Outstanding and it satisfies someone's need for a special rifle.Is the hammer in the fired position or is it JUST off the nipple?
If it's in the fired position I would deepen the cup so it would help with possible cap flash.I have made only ONE of the correct
style locks for this style of rifle and it was a right and left pair for a double rifle.With no proper breech it would be no benefit and
a good job was done with what was available.
