The normal maximum chamber pressure for the .50 BMG is 55,000 psi. Proof pressure is 65,000 psi. For a production model to give way at 85,000 psi is entirely acceptable.Interesting the comment that the gunsmith told him the thread would strip at the breach at just 85k psi. I thought safety margins would be a bit higher than that.
Yanks don't proof their guns.The normal maximum chamber pressure for the .50 BMG is 55,000 psi. Proof pressure is 65,000 psi. For a production model to give way at 85,000 psi is entirely acceptable.
As a comparison, the .308 Win maximum chamber pressure is 50,000 psi.
Same thing struck me, I would rather say 2-3x safety factor. You need to take fatigue, wear and tolerances into account.Interesting the comment that the gunsmith told him the thread would strip at the breach at just 85k psi. I thought safety margins would be a bit higher than that.
Do you really believe that all US weapons manufacturers do not pressure test their products before they sell them to possibly the most litigious public in the world?Yanks don't proof their guns.
Hehe, you watched it.Yanks don't proof their guns.
Serbu can say what they like about what it could have coped with, but they cannot possibly know about any individual thing, unless it has been proofed. Even then, no guarantees as to how it might deteriorate later with poor materials, manufacturing, user neglect, etc. etc. Still looked like a pipe bomb with a barrel screwed on the end to me.
No comparison in bolt thrust between a 308 and a .50 BMG. Massive difference.
"Entirely acceptable" ? Good grief.
Fundamentally the chump carried on shooting his ancient unprovenanced dodgy rounds despite all warning signs, until eventually it blew. But they cost him "over $100 a round and were rare things" thus therefore very special.
To what end ? To shoot through an old fire hydrant and add content to his channel.
