Took out my remounted Encore ML barrel. Decided to try Hornady Bore driver with 110 GR Blackhorn 209. I fired a few caps and some loose powder through prior to loading. I did get to fire, but was getting some blast on firing near breech plug, then about a 1/2 to 1 second delay prior to going off. Breech plug hole seems really small, but a few sparks exit barrel on firing just. So i gave up sight in. Any thoughts???
