I'm shooting 68, 70 and 80 grain Bergers along with 75 grain A-Max and 80 grain SMKs.Best shooting bullet to date is the 75 grain A-Max.
Oh yeah! Now there's a man that knows how to treat a .223!

Don't know why all these guys want to shoot those 52g "girly bullets". Anything less than a 69g bullet in a .223 is a waste of powder. ;D
