Lattin1 Posted May 7, 2015 Report Share Posted May 7, 2015 So I've got A-Max 208gr. bullets and Burger 220 gr. bullets. Figure thats enough mass to create the back pressure needed to cycle the carrier. Now I just need to know what powder and how much. Also, what primers to use and OAL. Anybody know this stuff or have a link to this kind of info? Quote Link to comment Share on other sites More sharing options...
