Will be having a 20 Beggs (32 &40 grainers in a 1-11" twist ) and the 220 Beggs (52-53 match bullets ) made and am looking for load help . The brass will be Lapua , primers probably Fed. 205 Match , and probably Sierra 20's in the 20 and Bart's 22 cal's in the 220 Beggs . Powder choice and test ranges would really be of help !!!!!
