When I was loading jacketed bullets, I used the Barnes Original @ 0.377" diameter and 255 gr. I have gone away from the jacketed bullets now.
RL 7 and IMR 4198 gave good groups and I was looking for velocity around 1500 fps and there were no problems.
The remainder of those bullets are used in the 375 H&H.
IIRC, Barnes recommended an impact velocity of 1500 fps minimum for proper expansion in game.
I did not hunt with it back then, but I shoot a cast bullet for game now with a BHN 10 and gas checked.
