I shoot IMR7625, 1 oz and federal gold medal hulls for informal blasting with this gun. I may still shoot federal paper, uni wad and 1 1/8 oz for another clays shoot comming up in which I won 2 years ago with this load giving me 1200 FPS and about 5000 PSI. I am down to my last bag of UNI wads though and when they are gone, then no more.
