I did a quick polish of the barrel. Lines going straight down the barrel. Makes me wonder if they are supposed to be in there? My polishing removed some off it but you can still see it.
I don't think this is bad for a factory choke and XR #5 at 40 yards.
I am puzzled that the wod went all the way though the target, see left side?
I have ordered an IC .660 and will be shooting Nitro 4x5x7 heavyshot.
What do you think?
