Happy New Year gents!
It’s been a long while since I’ve dipped my toes into the muddy waters of the .404 vs .375 debate, and every time I do it seems like the same things are getting thrashed out and the same things are getting left out or misunderstood. Let me say up front I have both a.375 H&H and a .404 Jeffery, but do like the .404 better. Perhaps it can be explained by cognitive-dissonance theory, as it cost much more than the .375.
Everyone has their theories as to which is best and why. Here are mine: first, the .375 H&H became available in the US in the Winchester model 70 pre WW 2, along with the .300 H&H. Both of which took 4 down at that time. A relatively inexpensive rifle made in the USA, with Elmer Keith touting it as the perfect elk rifle, it naturally got a lot of press in the gunzines. For years.
Not so the .404. No one wrote much about it in the states other than the very occasional article in Guns and Ammo by Tom Siatos or similar.
The perpetual drum beating for the .375 inspired new projectiles, new powders and higher velocities than when it first came out. Meanwhile, the .404 limped along on the anemic British loading of a 400 grain bullet over enough cordite to get up to 2,150 fps, generating 4,000 ft pounds. Not much to brag about. Heck, my .338 Winchester, my 9.3x62, and my 300 Weatherby can all be loaded to generate 4,000 ft lbs at the muzzle. That single anemic British loading was all most of us ever knew about the .404.
On the continent, the 404 was listed (at least by Mauser) as the 10.75x73 Eley. The 400 grain load put out by DWM was loaded over flake powder and produced a velocity of 2,350 fps, for a muzzle energy of 4,906 ft lbs. Quite a bit stouter than the anemic British loading, But no one over here had ever heard of it. (The Hornady factory load is essentially the same thing, 90 or so years later.)
Accuracy in a well made rifle in either caliber is the same, depending on the shooter’s skill. Most of us could use more time behind the gun than behind the lap top.
Weight of the two is essentially the same, though most 404s are built heavier due to wieners at their controls. If the gun fits you, and you practice with it, either will do what you want. If you’re looking for a rifle to shoot antelope way out there, why take either? Want something unique? Then put together an 8x68 - faster than either the .375 or .404.
If you’re worried about charging buffalo or whatever, reread Bell on his Buffalo experiences.
As Bell discovered, the key isn’t the foot pounds, it’s the placement of them that counts.
