Home Forums Hunting & Shooting Express Rifles and Big Bores Only Three Quarter Loads for a 375 H & H

Using jacketed bullets, does anybody have any recommended loads for the 375 H & H that are about 1/2 to 3/4 power. I plan on starting with these reduced loads and work up as I become accustomed to the recoil.

When I first started reloading for the 375H&H, i rolled up some "reduced loads" with Sierra 200 gr flat nose bullets and SR4759 powder.... Can not recall specifics, but, they actually shot fairly accurately...

Buy some TrailBoss powder, contact company for loading instructions and go from there.

Have you considered a more standard load with lighter weight bullets? That's how I started and then never found recoil an issue. My fav load is 74 gr RL15 over CCI LR (not mag) primers and a 270 gr TSX. Have never had a need for more than that in the 375.

i loaded some 235 grain speers with 21gr of trail boss. hadn't had a chance to shoot em yet. According to reloading data, should get about 1200 fps or so. I'll report back when i get em in the gun

i also reloaded some 235's with 69 grains of reloader 15. hadn't had a chance to shoot them either. Should be a great whitetail load

3/4 the listed charge of H4895.

Try Lyman 375448 (solid or HP) and 35 hrs. of Reloader 7 for starters. I use it for whitetails and hogs as well as Lyman 375449 with the same load. 15-16 grs. of any medium burning pistol or shotgun powder will work as well. Approximates 38-55 power. Good for 1" to 2" multi-shot groups. Shoot them as cast and tumble lubed in generic white lube. I use 300 grs bullets for serious work over 77 grs. of 4350. Sighted in at 2and1/2 inches high at 100 yards it on out to 325 yards with the same trajectory as 180 grain slugs in my 30-06. Will handle anything in North America and most other places on this Earth

I have used 260 gr. Cast Performance .379" FNGC originally designed for the 38-55 with 30gr of IMR4198. You can find this in the Lyman #49 Handbook (or Loaddata.com). Chrono's about 1550 FPS out of my Rem700 with a 24" barrel . Makes for a great plinker load, wanting to try it on whitetails this year.

Bingo; can even go down to 60%

An acquaintance of mine has a 375 H&H in a Voere. Plenty nice rifle, but he is a 145 pound slender, non muscular type, that thinks he needs 4500 ft pounds of energy to kill a moose. The recoil of the 260, 270, and 300 grainers was way too severe for this man, so I initially told him to buy a 308, and he said no.

I did a bit of research and came up with a load of 56.0 grains of IMR3031, a LR primer (Winchester) and a Hornady 225 SP bullet. It recoils like a stiff 30-06 now, which I believe is still too much for this guy, but he won't listen. I was able to get two rounds touching and one just beside it at 100 yards, but his "pattern" looked like an eight and a half by eleven inch piece of paper.

I think if you want a lighter recoiling round, a lighter bullet and a faster burning powder (lighter charge weight) is the answer. It works.

40 gr sr4759 with hornady 220 fn 215 federal primer. This load cronied at 1800 fps and is very accurate

One of my favorite "light" loads fr the 375 H&H is 68g rains of Reloader 15 and a 260 grain Nosler Accubond. In my rifle this provides 2650fps. Not quite a 75% load, but just enough reduction to keep the shooting of multiple rounds fun.
