hp ,, thanks for reply ,, I have a older Lyman 457122HP ,it measures OAL @ .905 , the grove is @ .420 from base, leaves a grove to tip of nose @ .485, it cast @ .458-.459 w/ my mix I get .343gns. + .3-5gns. ( call it .350gns. ). 2.70 - 2.80 will feed w/o any problems , the question really has to do with , shorter case length & pressure . Yes I can use less powder ( smokeless ), was wondering if anyone may have tried the shorter brass & chrono'd their results.
I do like the looks of the Accurate # 46-305c , thanks for the tip ( just now i'm out of alum cans , loading money ). I'v been rebuilding this o'l ( Chappie x 26" call'r " PATCH'S " ) rifle and now it's time to get it accurate ,, diff powders & case OAL.
