As HankPage said, the pattern is very different in a Public Defender. From a 2" barrel Public Defender, PDX1 will spread to a 12" diameter cloud of BBs at 7 yards. I didn't specifically try 10 yards, but I'd guess that it'd probably be on the order of 18" in diameter at that range.Interesting! Your 10-yard PDX1's shot pattern is much tighter than I've been lead to believe.
In my experience, the Federal buckshot is always way, way, way, way, way tighter than the BB spray from the PDX1. I've tried 2.5" PDX1, 2.5" Fed 000, 3" PDX1, 3" Fed 000, from an RJM and a Public Defender, and the Fed 000 always groups very tightly and hits like you'd want a shotgun to hit -- a big slam of force all in a tight group with multiple wound channels. The PDX1 defensive discs hit pretty similarly, but the BBs are a quickly-dissipating cloud that spreads very wide. You can almost keep the BBs on a man-sized target from 7 yards, but only if you aim and hit absolute dead center of mass. If you're off to the side at all, some of the BBs are going to miss the target completely.Diameter-wise, how does the PDX1's discs/BBs pattern verse the the Fed Handgun's buckshot at whatever the longest distance is you shot both?
I like it in 12ga. It has a one ounce rifled slug and three steel 00 Buck pellets. That should stop an intruder late at night!What else have you tried it in? For most rounds it's a normal but very effective hollowpoint, but the 410 is just a really unique load. Have you seen the 12-gauge? Looks like they have two different loads -- one was a slug followed up by three buck balls (sort of similar to the 410) and the other load is a segmented slug that hits as one projectile and then breaks into three pieces to make individual wound tracks.
