They reply fast but don’t give the best answers. They said I could not run a 7 SAUM but could run a 7 WSM. The WSM is higher pressure, uncorking pressure, and pill speed, after relaying this info they said. We can’t tell you that you can shoot anything with the word ultra mag through it. So idk how much I actually trust their answers. Find someone with QL and have them compare the round you want to one that it is approved for and go from there.
