I have a lehigh on its way. I figured it should have been here but no luck yet.

I have the std breech plug for my knights and power stem. I have always had awesome performance out of 777 and barnes with win209.

So with everyone modifiying thier plugs just to cater to BH209, has anyone went back and saw how these modified plugs do with thier old favorite loads with pyrodex, and 777, or even Goes, etc?
