msorenso,
While I don't own a .375 RUM, I do own two .375 H&H's, a .375 Weatherby Magnum and a .378 Weatherby Magnum. In rifles of near equal weight(about 9.5 to 10.5 lbs.) shooting bullets of the same weight(300 gr.) the following is about what you can expect recoil wise.
.375 H&H Mag. at 2,530 fps. will have about 41.0 ft. lbs. of free recoil
.375 Wby. Mag. at 2,700 fps. will have about 48.0 ft. lb. of free recoil
.375 Rem. Ultra Mag. at 2,800 fps. will have about 53.0 ft. lb. of free recoil
.378 Wby. Mag. at 2,900 fps. will have about 59.0 ft. lb. of free recoil
Take into account that the .375 RUM is not selling well and may soon be dropped from the Remington line I would look to a different cartridge. Personally I feel everyone needs a .375 H&H in the safe. Excellent cartridge well noted for their accuracy. But if the H&H version doesnt float your boat then rechamber it to the .375 Weatherby(
my personal choice). The best part about the .375 Weatherby is you can still use .375 H&H ammo in it. Take about versatile. Lawdog
