You powder choice for the 375 H&H Mag?

[FOTIS]

Generally speaking for 250-170 gr bullets. Loads would be appreciated.

Fotis, I don't have a 375 H&H, but my friend does, and he does really well with RL-15 and the 270 Fail Safe.

My 375R really likes Big Game, and IMR 4895. I know its not a H&H, but they are not far apart.

 

[FOTIS]

That is the range I was looking at. H380 Win 760 H414 ......
A friend here in Cheyenne inherited a 375 and I am looking at powders to steer him (me actually) to buy the best one for loading it.

 

[jmad_81]

I tried H380, and H414 in my 375R, but it didn't like them.

I think most people are going to suggest RL-15.

 

[R Flowers]

My 375 H&H load is right out of the Barnes manual. A 270 grain TSX over a max load of H 4895.
Works for me.

 

[Oldtrader3]

IMR 4350 for 270 to 300 grain bullets.

 

[sask boy]

Fotis, I never shot anything but the 235gr speers so not sure if this would help but I only used IMR4895.

Blessings,
Dan

Like some of the others mine is a 375 Ruger, I would look at Big Game or one of the 4350's. I bet almost any medium burning powder should work well in it.

Funnily enough, Fotis, I've never loaded for the 375 H&H. I have, however, loaded on several occasions for the 375 Ruger. My "go to" powder in that cartridge is turning out to be IMR 4007 SSC. It gives good velocity with great accuracy.

 

[Guy Miner]

My most accurate load has been the 260 gr AccuBond, over 69 grains of RL-15 for 2620 fps. That's a minimum load according to Nosler, and it shoots real well. It's what I used on the black bear at 306 yards a couple of years ago. Got the load from John Barsness. More powder will of course make more velocity, it doesn't have to stay at that 2600 fps level. I just like it there.

For the 300's, I turn to 75 grains of H4350, again a load suggested by Barsness. It produces about 2550 fps with good accuracy.

Am using the Federal 215 magnum primers.

 

[Hamour]

IMR 4064 is my favorite powder for the .375 H&H Mag

 

[Guy Miner]

Hamour - I shot some 300 gr Sierras a buddy loaded over IMR 4064. Excellent accuracy and very low SD & ES figures. That was my "rockchuck load" last summer when I came across a varmint shooting opportunity and only had my .375 with me! :grin:

 

[FOTIS]

Thank you gentlemen....

 

[JD338]

Fotis,

Good luck with the load development.
Is Chris going to hunt with it this year?

The 375 H&H is not finicky with powders. I haven't loaded for mine in a few years but I used Win 760 the last I loaded for it.

 

[Laker_Taker]

300 accubonds and IMR4350 you cant go wrong. otherwise I still use it for the 270's as well.
