not yet . Had just shot 5 rounds sighting in the new scope and was on the 2nd shot through the crony that it let go . Will look at the baffle to see if it's been eroded by gas cutting where it let go . The remaining piece on the barrel was tight so no way it had come loose , there's a mark in the exit hole but looks more like impact with the wood heap that bullet strike as there's no sign of copper . The back end nut was dragged up the isolation tube before letting go so that wasn't the problem . To me so far loss like shit happens material failure . With things getting lighter and thinner maybe we are cutting weight/material in the wrong places . I know I could lose more weight than my rifle .
