This season I used a 16X65 hammer double with cylinder and full chokes. With 28 grams of #5 Bi-Sn shot the cylinder barrel accounted for as many ducks as the full choke barrel. The gun has long barrels, 80+ cm, which always in my experience gives much better patterns with cylinder choke than do short barrels.

Also shot 16 yard trap with this cylinder barrel, with 27 grams USA 7,5 shot, and broke targets reqularily so long as I shot a little sooner than usual.
