’t fancy or flashy, but with a 180-grain bullet it’s a real thumper. Just a few years after the introduction of the .308, the wildcatters mated the case with 7mm bullets. I think your bigger decision is the bullet you use, use a good quality bullet. Some recommended products may use affiliate links. Bullet selection becomes really important with a 150 grain pill fired out of a .308 intended for elk. However, since most modern .30-06 factory loads have a small edge in velocity (usually around 100-200fps) over .308 factory loads shooting the same weight bullet, the advantage in velocity of the .270 Winchester is even more pronounced when compared to the .308. As we have discussed throughout this article, the choice really comes down to you and your purpose that you have in mind as you choose between these two different rounds. 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. But, even then I think the hunter is on a very thin edge of killing efficacy. While each cartridge offers certain benefits to hunters, there is also a pretty big overlap in their capabilities. The .308 is absolutely enough gun for elk hunting. 150 grain, 165 grain, 168 grain, and 180 grain bullets are most popular for that cartridge. 165 Hdy SPBT's also shoot great in my rifle and would be happy with them.

The best success you have with either, will depend on your bullet. Not surprisingly, the .30-06 Springfield was an almost instant success in the civilian market. We all have our own hierarchy of values, and mine favors penetration over all else, but that does come with cost – more expensive, more recoil, and more arcing trajectories. 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. I think this is where we begin to make our biggest distinctions between the rounds. 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. Specifically, the military wanted a new rifle chambered in an intermediate cartridge, capable of automatic fire, and equipped with a detachable magazine. Heavier, more stoutly-constructed bullets are almost universally better at penetration, given their lower velocities. However, the flat trajectory and resistance to wind drift of the .270 Winchester makes it a really good choice for game that might require a longer shot such as pronghorn or mule deer. 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. 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.

However, the .308 performs better with heavier bullets than the .270 and is available in a wider range of bullet weights and models. But if I were to go out west and shoot long range it would be a toss up between the 308 and the 300 win mag. 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 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. Two rifles that are known to compete against each other. I shoot a 338 at elk nowadays but I used a 270 for years with tons of success.

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. Left to right: Winchester’s .270 is gentle in recoil but lethal. The fact that the .270 and .308 each have very devoted fan clubs can also make it difficult to navigate the debate. Due to the cartridge angle and the diameter of the headspace it barely contains enough powder to send a 165gr round to punch a hole in an antelope with premium bullets. I used the Federal Ballistic calculator and ShootersCalculator.com to compare wind drift, the range each bullet goes subsonic, and recoil for the cartridges. While recoil is more or less comparable between the two cartridges, typical .308 Winchester loads do not have as flat of a trajectory as typical .270 loads.

The .308 Winchester and .270 Winchester are two of the most popular centerfire rifle cartridges in North America. On the other hand, even though the .270 Winchester does shoot flatter in many cases, military and police snipers, hunters, and practical and/or long distance shooting competitors have all used the .308 Winchester extensively over the years.

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). 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.
