[QUOTE="mudygmc, post: 1615795, member: 57931"] My brother has a Dpms light weight hunter in 260 rem. Factory ammo I believe it was 120gr federal were fine. He loaded some berger 130s to mag length and was blowing primers at 42gr of h4350. Closer inspection showed that the bergers were jamming the rifling. Setting them back made all the difference. No more blown primers at 45gr even. I recently had a 6creed barrel built for a savage. When ordering the barrel there were two options for freebore. I don't remember the specs offhand. But say one was like .087 for most all ammo. The other was .1xx for hornady ammo. I bet you any money your jamming the bullet and switching ammo or handloading will cure the problem. To try take a Sharpe and color the bullet. Then chamber the round and remove. Odds are with hornady ammo you will have rifiling marks on the bullet. Good luck figuring it out. Hope this helps some.
