Sold my 10 gauge Darne R-16. But I've kept a Lefever C 10 gauge thumb-push with 2-7/8" chambers. The gun has two barrels, but weighs 8 lbs or more no matter which set of barrels is attached. Bought a number of Federal primed 10 gauge 3-inch hulls and cut them down. Also use Longshot and load with either 1-1/4 oz of #2 Bismuth or Nice shot. Shoot geese across Chesapeake Bay near Chestertown, MD on the Atlantic flyway. No more ducks there anymore, unfortunately.

Best of the Season, Tim
