killed my first elk with a 7mm @240 yards, big animals can suck up a lot, 3 160 grain nosler part. and he was done. bought a 300 win mag for next hunt. I have weartherby mag and I do not recommend them mainly for cost of ammo, even if you reload the brass is expensive. a 300 win mag or 300wsm would be my first choices, anything larger and they are not much fun to shoot. I am not recoil sensitive, you do not notice when hunting but sighting in is a different story. every gun I own had to try numerous weights and brands to get tightest groups. your 308 will do fine, go with a heavier bullet and limit your shots to 250 or less. hunting Colorado with friends for deer and elk most were shot at 200 yards or less. doubt if you are going to shoot like on Best of the WEST. good luck, you will be hooked after your first trip. wait till after to decide if you want or need another gun, of course I tell my wife a man can not have to many guns.
