I'd be interested in finding out what those Cor-bons actually do. Please let us know when you try some.
I have pushed .357 125gr JHP at 2200fps in a Marlin carbine. That is just something you cannot do in an M1 carbine.
Unfortunately, the regular 125gr .357 JHP is not well suited to this high speed. Expansion is ...energetic, and penetration is correspondingly reduced.
The 158gr JSP is a better choice, and handles the carbine velocity much better. And no .30cal carbine load can quite match the 158gr .357 performance on game.
Bullet weight, speed, and size, the .357 out performs the .30 carbine in every useful way I can see.
All else being equal (and it almost never is) bigger bullets tend to work better.
