With powerbelts, you have to be carefull and stay within the powder limits of the bullet. I think they recommend no more than 90 grains powder for the 295 lead hollow point. For deer, that should work just fine. For elk, I want something bigger, and not such a big hollow point on it.
I have taken two elk, one with a 370 grain T/C and the other with a 385 Hornady. Can't remember what I shot my one deer with?
