The .366 caliber cartridges are excellent!!! I love my .375 H&H and the .375 Flanged Magnum, but I love them no more (nor less than) the 9.3 x74R...... They are all excellent hunting cartridges, but I still prefer to step up just a little in power for DG hunting. Call me what you will, but I’d rather pile on a bit more power and be accused of “compensating for something”, rather than being stomped and gored into a puddle of bloody mud by a pissed off big dangerous animal.
