Home Forums Reloading Big Game Rifles Factory .375 HH Mag ammo for Moose?

I find it hard to imagine a factory load .375 H&H that is not appropriate for hunting moose, unless it is a non-expanding solid bullet. Moose are "normal" not exotic game around here, and most would hunt moose with much smaller cartridges. .270, .303. .308 7mm mag, etc. Most any currently available expanding bullet .375 load will penetrate adequately, expand enough, and kill effectively. I've based my opinion on a few elk I've taken with the .375, but moose are not much different. The only moose that I have shot with a .375H&H was taken very efficiently at just over 300 long steps, with a very inappropriate bullet - the old style blue box 300 gr. RN factory load, by Federal. To read internet comments about the old cup and core round nose I may as well have been throwing rocks. But full penetration, good expansion, and a 20M death dash says otherwise. My brother has taken a few moose with .375 lightweight bullets, 235 gr. TSX and Speer. No complaints.
My advice, avoid the extreme heavy/tough bullets and the light/fragile bullets. Anything else will work very well.

You are correct I appreciate all the insight and comments. Midway will be delivered tomorrow and just waiting on my brass then I will begin my load testing. I was also worried about the scope rings and bases. They are all red Loctite and torqued to the proper inch pounds. I just decided to upgrade the scope to a new Leupold 5hd-2-10x42. I was figuring I did not need any more power then that by stepping up to a 12 or 15.

Not H&H, but my .375 Ruger shooting the 270 gr. TSX has been lights out on a Kodiak Bear and 2 A-Y moose. I would never use anything else.

Nothing wrong with Remington or Hornady 270 grain, if your rifle shoots it. Moose are not hard to kill, it just takes them a while to know they are dead.

Shot my bull moose with a .340 Wby and 250gr Partitions. The bull may have gone 3-4 feet, it was had to tell at 165 yds.

At the time I didn't have a .375 H&H, but now on my 3rd - relatively new since February '23 - I've shot a lot of different handloads through it's 22" barrel, including 235 TSX's, 250gr Sierras, 250gr TTSX's, 200gr and 250gr Hornadys, 270 TSX and 300 TSX.

I've settled on the 250gr TTSX at 2850 fps from 77 grs of CFE 223, WLRM primers and new Rem brass. It shoots 3 into MOA or better when I do my part. It's sighted dead on at 50 and 100 for backup to my .458 in a couple weeks for a bear.

I shoot 80 grains of CFE223 in my 375 H&H, Winchester cases. Federal 215 primer and I get 2806 FPS

For many years my primary rifle was a 375 H&H pr64 SG and I took something close to a couple dozen moose with it with various bullets but the 300 TBBC became my favorite. Having gotten older and needing a scoped rifle, I moved to lighter calibers and rifles......300 WSM & 9.3x62. Judging from the performance I've gotten with the Barnes TSX with those rifles, I'd move in that direction with a 375 also.

And if you want to try those 270s w/ Varget....

Factory load data:

• Barnes: 73.5 @ 2,715fps
• Hornady: 75.1 @ ~2700fps
• Speer: 67.0 @ 2,549fps (seems like an outlier?)

270TSX, 3.595"oal, Varget, Norma brass, Fed215m
grains / fps / 3shot group

• 69.0 2660 3/4"
• 69.5 2690 1.5"

69.0 has shot so well for me, I didn't see the need to add more.

Barnes' max velocity of 2,715fps seems like a good place to stop; 70 would probably get you there.
