The primers shot in the patriot rifle were leaking a lot of soot right through. Being how this bothered the shooter a lot, a fix was sought.
The primer sat right on a 0.035" flash hole, or/and a 0.039" flash hole depending on the plug. This seemed to be too large and/or too close. This flash hole was drilled out to 5/32" which then became a short 5/32" flame channel. The powder end of the plug was drilled, and tapped so a hollow lock nut could be installed. A 0.375" long x 1/4" diameter tungsten carbide bushing was placed into the plug, and locked in place with hollow lock nut.
Photo shows the fouled plug after six shots this morning.
Another issue was the head space provided by the breech plug was so large, much blow by went around the primers. Beings how this bothered the shooter a lot, a fix was sought. A simple, perhaps temporary, solution was the addition of an o-ring into the primer socket; seen in the photo.
The six primers shot this morning.
The Woodman Arms Patriot rifle was loaded, and shot with 95 grain Blackhorn powder, poly wad, 265g Fury STB bullet, Federal 209A primer six times this morning.
