Just a reminder that the honorable .375 H&H can easily be "cleaned up" to the AI version, making it the equivalent of a .375 Wby. Still, H&H ammo can be used, if needed for Improving cartridges or in a pinch. So, a question: does that still make it inferior to the "magic" of a shorter throw from the Ruger? I've read quite a bit on this debate, but never yet on comparing any advantage of a .375 Ruger over a .375 Wby or AI.
Just some of my preliminary thoughts when I picked up my .375 H&H a year ago this month. I may yet have it AI'd. I've lots of new-unfired brass.
Yes, I know that could possibly (in theory) slow reaction times down a little for a second, third shot due to more recoil, etc. But so far, no one has ventured into a debate of any real advantage of a .375 Ruger over a .375 Wby when facing "danger in the tall grass" or bush! Why? Perceptions perhaps?

Why do a .375 H&H-AI when the .375 WbyMag has all the bugs worked out of it ?
The .375 WbyMag came first, and is now the best.
The .375 Weatherby Magnum existed as a Weatherby wildcat since 1945, long-throated.
It got a long-throated CIP homologation in 1987, then sometime after 2002,
when Weatherby revived it for resumption of factory production,
it got a throat proportionally similar to the 6.5 Creedmoor.
My Dave Manson reamer drawing from circa 2003 is specified to be according to CIP.
Parallel-sided throat length is 0.370" and diameter is 0.3756", just .0006" greater than bullet diameter.
Leade angle is 1*07'00".
CIP MAP is 4400 bar (63,800 psi) for the .375 Weatherby Magnum.
Compare that to 4300 bar (62,350 psi) for the .375 H&H Magnum.
Also, if you fire factory .375 H&H ammo in a .375 WbyMag chamber you slow it down about 100 fps and make it gentler in recoil.
Hunt with it while fire-forming brass.
My favorite .375 WbyMag shoots 0.8" for three shots at 100 yards when doing that with Remington factory ammo.
Or get the excellent Norma-made, properly head-stamped brass and gain more than 4 grains water gross capacity
compared to the W-W, R-P and Hornady brass makes.
The .375 WbyMag is my #2 favorite cartridge after the #1 .458 WinMag.
It definitely beats the .375 Ruger except for the extra 0.2" length of bolt throw.
Somehow, Hal Waugh survived decades of "Fair Chase" in Alaska as a PH,
despite his preference for an M70 .375 H&H re-chambered to the .375 WbyMag.
He called her Big Nan.
He must have had nine lives.
