Doug, those look like pretty darned good patterns to me! What shells were you using?
Joe- I don't know how good the patterns are but I noticed when I got a clay up close, it pounded it hard, and I found that if I missed with the first shot, more often than not I managed to break the clay with the second shot and some of those second shots were at a pretty good distance.
So far I have shot 175 rounds through the shotgun and the only ammunition I have used is the Federal Vintage Gold Medal Ammunition 12 Gauge 2-3/4" 7/8 oz #7-1/2.
"This vintage ammunition was produced specifically for MidwayUSA to the following specifications:
7/8 oz shot, 1200 feet per second velocity, 5,000 pounds of chamber pressure."
Midway cautions it is not for use in damascus barrels, however.
So essentially, I am shooting an 8 1/4 pound 20 gauge, and loving every minute of it!
