factory flush mount

[tha bugman]

anyone done any pattern testing with the factory flush full choke in an sp-10?  if so what were the results?

I tried it once and it was awful. I think it is like a .725 if I remember correctly.

A friend of mine did a fair amount of patterning with his and got good patterns to a little over 40 yards. Just expect normal full choke patterns, not too tight but nice and even. He was getting his best patterns with Premium 2 1/4 oz. #4's. Did better than XX 2 1/4 oz. 5's. Try it and see what you get.
