Just curious, why not a 308 for heavier bullets if you like heavier bullets on larger game. I think 7mm is fine and I'm no expert but wouldn't you have more mag room for 30 caliber bullets?
I guess I don't understand how a 308 has more "mag room" than a 7-08 in the same rifle?
As to bullets, 150/7mm-08 will do everything a 165 will do in a 308, and I'm also certain a 160/7mm-08 will do everything (and more) a 180 will do in a 308.
I can't believe I'm defending the 7-08.
