RE: 308 for moose
Your right but the only problem is that the average hunter won' t be able to find a lot of those cartriges in their local stores. Like the 8mm-06, 338-06, 35Whelen, 348 and 358 Win. The first three are by far the easiest to get.
I would also have to include the 7mm-08. 280 Rem.,284 Win., and the 308 in there too as being sub 30-06 cartriges. Don' t forget the .444 Marlin in the big bores.
