Your favorite 375 H&H Recipe

[mrgoat]

Alliant R-15 is the powder I use in my 375 H&H. I don't have much left and it appears to be impossible to get it at this time from any source that I have contacted. In fact two reliable sources have stated Alliant may not ship any powders into Canada in 2014, I hope that is just nasty rumor.

Anyways what I do have on hand is IMR 4350, 4831, and 4064. All these will work. However my question is do any of you fellas have any pet loads with these powders which have worked well for you in the 375. The Nosler manual has many recipes but I am just trying to narrow things down a bit using the experience you folks.

For bullets I have 260 gr Noslers and 300 gr Hornadys. Thanks Guys.

My current standard load is RL15 and a 270 grain A-Frame. Prior to that I shot 78 grains of 760 or H414 and any bullet between 270 and 300 grains that i could get my hands on. (except the 300 grain Nosler Partition, I can't make make shoot in anything.) It didn't seem to make any difference which bullet or which rifle, everything shot and I never moved the powder measure. At the time thats how the data was listed on the website, which was more than likely a misprint. Shot out my first .375 barrel with that recipe.

80 gr. of IMR 4350 is a definite work up to it load as the Nosler reloading manual tops out at 75gr. and its full at 101%. Maybe a dump question to you fellas but I have no experience loading compressed loads. What's the trick to getting it all in and the bullet seated.

My current load is 69gr of RL-15 under a 260 gr partition. Accurate out of the M-70. I had it all the way up to 73 gr. but she was more accurate at 69. If insert the 300 gr. Hornady's it just slows things up and drops the point of impact a bit. Recoil is very tolerable, I equate it to shooting slugs from a 12 ga. But RL-15 is less common than hens teeth these days and may stay that way for a while. So I am trying to come up with plan "B" for a load using what's available and on hand. Thank you your reply's thus far.

Drop tube, and ignore the crunching noises as the ram handle bottoms out.

If a .375 doesn't shoot a 300 grain Hornady roundnose it probably wont shoot anything.
