The range of opinions on recoil of a 1B in .375 H&H should give a warning to the OP as to whether or not it's the cartridge/rifle combination he's looking for; I have a feeling he may not be that experienced with rifles or with game animals.
There's a LOT of that on this board. A lot of crap gets repeated and regurgitated, a lot of basic facts ignored, a lot of basic common sense cast aside, etc.
