Had a nice 375 H&H Model 70, and sold it:
It had a Douglas barrel, pretty danged nice stock, custom scope mounts set up for Talley QR rings, etc... Great rifle, but I just wasn't using it, so off it went.
These days i still have a 375 H&H Ruger Number One, with which I've shot three black bears.
It worked just great using the 260 gr Noser Accubond at about 2650 fps.
Love a good 375 H&H rifle! I think the OP is in for a world of great shooting and hunting with his.
Regards, Guy
