Can anyone suggest moderate loads for this cartridge, suitable for whitetail, hogs, and generally getting familiar with a new rifle? (Yes, I've got a similar question on the .338 on the "Medium Bores" forum.)

From several manuals and Ken Waters articles I see quite a few using the 235-gr. Speer or 225 Hornady SPs, loaded with IMR 4064, 3031 and either brand of 4895, at about 2500 fps.

I could also go for lighter loads (.375 Win. equivalent) with the 220-gr. Hornady or 200-gr. Sierra (both flat point) and SR 4759 or AA 5744 for about 2200 fps.

What have you tried and what worked best?

John,

Mike375 is the guru on all aspects to do with the .375 H&H. I got a starting load of 39.0gn of AR2205 (I believe this is marketed by Hodgdon as H4227 but please check) with the 220gn Hornady Flat Point, WW cases & WLR primer.

Very pleasant to shoot. I have worked up a grain at a time to 42gn of AR2205 chronographed at 2200fps. I've stopped here because it hits dead on at 100 yards whereas my full power load hits 2 1/2 high at 100.

I don't think I need or want more speed. Accuracy was excellent.

Good Luck,
JohnT

PS. we can't get SR4759 powder at a reasonable price in Australia but that powder was formulated with reduced loads in mind. Speer Manual has reduced load data for this powder.

A couple of loads but also unfortunately using ADI (Aust Defence Industries) powder. One is similar to JohnT's load

.375 H&H Magnum
AR2205 - 36 grs - 220 gr Taipan or Hornady flat point 2050 fps - similar to the 375 Winchester

AR2208 - 65 gr - 220 gr flat point 2500 fps - a lighter load than full power

John F,
ADI's AR2208 is sold by Hodgdon (spelling???) as Varget.
Cheers...

2205 is H4227 Extreme

John,

I am sure if you try 38 grains of H4227 or IMR 4227 with 220 grainers in the 375 you will find the pressure to be very low.

Around the 35 grain mark and you will have sooty cases and the bullet will bea press fit back into a fired case.

Guys,

What sort of accuracy are you getting with the 220 Hornady and the 235 Speer and at about what velocities.

How much "down load" does it make sense to go with these two projectiles for deer hunting ... in other words, how fast do they have to be moving to expand?

Looks like I'll get to take a .375 into the field for the first time this year ... and it'd be very helpful to get the loading and testing done before bow season starts in Mid-October.

Thanks!

The 220 Hornady was designed for the 375 Winchester and that tops out at about 2200 fps. I shot a couple of hogs with the 375 Winchester one at 10 feet and one at 100 yrds and both of them exited. I've loaded them in my H&H to 2,500 with groups about 1" at 100 yrds. Shot one 150 lb. hog on the shoulder at 60 yrds with this load and the bullet exited the other side easily.

I do most of my hog and deer hunting with 300 gr Hornady RN loaded to 2,600.

I use the Lyman .375449GC cast of wheelweights and shot with 60 grains of H4831. It gives about 1900 FPS, recoils like a .30/'06, is a great practice load and works well on whitetails out to 150 yards!
