I've got a Ruger American gen2 in .223 that shoots every load under 1.5'' and it's favorite load of 73ELDM/H322 consistently shoots 1 hole groups, the best 4 shots measured .18".
The last few years, I've been fascinated with borescoping rifles mainly to see how effective different cleaning products actually are and the relationship of fouling on accuracy. This particular Ruger barrel has chunks missing from the lands and in two sections the chunks are impregnated into the grooves. It looks like tooling gouged the land and smeared the still attached chip into the groove. I've always been under the impression that Ruger barrels were hammer forged, so how is this even possible? If one of those chips came loose and out the barrel @3000fps I'm pretty sure it would ruin the barrel and whatever muzzle device was on it at the time, so I sent the rifle back to Ruger. Anyone on here with knowledge on how barrels are made have any theories?
I ruined my borescope lens so the pics aren't the clearest, but hopefully these will give you an idea of what I'm trying to describe.
