I have, but I believe sniper300 does not and gets very good consistent results. I would try without bedding first. It will not hurt a thing, and might save you some time. If it doesn't work so good, then bed it.
Well i had a non bedded Rem 700 308 in an AI chassis and it was a1/2" rifle. Im jst wondering this rifle is a different animal with that much of a caliber difference.
