I'd forgotten how well those 465's shot from the GM Renegade until I went back and looked through my old target file. I suspect they will do even better from that 1:20 twist.

Here's an interesting one of the old targets with the gun sighted in to be 1.5" high at 100 yards, and two shots each at 50, 75, 100, 125 and 150 yards using the same point of aim for all shots.
