Other than 30-06 and 8mm Mauser, what were the best rifle cartridges of WW2?

7.7 Jap
Just because it was basically the original .303 British rimless design that was going to be adopted before that one officer autist fucked it all up

Didn't meant to respond, oops.

Story time?
I only say 6.5 swed because my AG-42 rips right through steel (something about cross sectional density being higher) and has pretty good accuracy. That being said my K98K is Russian capture and therefore not the best quality and I haven’t compared it to my m8’s Enfield yet. I won’t even bother with my Mosin, and I have no access to a Arisaka and I’ve only seen two Carcanos at gunshows. So I suppose I shouldn’t have even voiced my opinion.
