O hwell, topics like this make me wish I was 17 again. Would'a got me an engineering education and find out for myself. Can't help wondering, you know - when you see a fellow shooting modern 70mm shells through a pre-1914 gun with 65mm chambers, season after season, without any trouble except the barels are slightly off-face. Is this felow just lucky? Or when another fellow's brand new magnum semiauto goes burst for no apparent reason - is that fellow simply out of luck? Or should I believe a friend of my Dad's, who's a high-pressure pipelines expert - he says 8 out os 10 bursts are caused by hidden defects in the metal, which are enhanced by accumulated stress, and while the burst will probably coincide with a rise of pressure over everyday level (e.g. a slug or goose load), this pressure rise is simply a trigger, not a cause, of the burst.
