Having some issues loading for my 6.5 AR10. Loading ammo to 2.800 COAL, I have a criterion barrel that simply will not chamber All the way with my reloads. It used to fine but now it doesn’t. I suspect my die is not sizing the brass down enough, as factory ammunition chambered fine.
All the rounds fit in my delta 5 pro but they won’t chamber the last .10 inches of the case in my AR10. They get stuck to the point I have to actually pry the bolt back with something to get it unstuck if they don’t fire. If fired they extract fine. Also the brass looks scratched up tremendously.
I’m using hornady match grade 6.5 dies. I had not had this problem with my other 18 inch barrel from criterion, I even sent this barrel in to see if it maybe needed to be reamed out a little more and they said it was within tolerance. Headspaced, bedded it and gave me a free bolt. I ran 5 rounds through it after I returned from the range of standard hornady 140gr BTHP and it cycled fine working the charging handle which leads me to believe my dies aren’t sizing correctly. Anything else I can do to check? Magazines were fine and the COAL was good on all rounds
