Mike,
On My ACCURA's BP the end is kind of Concave and Flat...half of the outside diameter of the BP is flat the inner half of the BP is Concave. Did they make it this way to serve both pourposes of using lose powder and pellets? So if Im using lose powder a concave is better and pellets a flat end is better?
Along with drilling out my Fire Channel on My ACCURA's BP should I add more of a concave end to what's already there?
