375 h&h + 250 ttsx

I just bought a Sako 375 H&H and am really wanting to use the 250 gr. Barnes TTSX in it. I will be using Nosler brass but am not sure which powder to go with yet. My manual suggests several IMR powders but I'd like something more temperature stable. Does anyone have any advice on powder or any load info to share?

Re: 375 h&h + 250 ttsx

Have been loading shooting the 375 H&H for years. Currently shooting the 270 Grn Barnes in one with IMR 4064 , 70.0 Grns. Powder seems very temp stable. My other "longer range load" used is H4831sc with the 260 Grn Nosler Accubond, Norma brass. I believe 78.2 grns (double check) out of 26 inch tube at 2744 fps no pressure. Groups in the .75 inch range considering the bullet diameter is .375 I'll take it! The Accubond has a pretty good BC and I have been shooting it to 800 yards very consistently. Overall I have had the best luck with 4064 and go back to that most of the time max loads are not compressed in the 70 grn range with 250 Grn Bullets and seems less pressure. Of course work your way up as I know I am close to max by most books.

Good to know, thanks for the info!

Do you remember where you started with H4831sc and the 260 AB?

on the 75 grn range. Again the 4064 provides better velocity.

Something like Varget or RL15 would be good choices with that bullet.

i was just wondering if you got around to shooting the 250 TTSX, and how it worked out for you?

Re: 375 h&h + 250 ttsx

I'd think of I 4320 for the 375 h@h. I'm using it with the 260 nosler ab and the 300 tsx and a cci mag primer in either rem or a-square brass. I'm getting 2550 fps and sub moa accuracy out of the rifle and it's a 8# er scoped.

Dang year old thread......
