70 grains RL-15, my 375 is shooting well with 300 grains,AF and Barnes TSX. Federal 215M primers.

I know a guy who hunted deer once in a while with his 458WM, just to be able to shoot it on live game here. However, for the deer he used 5744 to develop what he called a “bowling ball” load. LOL!

Hahaha, that would be fun. I have 3 or 4 casting molds for 375 caliber for my 38-55 lever action. I could down load and shoot the cast bullets in my H&H

I wish I had more R-15. My rifle shot 68.0gr and the 300gr AF very well

Not sure of 15 but 15.5 is avalable Link. I have heard lot of good things and similarities about 15.5 and some reports indicate it to be more temperature stable.

23gr. Unique was the load with the RCBS 250gr. FN GC I used in my .375 M602 BRNO for 3 position shooting in 1973 until I built a .308 match rifle. The cast load (no filler nor wad) held 1 1/2" at 100 yds. with the pop-up peep sight. With a scope it would likely have been under an inch. I made sharpshooter with that rifle & load, one category up from marksman(the start). LOL
Recently(10yrs ago), I shot some 300gr. GC FN's from my .375/06IMP with 13gr.(I think) Trailboss. They chrono'd 1,380fps and would have made a good deer load, shooting 1 1/2" with scope set at 4X. Might have been 13 1/2gr.- but full case to the base of the neck, where the base of the bullet was. Full case with no compression. I suspect a .375 H&H would shoot similarly. A no-recoil go-pow load.
