Hi there, I'm John McAdams, founder of the Big Game Hunting blog, and in this video I'm
0:05
going to do a detailed comparison of the .270 Winchester and .30-06 Springfield
0:09
cartridges. Now most hunters and shooters probably agree that the .270 and the .30-06
0:15
are both very versatile and effective big game hunting cartridges. After all
0:19
there is a reason why they are consistently among the two most popular centerfire rifle cartridges used by hunters in the United States. Now while
0:28
there is an overlap in their capabilities, the two cartridges are best suited to different tasks and represent two different ways of thinking
0:36
This is part of the reason why each cartridge has such a dedicated and loyal
0:40
following and why the .270 vs. .30-06 debate continues to rage on after so
0:46
many years. So in this video I'm going to discuss the merits of the .270 vs. the
0:51
.30-06 and I'll provide some insight into which cartridge you should be using
0:56
in various situations. The US Army designed the .30-06 Springfield for use
1:01
in the bolt-action 1903 Springfield rifle in 1906 as an improvement on the
1:06
.30-03 Springfield cartridge. The Army was just coming off the heels of a
1:10
sobering lesson regarding the effectiveness of the new 7mm Mauser cartridge in the hands of Spanish troops in Cuba in 1898 and wanted a
1:18
cartridge and rifle that could compete with the revolutionary new Mauser. Using
1:22
smokeless powder and a new 150 grain pointed bullet fired at a muzzle
1:26
velocity of 2,700 feet per second, the .30-06 Springfield was a significant
1:31
improvement over previous cartridges the military used during that era like the
1:35
.30-40 Krag and the .45-70 Government. It didn't take long for the .30-06
1:40
Springfield cartridge to catch on with the hunting and shooting communities and it was soon an extremely popular cartridge in the United States and in
1:47
North America as a whole. As good as the .30-06 Springfield was, not everyone was
1:51
completely satisfied with it and Wildcatters quickly started modifying the cartridge for more specialized tasks. Around the same time gun designers were
1:59
necking the .30-06 up to develop the .35 Whelen cartridge, engineers at
2:03
Winchester decided to go the opposite route and neck down the .30-06, well
2:08
specifically the old .30-03 case, which the .30-06 is descended from, to use
2:13
.277 caliber instead of .308 caliber bullets. The resulting .270 Winchester cartridge was formally released in 1925 for the Winchester
2:24
Model 54 rifle. The original .270 load shot a 130 grain bullet at a blazing
2:30
fast velocity, for 1925 anyway, of 3,140 feet per second. Though the .270
2:36
Winchester was not an immediate success, American hunters appreciated the flat-shooting characteristics of the round and the fact that it was so
2:42
effective on thin-skinned game. The cartridge gradually became more and more popular, which was helped by Jack O'Connor and his famous affinity for the
2:50
cartridge that he expressed in countless outdoor life articles over the years. Now
2:54
that's not to say the cartridge only became incredibly popular because of O'Connor. Now while he did indeed love the .270 and used it extensively on hunts
3:02
all over the world, it was far from the only cartridge he used. The .270 was also
3:06
a good enough cartridge and filled a big enough niche that it probably would have
3:10
been successful even without any help from Jack O'Connor. Now the .270
3:14
Winchester is something of an oddity when it comes to bullet diameter though. Unlike all the other popular 7mm cartridges like the 7mm
3:21
Mauser, the 7mm 08, the 7mm Remington Magnum, and the .280 Remington that use .284 caliber bullets, the .270 uses .277 caliber
3:31
bullets. It's unclear exactly why Winchester decided to go with .277 instead of .284 caliber bullets with the .270. One theory is that they chose that
3:41
particular bullet size based on an obscure 6.8x57mm Chinese Mauser cartridge. It's also possible they wanted to create a distinctly American
3:49
bullet size and avoid the 6.5 and 7mm bullets popular in Europe
3:54
by using a brand new bullet diameter 10% smaller than the one used in the .30-06
3:59
So .9 multiplied by .308 is .277. Regardless of their reasons, the design
4:05
team at Winchester went with the .277 caliber bullet diameter and the rest is
4:09
history. Interestingly enough, while the .270 turned out to be a smashing
4:13
commercial success for the company, .277 caliber bullets really never caught on
4:18
elsewhere. The .270 Winchester Short Magnum and the .270 Weatherby Magnum are
4:23
the only two mass-produced cartridges that use bullets of that size. Not
4:27
surprisingly, the .270 and the .30-06 cartridges look very similar to each
4:31
other. The .270 does have a slightly longer case length, but the two
4:35
cartridges are identical up to the shoulder and have the same maximum
4:39
overall length of 3.34 inches. For this reason, both cartridges are used in
4:44
long-action rifles. Now, since the .270 uses a neck-down .30-03 Springfield case, which the .30-06 is also descended from, both cartridges also have the
4:55
exact same case diameter and virtually the same case capacity. In short, aside
5:00
from the fact that the .270 shoots .277 caliber instead of .308
5:05
caliber bullets and the fact that the .270 has a tiny bit longer case length
5:09
the two cartridges are virtually identical. However, those small changes make a big difference when it comes to ballistic performance. The .30-06 is
5:18
certainly no slouch in terms of velocity or trajectory, but the .270 has a clear
5:24
advantage in both of those areas. By necking down the .30-06 case to shoot
5:28
smaller diameter bullets, the designers of the .270 were successful in building a
5:33
cartridge with a higher velocity, flatter trajectory, and less recoil than the .30-06. This is because when compared to the .30-06, the smaller diameter
5:42
.270 Winchester shoots lighter weight bullets. For instance, the vast majority of .270 Winchester factory loads shoot bullets in the 120 to 150 grain range. Of
5:52
these, 130 grain and 150 grain bullets are by far the most common. On the other
5:58
hand, though it is possible to find .30-06 ammo using bullets weighing as
6:02
little as 110 grains, most .30-06 Springfield factory loads use heavier weight bullets in the 150 to 180 grain range. There is a significant difference
6:14
in the bullet trajectories between the two cartridges. When comparing typical factory hunting loads, the .30-06 bullets usually have as much or slightly more
6:22
energy remaining at 500 yards, but the .270 bullets will still hit around 4 to 8
6:28
inches higher at that same range. Not only does the .270 have a noticeably
6:32
flatter trajectory, but most factory .270 loads will have about 20 to 30 percent
6:37
less free recoil energy than typical .30-06 loads. It's tough to pick a
6:42
winner when it comes to accuracy of the .270 versus the .30-06, because it's
6:46
something of an apples-to-oranges comparison. Most people agree that both cartridges are capable of excellent accuracy, but the .270 Winchester is used
6:54
almost exclusively as a hunting cartridge, while match shooters, military police snipers, and hunters have all used the .30-06 extensively over the years
7:02
For those reasons, the big ammo companies have invested a tremendous amount of
7:06
time and resources in developing a really big selection of high BC, match
7:10
grade .308 caliber hunting bullets that are available for use in the .30-06
7:14
On the other hand, since the .270 has almost exclusively been used as a
7:19
hunting cartridge, the major bullet manufacturers have not invested nearly as much time developing heavy-for-caliber, high BC .277 caliber bullets. Now that's
7:28
not to say the .270 Winchester isn't an accurate cartridge. It most certainly is
7:32
but it just doesn't have the same pedigree as the .30-06 in that regard, and
7:36
for that reason, there are very few choices available for .270 match ammo. Now
7:42
all that being said, both cartridges have the potential for excellent accuracy in
7:46
the right hands, and will absolutely do the job at reasonable hunting ranges. Now
7:51
let's talk about ammo and rifle selection. The .270 and the .30-06 are two of the
7:56
most popular cartridges for hunters in the United States. For that reason
8:00
virtually every ammunition manufacturer of note, like Barnes, Browning, Federal, Hornady, Nosler, Remington, Swift, Weatherby, and Winchester, just to name a
8:09
few, produce a wide variety of good quality ammo and various bullet weights
8:13
for both cartridges. So regardless of whether you want lighter or heavier
8:17
bullets for either cartridge, you should be able to find what you're looking for. Just about every major style of bullet is available in those cartridges as well
8:24
like the Barnes TTS-X, the Hornady GMX, Interbond, and SST, the Nosler Acubond and
8:30
Partition, the Remington Korlacht, the Swift Sirocco and A-Frame, and the Winchester Powerpoint. Prices and availability vary from region to region
8:39
but ammunition for both cartridges is widely available. In fact, if a sporting
8:43
goods store only carried ammo for two different centerfire rifle cartridges, I'd bet money they'd have .270 and .30-06 ammo. Prices for both cartridges are about
8:53
the same as well. If you're into hand loading, then you're also in luck because reloading components for both cartridges are widely available. There are lots of
9:00
good quality .277 and .308 caliber bullets to choose from, so you shouldn't
9:05
have much trouble working up a custom load that shoots very accurately in your
9:08
rifle. Now since they're both such popular cartridges, there are also lots of
9:12
rifles to choose from, and virtually every firearms manufacturer produces rifles chambered in both .270 and .30-06. Additionally, because the cartridges are
9:21
the same length and have the same rim diameter, rifles of the same model
9:25
chambered in each cartridge are virtually identical to each other. Among others, the Browning X-Bolt, the CZ 550, Mossberg Patriot, Remington Model 700
9:34
Ruger American and M77 Hawkeye, the Savage 111, the Thompson Center Compass
9:40
the Tikka T3X, the Weatherby Mark V and Vanguard, and of course, the
9:45
Winchester Model 70 are all available in .270 and .30-06. As anyone who has read a
9:50
few of his articles in Outdoor Life would know, Jack O'Connor's favorite rifle was a Winchester Model 70 chambered in .270 Winchester. Even though
9:58
the Model 70s have been chambered in many other cartridges, including .30-06
10:02
and even though many other rifles are available in .270 Winchester, the Model
10:06
70 and the .270 Winchester remain forever linked in the minds of many hunters due
10:11
to O'Connor's work. By the way, if you want to see it for yourself, O'Connor's Model 70 is currently on display at the Jack O'Connor Museum in
10:18
Lewiston, Idaho. He first purchased that particular rifle in 1959 and used it on
10:23
hunts all over the world for a wide variety of game. He took his last stone
10:26
sheep with that rifle in 1973. So, which one is right for you? When using the
10:31
right bullets and with good shot placement, both cartridges are excellent for hunting medium to large size game. Indeed, both the .270 Winchester and the
10:39
.30-06 Springfield are great choices if you're looking for a really versatile cartridge. They're both extremely effective and popular deer
10:46
hunting cartridges. Indeed, whitetail deer probably make up well over half the game harvested by those two cartridges each year. The .270 and the .30-06 also
10:54
work very well for feral hogs and black bear hunting. The same goes for exotic
10:58
game like Sika, Axis, and fallow deer. However, this is where the strengths and
11:02
weaknesses of each cartridge start to diverge. The flat trajectory of the .270
11:07
makes it great for animals that are more likely to require longer shots like mule
11:11
deer or pronghorn. By the same token, the fact that the .270 also has a relatively
11:15
mild recoil also makes it a great cartridge for mountain hunts where a
11:19
lightweight rifle is really desirable. After all, there's a reason why Jack
11:23
O'Connor liked his .270 so much for hunting sheep and why it's still such an effective cartridge for mountain goat and bighorn sheep hunting. On the other
11:30
hand, since it shoots a heavier and larger diameter bullet, the .30-06
11:34
Springfield has a clear advantage when hunting larger species like caribou, elk
11:38
and moose. When using a 180 grain bullet, the .30-06 also has a big advantage when
11:42
hunting most species of African plains game. Now that doesn't mean you can't
11:46
hunt elk, moose, or plains game with a .270. After all, many hunters have killed
11:51
untold numbers of those animals with the .270 over the years. If anything, the .270
11:55
is even more effective on really large game, elk hunting in particular, now than
12:00
it was even 20 years ago because hunters now have access to much better quality
12:04
bullets. For example, a friend of mine has used his .270 with great success on
12:08
caribou, moose, and kudu. Heck, he even cleanly took a blue wildebeest, which is
12:14
a notoriously tough animal, with that same .270. Now, bullet selection is very
12:19
important though, and he used 150 grain nozzle partitions on the kudu and the
12:23
blue wildebeest. Additionally, there is a little bit less room for error with shot
12:28
placement when the .270 on really big game, but it can still be an extremely
12:32
effective cartridge if the hunter is up to the task. There's also nothing saying
12:36
that .30-06 isn't suitable for long-range shots, or that it can't also be a
12:40
great rifle for a mountain hunt. Like I said earlier, they're both quite versatile
12:44
but it's just that each cartridge is just a better choice for certain applications. So, do you primarily hunt deer, hogs, or bear in an area where long
12:53
distance shots past 200 yards are uncommon, and bullet drop isn't really a
12:57
concern for you? Both cartridges will work just fine under these circumstances
13:02
and there isn't much difference between them inside 300 yards. Now, are you
13:06
sensitive to recoil, or maybe you do a lot of mountain or backcountry hunts
13:10
where it's really nice to have a lightweight rifle? Consider going with
13:14
the .270, which is a lighter recoil that's more manageable in a small
13:17
lightweight rifle. With good shot placement and quality ammo, the .270 is a
13:22
wonderful choice for mountain goat, sheep, or tar hunting. Do you want to hunt
13:27
larger game like elk, moose, red stag, and elan? Both cartridges will work, but the
13:32
.30-06 offers a clear advantage since it can use heavier 180 grain
13:36
bullets that are much better suited for extremely large and or tough animals
13:41
I personally would lean towards the .30-06 in this case, but that's just me, and
13:45
there's not a darn thing wrong with using the .270 either, as long as you're
13:49
aware of its limitations. As I've stated before, the .270 and the .30-06 are both
13:54
great rifle cartridges. While each one may be better suited to specific
13:58
situations than the other, they're both very solid performers overall. The difference between them is not as great as some people think, and the animal will
14:06
never know the difference if your shot is placed in the right spot. Now if you
