I got my testing of the plug done this morning. I'm only going to recommend a few changes. The flame channel to be drilled out to 5/32 like the Savage plug. And the vent-liner to be brazed in the plug so it cant be removed. And also make a FPJ version as well.

I shot the plug 25 times today. 140grns of BH209 and 150grn bullets in my 45cal Knight Elite. This plug is really clean and NO blow back at all on my scope. I put a piece of white cloth around the scope to check this. I will post more pics later when i take the plug out of the gun.

Here are pics after 25 shots.
