Size of game with supersonic 125 gr TNT?

Thanks 320pf

I've searched and read threads for "TNT" and "Speer" but I didn't find anything specific about the how the TNT bullet reacts at these velocities. I have a hunch that it might be a bit more explosive than the Sierra 125 and Nosler 125 info that I did find here.

Your are right. There are no direct comments on the TNT performance on game. But they should work like a charm on deer at 300-221 velocities. I would not hesitate using them. I shoot them in 3-gun matches and they are very accurate. I can consistently get 0.6 to 0.7 inch 5 shot groups at 100 yards.

What is the desired twist for stabilizing the 125's for 2000-2500 fps range ?

is 8 cool or 10 better ?

I've had good luck with the 125 TNT's at 2500 fps out of a 1:11 twist
