CZ,
I am sure I can adjust the stock however 4" at 16 yards is not OK in my book. As Stan says, it needs to shoot exactly where I am looking. No matter how you shake it, the barrels are *" apart at 16 yards. I tried 35 yards and it did seem to be further however I needed tighter chokes to make sense of it. I had left them home.

So many guns, so little time!
