So I just came into a 375 H&H. I am going to reload for it. I have searched here and not found anything, unless I'm doing it wrong...

Any who I have been reading about the round and Ken Waters said that he found win 760 to be better for the heavier bullets and RL15 for the lighter. I am wondering what some of you are using for loads. I have lots of 760 to try things with but I will have to buy RL15.

I was thinking of using Barns bullets as as of late I have liked them alot. I was thinking somthing in the 250 range for everything on this side of the world and something in the 300 range for Africa.

Thanks.
 
GOOD PURCHASE

I went away from 760 (too temp fussy) and 4350 in my H+H and have had great results with RL 15 and 270 TSX my rifle really likes the 270 TSX and will consistently cut mickey mouses if I do my part. I found the 270 to be more than adequate for Africa up to and including two bean shot hippos. Shoots flat penetrates like crazy. I don't like different weights for 1 gun unless they completely shoot same impact at 100 and 200 yds, but thats just me. I highly recommend the 270 TSX IF your rifle likes them, not all do. My sons 375 Ruger loves 260 accubonds and he took 10 animals in SA last oct up to and including eland and he said performance was great and he made a couple 400 mtr shots with it to boot. Now he's using 760 and has good success.
I'm sorry, but I will not share my powder charges, too dangerous !! work up your loads from reputable loading manuals, period.

Ardent has several pet loads for the H+H that he's had great success with on a variety of game here and over there, if he doesn't tune in here you might want to PM him.

Congrats on the lovely new rifle and welcome to the "one gun fits all" club
 
Thanks. I will work something up and I do like to go hot. My 338 is about 6gr over max lol. I so far all my rifles like the barns bullets. I will have to take a run into Gp to find some 270tsx. I do have some 4350 in hodgon and imr. I will also have to get some RL15. The only thing I was thinking with the 760 was that it gave the highest Speed according to ken waters pet loads.

Thanks for the info.
 
I've used more W760 and the identical H414 in the .375 than anything else, with both 270 and 300 grain bullets.It's kind of handy when you are trying to get softs and solids shooting together and mixing in the magazine when you are useing the same powder in both. You may find that some of the velocities given for the .375 are hopelessly optimistist, but in any event RL15 gives me 150 fps more velocity with 270s in my current .375 and I'm switching over. I doubt that the 9 buffalo that old load killed noticed the missing speed, but ya never know.

I could never notice any difference between the 270 and 300 grain TSXs when it came to killing things, but the A-Frame seems to pull the H&H up a notch .:)

African hunting doesn't require the last bit of accuracy or velocity, all you need is a boreingly reliable gun and shooter and you will do fine.
 
H+h

Dogleg.....You notice extreme temp sensitivity with 760, like I have, in a number of cartridges?
I found the same as you with RL 15, added over 100 fps to the H+H with no increased pressure signs, not even in the 50+ heat in Zambia, I have read and believe the newer powders are a lot more stable and a lot less sensative to temp swings.

Bobjoe.....If you "like 'em hot" as do I, I can tell you my load chronographs through an Oehler 35P at 2925 at 25 deg C, 24" bbl and shoots like an '06 with 165 BT trajectory wise. Also I use the good old CCI 250 in this load, and the other thing I like is it is not a heavily compressed load as was 760 or 4350. I also trim and crimp all my loads for the H+H so the bullets don't creep under recoil (and they will) Last thing you need is a solidly jammed up magazine, that you can't get shells in or out, real pain in the a$$

I hate computers, Mr. Unhappy Face was supposed to be at the end not the beginning
 
I never had a problem with 760 in the .375, but I worked up and tested my loads in the summer here and shot them under very similar conditions in Africa. I'm more concerned about velocity and pressure swings on long range rifles and loads than general purpose hunting loads.

If a .375 is moveing its bullets under recoil there isn't enough neck tension. A crimp is a band-aid. TSXs are bad for this, but .003 neck constriction seems to take care of it.

The crimp does work though, haven't had any movement since I started crimping. I've noticed it more with the TSX, you're right. I might take the expander ball out and polish a couple thou off and see if that fixes it, so I don't have to trim every load, good to know.
My 450 Ackley was the worst for bullet creep, (something to do with the inertia of a 500 gn bullet and 93 ft lbs of free recoil, coupled with blown out 375 H+H brass and susequent thin necks) and that was before TSXs
