I created some slow motion videos of the Brocock Bantam/Compatto Hammer to see what hammer bounce looks like. The Brococks have a great side window to see what is going on with the hammer. The videos are with no pellet, so there may be a bit less bounce with a pellet. I will need a better setup to safely try this. Hopefully you can see these ok, as I marked them unlisted. I will work on slowing them down further this weekend.
