Jon, I really do not remember that at all. I know I have always suggested that you need/should use new FPJ's especially in the hunting situations shooting BH.

And Tom's suggestion or comparison of the convex vs. the concave plug is also valid. The convex plug was designed to reduce blow back and the flash hole was reduced in size to help with this effort. That reduction of size hole in combination of the size of the flash channel in that plug would lead to problems. But as stated these plugs existed long before BH was thought of.

But with all of this what has that got to do with the CVA problem, which I really do believe is not going to be limited to this one ML. And one picture that really puzzles me is the one that chaded pointed out - why is the top of the receiver getting shipped...



This would kind of concern me in a new break open... Is closing the barrel causing this damage???
