WHAT DO YOU LOAD YOUR 375 H&H WITH? IM THINKING ABOUT USEING A 300 GR BULLET, DONT WANT A DOWN LOADED LOAD I WANT ALL I CAN GET OUT OF IT, ALSO NEED SOME CASES? CSA
I don't shoot mine as much as I did 25 years ago, but those are the two powders I've used most in the past. I always liked the 235gr bullet (because it is only 235 grains), as well as the 300 Sierra Boat Tail because of its excellent ballistic properties. I also shot a lot of the Hornady 270gr flat base, because they were cheap(er). If I were going to be buying components today, I would probably buy Nosler Partitions.
IMR 4064 is more accurate in my experience, IMR 4350 gives you a bit more velocity. Some links:
I think the best powder for the 375 H&H Magnum is probably RL-15.
At 100 yards off the bench shooting 3 shot groups, I get about 1.5 inch groups with Hornady 300 gr. BTSP bullets and less than 1 inch groups with Hornady 300 gr. FMJ round nose bullets.
Another thing about the 375 H&H Magnum; the cases tend to stretch a lot and early. Be sure to check the case length and trim as needed. Also, run a paper clip with the tip bent down the inside of the case to detect the groove that starts before head separation.
Well, you specified full-tilt-and-boogie, and 300gr bullets. Sooooo...
My biggest grin-getter was a 72gr of H4895 behind a Speer 235. Probably ~ 2600, not too unpleasant. Never shot it at game, but it would really shoot tight groups ~ 3/4" at 100. I bet it would mow down any deer and most elk.
