Anybody got a good load on this. Doesn't have to be to the gills. I've used the 270 Xbullet with 74 grains of RE15 at about 2700, I have some H380, Re15, H414, and IMR 4350 (not my first choice). Also have some BLC-2 and Vit 150 (might be a bit fast). Out of a M70 Classic.

I like RL-15 in the 375 H&H Magnum. Was there some reason you didn't like that powder?

I have used the 270 X bullet in a Weatherby .375 H&H and at 71.0 grains of RL-15 I get 2600 fps. I have used the 300 gr TSX with 68.0 gr of RL-15 I get 2604 fps in an M70 SS Classic.

My .375 H&Hs like RL-15.

Grum: RE 15 shoots good in my 375. Will do 1 moa with 270 Hornadys and xbullets. Just fooling around with different powders. I am trying some 380 just for kicks. The Xbullets really fouled my barrel bad. I got good accuracy with IMR4320 also, but understand it is temperature sensitive, though I never noticed. A friend in Ak got some hangfires and high pressures at cold temps with 4320. I think he is sticking with Re15. Another guy likes 4350, but I think it is a bit slow. I am also going to try and work up a Vit150 load. I got some on sale. I also will try BLC2 with the Sierra 250. Want to use the TSX's on elk though!

Paul, It may or may not help you with 270gr TSX's but I've gotten great accuracy with H-4895 and 300 gr X bullets in two different 375 H&H's. H-4895 is usually a little quicker than RL-15 so I'm thinkin it would be the first powder I'd try with the 270 TSX's since it worked so well with the 300 X's. The fact that H-4895 is temperature insensitive doesn't hurt anything either.........................DJ

You might try Varget. One thing about it is it has better lot to lot consisency than RL15.

I've found that if you find a good lot of RL15 buy as much as you can safely store and forget about anything else in the 35 H&H.

Thanks guys. Looks like I have to buy another powder cannister. I do have more use for them, though. Will let you know what happens with the H380 vs 4895 and Varget.
