I use black
powder and fuse only, and the 'most fun charge' is one ounce of ffg black,
and a twelve ounce sinker with wads. So far, the furthest it has fired at
the range out in the desert where you can see the dust, is around 800 yards,
but I didn't have the barrel pointed that far up for elevation!! Golf balls
are fun, using fffg black, they really sail! My best guess is around 400
yards. Too much powder and the golf balls blow up!!
