Lightest possible loads for .375H&H?

[PJgunner]

My pet load for my Ruger 31 in .375 H&H is the RCBS #37-250-FN cast bullet, 49.0 gr. of IMR-4895 for an estimated velocity of about 1900 FPS. I never got around to running them through my chronograph. Recoil is about in the range of a stiff 30-06 load in that rifle. Groups run in the 1.25 to 1.50" range at 100 yards.
FWIW, factory loads in the .375 H&H ain't all that bad. If you've ever shot magnum duck or goose loads in the average 12 gauge shotgun, the recoil is about the same.
I have been known to shoot pocket gophers with a .375 H&H using the 300 gr. Silvertip Winchester ammo. I'd just bought the rifle, a MarkX Mauser and used the loads to get used to the rifle. I went through five boxes before I felt that the rifle was good to go. I'd planned on using it to hunt elk. I sold it later on when I got into the single shot frame of mind I'm now in and now shoot the #1 in that caliber.
