A little side track to the topic here, but I got interested in pressure events long ago with cast bullets and light charges and case fillers etc so this tragic event re awakened my interest. My google fu is pretty poor, my library limited, but I tried again to research air space and slow powders...it's shocking that anything that dangerous can be that hard to find data on. Anecdotally, I had a friend, now deceased who was involved in a tort case in which he, as an expert witness, duplicated a light load of slow powder in a .264 Win I think...with some input by Rick Jamison, blew a model 70 all to hell and documented and filmed the whole thing. After all that, a settlement was reached, all the plaintiff got was medical expenses and an undisclosed sum, the ammo company (I can't recall) admitting no liability. Anyway, first try, John blew up the model 70 with a light charge.
