Area: Wyoming. I’m just gonna offer an “unqualified” comment! The average hunter, is not like the majority of “gun-nuts”, like us on “the fire”. So my answer would be.....they primarily use one rifle/cartridge for all of their hunting! So, listed in no particular order......270 Win., 30-06 Springfield, 7 Mag, and the .300 WM. Likely, the 270 and the 30-06, would top the list! memtb
