That’s actually promising. I know you don’t like fiddling but forget the cannelure for a sec and seat it out a bit further if it will cycle in the gun. A Lee factory crimp die doesn’t need a cannelure. Sometimes levers are real picky but usually a little forgiveness in there!
i had a 760 that was a 3 MOA turned in to a half MOA by doing this. Clip fed but hopefully you see my point.
