Good idea on the Colt bullets. I have been sizing down some Lee 405 grain RNFP from a mould that drops at about .455” or so. I size down to .453” and patch up to .4595” or so.
Then I pretty much load them out as far as I can and hope for the best. Should I be doing something other than this?
I have some absolutely perfect cast Lyman Postell bullets that I’m waiting to wrap. These things are falling with about 1 grain variation. I have brand new Starline brass all primed up waiting and like I said I have 5744 for powder because I’ve Heard such good things about it.
I’m thinking the only variable would be the powder charge and my poor shooting abilities. Well maybe finding the dead spot in the barrel to rest on.
