The nexttarget was fired with Pyrodex RS. The first shot was off the paper and showed a chronograph reading of only 871 fps. I had cleaned it well with very wet patches and probably left some moisture around the breech plug. Got a 4" group with the other four shots (yes #4 & #5 are in just about the same hole).

Average velocity with Pyrodex (excluding shot #1) = 1144 fps.
