Here are 2 new old hex head plug i just modified this morning to reliably ignite BH209. They will be mailed to 2 happy shooters this week










They have been modified to a design extensively tested to ignite BH in all kinda weather and/or conditions. Note the flame channel is enlarged to 5/32". The powder end is drilled and tapped to receive a vent liner. When the powder end was being worked for the vent liner, a small powder chamber was also created. These vent liner have 0.028" flash hole, thus will be good for a couple hundred shots or so, before their flash hole grows to 0.035".
