Totally off-topic - not knife related!
I worked part-time as an RO at a local public range. The 629MG led an uneventful life, shooting homebrew .44 Russians, Specials, and wimpy Magnums. I had shot >200 Russians and Specials one day when I ran out of them and went to my last box of ammo in my range bag - my one Magnum load - a 300gr LSWC over 6.2gr Titegroup, a wimpy load (875 fps) but a very fast burning powder and a long/heavy bullet. To cut to the chase, the lead and propellant residue in the chambers made inserting those long cartridges difficult - but made the fifth round's uncrimping and exiting slowed, causing a pressure spike. That's all it took.
In shooting, I was free-hand shooting at a 16" steel plate at 110yd, as I had done all day. The first three shots found the range, the fourth dinked it, and the fifth went 'Boomfff... tinkle - tinkle' and produced no recoil. One range-lane neighbor said 'Miss!' while another got my attention, 'John... your gun...'. Tears welled up inside when I looked down at my expensive revolver - in pieces. I took stock - two bloody dots on my left forearm and a chipped left safety glass lens - I was blessed.
I tried - a double charge was impossible to load with my press due to the long bullet that had to be seated. The most I could get in was ~10.5 gr - and the propellant maker, Hodgdon's, said that was safe - under normal circumstances. They also agreed that chamber build-up could have slowed the bullet's exit from the case - and 'just' 6.2 gr could burst the cylinder, due to the propellant's fast burn rate.
I called S&W - their first question was concerning my use of 'reloads'. I told them that if they proof-tested it with commercial ammo, that was the last time it saw it. I made all of the ammo that revolver ever shot, after it left the factory. They sent a pick-up - tested the remnants - and returned the barrel as still being seviceable. They arrived at the same answer - probable 'stuck' bullet. They did the unimagineable - offered to sell me a new one - actually a 4" 629 regular production - the next one to come down the assembly line - and for a song. Delivered, it was less than half the least expensive sale price I could find on an existing old stock 629MG. Oddly, the standard production 4" 629s usually sell for more, too. I was fortunate, even if others offered other, less kind reasons for them to behave in that manner. To me, they are first rate - top drawer.
I was blessed, lucky, fortunate, whatever you want to call it. Of course, it all happened because I did something stupid - very stupid. Always clean a revolver before going from short case rounds to longer Magnum rounds - I knew that... but it was late... and I was stupid - careless.
