What is the difference between 7mm-08 and 7mm magnum (and ultra magnum)? Like the difference between .38 sp. and .357?
Welllllllll......not exactly.....with the .38 and .357 you can shoot the .
38 special round in a .357 Mag chamber.....you can't do that with the 7MMs you mentioned.....they only thing they have in common is a .284 diameter bullet.
Marty hit it pretty good on the power differences.....however all are more than adequate for any north american deer, pronghorn and even elk.
