So, after shooting on Saturday, it looked like my target had been peppered with staples from a shotgun shell, rather than a handgun. Found lots of little copper pieces in the target area. Pretty sure its shedding the jacket, wondered if anyone has run into this? I'm told that match grade barrels have sharper rifling that can make this happen. I was shooting an XDM .40 with Blazer Brass ammo. Couldn't tell if it was just the ammo, but it seems like the WWB did not have this problem.
