RE: Which powder should I use?
bore butter patchs for cleaning in field are fine.
the bore butter patch for a roundball are fine in summer.
bore butter will freeze in winter,i use HOPPES BLACKPOWDER PLUS in winter,no bore butter then.
as you see, we all have diffferent things that work.
whatever you use,STAY WITH SAME THING AND DO SAME THING EVERY TIME.
thats secret to getting good groups with a rb, same way ,same thing over and over.
if you use 3f geox,you have to load10/ 15% lower on charge than the 2f..like 80 grs of 2f is equal to 68/72 grs of 3f.
