That one's been around for a while. I've seen it a few times in the last year or so. Hard to believe that much damage can be caused by just the bore sight device inserted into the barrel.I'venever seen a rifle barrel bannanapeel like that. I've seen a few shot gun barrels that had some bulging and maybe a strand or two peel back an inch or sobut never a full bannana peel of what appears to be over a foot of barrel. I doubta quality barrel,that would hopefully be on a$1200rifle, would fail to that extent.
