The Prime is thicker in the body and web compared to Hornady and the primer pockets held up well at 4 firings at med/hot loads with 140+gr bullets and H4350. I converted 200 Lapua .308 and I no longer load anything else. The brass stays very consistent in length/primer pocket tension over 10+ firings...some report 40+ firings with moderate loads. I love making things so forming the brass was fun for me. If I did not want to mess with it then Prime brass is the way to go IMO if you want cheaper than buying Norma/Nosler.
