Thanks, Jay for the explanation. I’m active on the ML forum as flintsteel. Guess I’m skeptical but willing to see something new. I’d think a heavy fiber wad over the shot would tear the pattern to pieces. Anxious to hear what your experience is.
Your Manton was designed to be self priming. Of course it was before these huge personal liability awards but it works fine and really speeds ignition. Close frizzen and load with something like 3f and when pushing down the wad escaping air pressure will fill the pan to perfection. I’d reduce the powder charge by about 20% to start and then work back up if desired. I own a Manton target pistol with the same self priming feature. I load a 9mm case with 4f and load normally. The pan fills as much as Manton desired and ignition is almost instantaneous.
Am reading a biography of John Adams and just last night read that at the 1776 Continental Congress John Hancock always kept a silk handkerchief wrapped around his right hand. Some years before in a hunting accident he blew off all fingers. Wonder what he was doing…..ha!
Be careful, it’s a dangerous world out there!
Here is my Hege Manton lock clearly showing the self priming feature and the division on the bottom of the pan insures powder will be evenly distributed on each side. Very inconvenient to prime externally.
