View Full Version : M1A/M14 question.

Are ALL M1A/M14s .308? Or is there such a thing as one of these in 30-06?

They're all .308, or better yet 7.62 NATO. The action design will not handle the overall length of the 30-06. I should add that there have been some others chambered, like the .243 Winchester cartridge.

The M14 came after this country decided to go to the smaller caliber adopted by NATO. The rest of the NATO (along with most of the free world) adopted the FN FAL which was also 308.

I feel that I should add a little more, after I read my first reply. The action design is very capable of handling the 30-06 cartridge. The M1 Garand is the direct pedesessor to the M-14. The M-14 is nothing more than a redesigned M1 Garand, and the re-design included a receiver that was shortened, and modified to accept the detachable magazine. Other mod's and engineering will go without note. The bottom line is that the M-14 receiver is a shorter length, and will not accept the 59mm? length of the 30-06. It's just like comparing the Mini 14 to the M-14, there's no way to make the Mini 14 handle the .308 cartridge.

I'd love to find one of the .243 variations. I admit that I haven't been looking too hard for one, though.

One of the other calibers was 7mm-08, I believe that many guns ordered by most shops were .308 I haven't seen any of the 7mm-08's but I've heard of guys ordering the .243. There was some hope amongst guys who bear hunt and wanted to throw a bigger chunk of lead that Springfield or someone would make a .358 Winchester barrel for the M14/M1A series. But I guess the market wasn't big enough to overcome the technical hurdles.

.30/06 is 7.62x63mm, vs. the .308 which is 7.62x51mm.
There were some guys who would modify a Garand to take BAR magazines, but it's really a moot point.
Militarily, the 7.62x51mm does everything the .30/06 does, and it's lighter. There's still quality surplus available for the 7.62x51mm.

i always hear everyone say that, but nobody seems to be able to give me any real examples why a bullet traveling 200 FPS slower would accomplish that..help me out here..
i think they just changed because they wanted something a little cheaper

The military load for 150 gr. M2 .30/06 ball was about 2800 fps in WWII, the military load for 7.62 NATO is about the same with a 147 gr. bullet.
Now, commercially, yes, the .30/06 with modern powders does out perform the .308 with the same bullets.
