8" round plate at 100 yards. GoPro vid is awesome, but it's hard to even see this target in this vid. Those posts you see on the foreground are from the 25-yard setup on paper.
I forgot to bring paint, and this steel was already shot, so I couldn't measure any kind of group size based on impacts. Too hard to determine what was an old impact versus a new impact, so I didn't even bother. It connected, though, and really well. I need to get the magnified optic for this thing, and get it out again, before I can say what size groups it shoots. I can't measure it alone on irons. I can say that it's not shooting bad, not in the least. It's shooting pretty good.
