I would like to thank everyone who answered my post, and to Rickky for posting the link. A lot of pro's and con's to be considered, and I'll probably never shoot near the number of rounds in the test, but the thought of doing more damage to my weapon by going with cheaper steel rounds is hard for me to get past. Truthfully, I am not using an automatic rifle, but rather a bolt action rifle with a 4-16 scope, more (least in my mind) a hunting or sniper rifle. It's a Weatherby Vanguard series 2 in .308, not a top of a line rifle, but Weatherby prides itself in sub MOA shooting rifles, and the one I have seems to hold true to that statement. I'd like to keep it that way, I am leaning towards staying will brass ammo. Thanks again for taking time to respond. -dave-
