okay guys im pretty new at this so take it easy on me, my 308 i single feed so this is never a problem but now ive got all the stuff to load for my ar and 223 bolt guns and was wondering if there is a magic number out there that you need to stay under if u want to mag feed? is it posssible to have it so i can shoot the same bullets out of both guns? winchester brass, varget,60 gr horn vmax, 60 gr sierra hp. cci 400. shooting mainly coyotes, hogs and stuff of this nature but still want it as the best acurrate as i can get it. thanks for any suggestions would be appreciated. john.
