I have used a hammer stall in the past but since the lock held in the half cock position, it never was needed.
I made a new one the other day and decided to try it out. The gun was unloaded.
With the stall in place, I brought the lock to full cock and pulled the trigger. I expected the flint to just bury into the leather and stop, but that's not what happened.
It hit and cut the leather, but the frizzen opened and the flint scraped down the leather, somehow the stall jumped off of the frizzen and I ended up with an open pan. This is not what I expected.
What are your thoughts on this?
