I have a friend who just purchased a 300wsm Browning A bolt. He will be deer hunting with it in east TN. He asked me about what ammo to shoot, I don't have a clue for this cannon. Anyone have a suggestion on what factory ammo and what grain might be the best most accurate round. I told him Hornady was pretty good for factory ammo but did not know about what grain bullet to shoot. This guy is a huge deer hunter but always bow hunts. He is going to try some gun hunts for the first time. I cant help him out because all I own is a .223 and a 22 hornet and im just learning about those. Thanks for any help.
