Ammoguide.com lists 175 loads for the .375 H&H, eight of them with N-150.Right then.
Cheers guys, seems the concsensus is broadly magnum then. Good to know, I've got loads of them!
Does anyone have any experience with N150? THe Viht data is a bit anaemic versus every other source I've seen and I'd rather not waste 20 odd shots working up from the bottom of their ladder if they're starting at 2,100fps or whatever.
not necessarily, but possibly.
worst case scenario, in a really big case with slow burning powder it could produce a secondary explosion effect and blow your gun up.
CBHpossibly where the first advantage for mags will be noticed is in really cold conditions with powder 4350 and slower.
it is said that win ball powder can need hotter primers than say imr stick powder, and that win primers reflect this.
