RE: 308 WIN deer, ekl,....moose???
Do you want to be trendy, or do you want a good cartridge for a decent price. 165 grain bullets would be optimal. Buy Federal Premium's with the Sierra Gameking bullet. If handloading get the 165 grain Gameking, or the Nosler BT in 165. If you are trendy and like to spend money, then buy the more expensive bullets, but I personally do not consider them to be any better. I have shot alot of animals with my 1886 45-70 and cast bullets, I have not had any problemswith these bullets, and they are fairly inexpensive.
As far as the guides are concerned. I have found that a guide prefers a hunter who has a rifle that he knows how to shoot. Alot of people show up with magnum's that they can not shoot. I can assure you a guide prefers a hunter who can hit with a 308 over a hunter who can not handle a 300RUM. Tom.
