The only flaws I found were in the hand and bolt, which both had casting flaws, but performance was not hindered. Timing is dead nuts on. I benched it yesterday and the results were a nice grouping at 15 yds. , but it was about 10 in. high and possibly a few inches to the left. However, the windage could have been me as the sighting plane is abyssmal, as all cap 'n balls! I need to either install a taller front brass bead or have a buddy mill a dovetail slot. I think the gun is a shooter and the only binding was caused by fouling on both sides of the hammer, so I relieved, i.e, polished, the sides of the hammer that enters the firing channel.
