**** UPDATE ****

I made it out to the range to pattern the 16ga shotgun barrel. I loaded a 3-dram load of 1oz of 7-1/2 = 338 pellets. The shotgun choke of this barrel measured .005", which is a SKEET choke. A skeet choke is recommended for close dove and woodcock hunting. Target is shown. With this result using shot, and the result using ball, and using the rifle, I'd be happy to take this gun into the field and test it on any size game, from dove, to deer, to boar or bear.
