Lots of buckshot available at the last gunshow in Wichita. I haven't been to The Great Wal-Mart of China for about a month, so I don't know what they have. I have a goodly supply of 12 and 20 gauge, and while loading 2 1/2" brass shells for an old 28 gauge I bought, I loaded a few #4 buck shells. That might seem puny, but 16 pellets is nothing to sneeze at, and my wife can handle the gun easily.
