I've been shooting a 700AS for over ten years now. I've tried alot of different loads thru mine and have settled on the 160 Nosler Partition being pushed with IMR 4895. Excellent groups off the bench and hits like a hammer. Never seemed to get anything else to group near as well, but that's my rifle. Tried loading the second gen 140 Nosler BT for deer. Bullets were blowing apart because of the velosity. Nosler ended up sending me a couple hundred third gen bullets to try but I just loaded them in the '08 instead. The 160 just seems to work best for me.
