Hello James B. I am very curious in regards to your numbers. Are these numbers with the same bullet weight? My experience with these two is that the 338 Kicks like hell and the 375 is more a shove. Is this my imagination? The 338 I had was on a Sako L61R action while my 375 is on the Sako AV action which is a bit heavier. Kick or no kick, I consider the 375 H&H to be one of the best of the best calibers for big critters and so do others with far more credentials than me....to point:

"As much as I like the .375, I have never seen much use for it in North America, except for hunting the big Alaskan brown bear. However, if anyone wants to use it on elk, moose or grizzly, I am not going to take exception. It is a hard-hitting, flat-shooting cartridge, for which I have scored a higher percentage of one-shot, in-the-tracks kills on medium to large soft-skinned game than with any other cartridge." -- Jack O'Connor, The Complete Book of Rifles and Shotguns, Outdoor Life (1961).

"THE .375 H&H MAGNUM
But the queen of the medium bores is the .375 H&H Magnum, one of the world's most useful and widely distributed cartridges, and probably the best all-around cartridge ever devised." -- Jack O'Connor, The Complete Book of Rifles and Shotguns, Outdoor Life (1961).

"For an octogenarian, the .375 Holland & Holland Magnum gets around right well. Other cartridges are decidely superior for most any specific big-game hunting assignment. But if you balance lethality against ranging capability, and factor in tolerable recoil, the .375 H&H (a.k.a. .375 Belted Rimless Magnum and .375 Belted Rimless Nitro Express) does more jobs better than any single round we have. It is arguably the most broadly effective cartridge in the entire history of sporting firearms. If internationally experienced hunters were asked to vote on one cartridge for all-around use, the .375 would win by a landslide." -- G. Sitton, "Reloads: The .375 H&H Magnum," Petersen's Big Book of Cartridges, Vol. 1, p. 84.

"The caliber .375 H&H Magnum is....a wonderful cartidge for use on elk, moose, bear, or the heavy artic game. In a factory make rifle and load, the .375 H&H Magnum in the Model 70 Winchester, Model 700 Remington, the
Browing, Sako, etc., is one of the finest all around rifles and cartridges." -- Elmer Keith, Hunting Big Game, Peterson Publishing Company (1965), Chapter Two, "Timber And All Around Rifles," pp. 37-38.

or.........
"f I could have two cartridges to hunt the world, I'd be quite happy with the .30-06 and the .375 H&H. And if I could have just one cartridge to hunt the world over, my only answer is the .375." -- Craig Boddington, "Classic Hunting Cartridges: .375 Holland & Holland Magnum," Petersen's HUNTING, June 1995, p. 43 (emphasis in original).

Now that's some heavy stuff from some of the heavyweights of all time. I'll stick with my post irrespective of the extra 2 pounds or so recoil. Regards, Rick.
