As you proable noticed a while back Sabotloader and I have been experimenting with using a modification that puts a vent liner in a used up breach plug. I have been puting mine at the end of TC plugs because thats where they put the touch hole and it has work well. Sabotloader likes to inset his and as far as I know this is working well for him, it might also be something for you to check into. Lee
