I just picked up a new criterion barrel for the 284 win; shooting 180 bergers..
My loaded neck diameter w/ lapua brass is right at .312" which seems to be relatively consistent with others.
However, my fire formed brass shows a neck at .320" , so the reamer used is definitely not as tight as other custom reamers..
Question: Seems these fireformed dims will be hard on brass life.. How often should I anneal?
And more importantly, any expert opinions on accuracy with such a large neck expansion during firing?
Thanks guys!
