[KrautKiller16]

Well, it makes sense:

Mauser Gewehr 98K: 7.92x57mm (gigantic death bullet!)
M1 "Garand": 7.62x63mm A.K.A. .30-06. (also a gigantic death round, but a bit smaller to be handled in semi-automatic fire.)

You can't really say they have varying levels of "punch"--the Mauser's bullet wasn't that much bigger, and both bullets can easily kill with one round virtually anywhere on the torso.

Now, MP40 vs. Thompson: This is different. Here, we have one of the all-time battles:
9mm VS. .45!!!!
Both of these submachine guns have almost equal recoil. The MP40, because it's so light, and the Thompson because, even though it's heavy, it fires dang 230-grain .45 ACP rounds and kicks like a mule, as all .45s do.

And I prefer the Springfield to the Mauser sniper.
