Vid confirms it was the hot round, combined with SOL factors.
Synopsis if u dont watch the full vid.
Scott fired the remaining 12 SLAP rds he had. Non blew the gun up. But about 7 of them caused the cap to take lots of effort to unscrew. Hes a big dude and he had much difficulty unscrewing. Then to remove the brass took 10 mins and a vice grip. So had the rd he shot b4 his accident acted in the same way, would Scott have paused for a moment and not shot the defective rd.
Then he shot 1 rd purposelly overloaded to blow the gun. Which it did. Almost everything blew up in the same way, except the ears didnt get sheared off. But the cap blew off and left similar thread sheering marks. The butt stock blew off, and the lower separated from the upper. The base of the brass came off and the rest was stuck inside the barrel.
So all in all, freak accident of combined forces. Makes u wonder how a bolt action 50 would have reacted. I mean any 50 that blows up with that much pressure wouldn't be safe. So i don't think its the guns lack of safety measures thats at fault. But I get what people are saying about the gun being unsafe, because the way it's designed, the only option for over pressure is to have the end cap come straight back into the shooter. Compared to other rifles where there are vents or parts don't come straight back into you. But then again, with such a large caliber and powder, would it really matter? I would like to see him do the same test with a Barrett M88 and then some kind of bolt action 50cal. CRS Firearms had a review of the incident that makes sense, but this is above my pay grade, so take my opinion with a grain of salt.
