I used T/C 320gr Maxi-Balls to take 10 elk and one deer in NW Colorado with my 50cal Hawken. All excepting one accidental spine hit ran about 30' and fell stone dead with complete pass throughs. I shot the bullets with 90grs FFG Goex in a 1 in 48" twist barrel with about 1-2" three shot accuracy at 75 yards.
I have no idea, and make no claims that they're the best choice. I bought them and gave them a try mostly on impulse. PBRs shoot more accurately in my rifle using less powder, but I didn't feel confident with them. I was hunting alone with limited time for carcass retrieval, and desired some mass for such big animals.
