Brad aka Pill Shooter375 H&H 300grn Load
I finally got around to cleaning up a Mod 70 375 H&H that came my way a few months ago. The last loading I did for the 375 was 76grns of IMR 4350 which worked well. I was wondering with all the new powder out does anyone have a great new load? Feel few to send me a PM if you don't want to post it in the open.
Thanks Brad

GerryBrad,
IME 75-76 grains of H-4350 witha 300 gr. Hornady RN has always deleivered outstanding accuracy for me, too. Not the speediest load but sure seems to deliver the goods upon arrival.
Cheers,

AMDPSU76gr H414 and a 300gr Fail Safe shoot groups as small as Jorge's in my Model 70.
H414 is an underappreciated powder in the H&H
I have been hoping to get equal accuracy with a new bullet now that the FS has been discontinued.
Hopefully Jorge has shown me the way.

DoglegJorge's load is within a grain of my own standard practice load. I use 77 grains of H414 or W760 with both 270 and 300 grain bullets. The only difference is that I use the standard primer instead of the magnum. For some reason there is a big difference in both of my .375's. My hunting load is the same, except the Hornadys stay home.

mstarlingMy load is 68.0 gr of RL-15 behind a 300 gr TSX on Remington cases with WLR primers. Yields 2604 fps average from a 24" bbl Win M70 SS Classic. Pressure was fine in Tanzania in August and early September.
All reloading data is rifle dependent ... so start lower and work up carefully!

Holly Crap that is the best group I have seen with Swifts. Is it consistant? I think I will try 414 in my 375.

Absolutely. It'll work with ANY 300gr bullet I tried it with. Two trips to Africa including a 350 yard shot at a kudu and a 25 yarder on a buffalo by a good friend of mine. I've tried in in temeperatures as low as freezing to over 95 deg (F). jorge

jetdrvrI get MOA from 76.5 IMR 4350 using A Frames and Hornadys. Shot over a thousand rounds and see no reason to change. I buy IMR 4350 8 lbs at a time.
Great group, jorge. Maybe next year when I run out of 4350 I'll try some 414.

TumbleweedFor the TSX fans;
I found that 300 gr. TSXs are very accurate with 67 gr. of IMR4064 / Rem brass / CCI 250 primers. I'm getting .7 MOA with a SAKO L61R, and MOA or a bit under with an old Browning Safari.
Has anyone here actually shot something with 300 TSXs?
How about the 450 gr. .458s?
I've seen poor terminal results (bullets not opening) with some of the smaller TSXs, but they admittedly have a much smaller aperture to begin with. I haven't tried the bigger ones yet in the field, but they sure are accurate.

AtkinsonAll these suggestions and posting of groups are fine, but a rifle is an individual and just because one gun shoots a certain load is no guarentee another gun will shoot the same load, even if all things are equal...
IMR-4350, IMR-4064 and H-414 are the usual best bets in a .375 H&H..Most of my .375s over the years have had a preference to the old and wonderful IMR-4064 but RL-15 is always right up there in the winners circle..

jwp475H-414 and Win 760 are to one another as H110 and W-296 are to one another... All are made by Winchester and H-414 and W-760 have nearly identical burn rates.

DWrightHave not been able to beat a full power load of IMR4350 for accuracy, but for a reduced power, fun to shoot a lot in a day type loads, I probabaly enjoyed 58 grain IMR3031 for a 2,300 fps more than anything else I can think of.
