I was talking abou this with my old now retired gunmaker, old scholl master from suhl and very pernickety.
he had a good opinion about this saying it was not seeing as a problem for decades. if there was not the problem today with some proof houses- not all- he would not boggle to do it.
and it depends on the rifle or not? a stalking rifle making 20 shots a year with common loads will not explode so quickly
