Glad your with us Buck Board! You bet a lot of good folks post here and a lot of good knowledge . Nice to hear of another old 76 shooting. Sounds like you have a good start with your load ,that kind of group is very good in my book. If you get a chance try same load using Swiss 2ff . I have very good luck with this powder and the original Winchester 300gr. bullet over a case full ,no wad ,and about 1/8" compression home lube is 50/50 tallow and wax, in my 28" oct. barrel 45/60 wcf. Just loaded the same load but with a 296gr. soft bullet cast from an original mould @ .459 marked( 45/85*) . It is a good looking bullet. Hope to get out on the bench and do some shooting soon. Will post how the 296gr. bullet does soon!,,,,,,,,,DT
