762 ULTRAMAGA
WKR
I have like 5000 142 SMKs so that's what I'll be sticking with, I could shoot some 147s for groups and velocity cuz I have a few boxes on hand.Any chance you're going to try the heavies (153 A-Tips or 153.5 Bergers) in them?
I'm not opposed to testing some 153s for the data though
