7mm-08 and .308

No, you cannot shoot a .308 in a 7mm-08 rifle.

7mm is .284 diameter. The .308 is --- .308 diameter. 7mm-08 is a .308 case necked DOWN to .284 diameter.

A .38 caliber bullet is actually .357 diameter - same as a .357 magnum. That's why you can shoot a .38 cartridge in a .357 magnum revolver. The difference between the .38 and the .357 is in case length and not bullet diameter. The .357 is longer than a .38 which is why you cannot shoot a .357 in a .38 revolver but can shoot the .38 in a .357 magnum.
 
I can see the confusion

Both are based off the same case and will look quite similar. You might be able to chamber a 7mm into a .308(with potentially disasterous results), but I don't think you could go the opposite.

Actually the case length on a 7mm-08 is .010 longer than a .308 (if i remember correctly). I tried chamber my handloaded -08 in my buddies .308 and when the cases are trimmed to proper length they wouldn't chamber easily. Im sure you could ram the bolt shut but who would do that. :rolleyes:
 
Case length have about .020" difference; the 28 caliber one being longer to prevent its use in the 30 caliber one.
