These things goof up any discussion. We start with a KB and end up discussing if we can get radiation poisoning from our microwave.
Which is why the THR staff tries keeping the threads roughly on-topic. And why there’s a “report” button

I'm sure every reloader thinks a KB will never happen to them.
OK, I just don't see the upside of reloading considering the danger, however slight, and the fact I'm getting MOA from factory ammo. YMMV
Hmmm.... If the 116's that have been seen blown up are all WSM's, I wonder if people are loading 7mm Rem/Weatherby Mag or .300 Win/Weatherby Mag data for the WSM's and those larger cases utilize larger amounts of powder inside? I've read the WSM's get the same velocities with smaller powder charges because they're more efficient, and velocity claimed for the WSM line is pretty high. It may lead to an inexperienced or distracted person to miss the correct load data and read the wrong one if they're chasing velocity numbers. I don't know if that is enough to cause one of those, but it may be something...
Those pictures are of A-1 catastrophic failures, not just a run of the mill blown primer or even a stuck bolt!
I hope the guy has some sort of normal life after this. And glad you didn't take the bolt in the eye, across the beak or somewhere else that would leave permanent damage!
Stay safe!
MOA all day? If you do your part?
I believe you are wrong, but I won’t be so arrogant as to speaker for all of them, just myself.
I’m confident a KB won’t happen if I pay attention to what I’m doing and follow proper guidelines and procedures.
I pretty sure bad things can happen if I don’t
Makes sense...The powder charges wouldn't fit. Most rifle loads are in the range of 85-100+% case capacity, with the majority on the right side of that curve.
Run the large hole insert on your powder thrower, and always dump the first charge back in the hopper.FWIW, most recent Shooting Times that I received yesterday (Feb 2019 issue on pages 22-23-Propellant Loading Pitfalls, A. Jones mentioned this as a cause for a kaboom. The person firing reloads only had one powder out at a time, his loads were documented as normal, etc. and the case gave way in a No. 1 Ruger firing a .308. Neither powder bridging, bullet condition, etc. was a cause.
What turned up was that the shooter had reloaded .45 ACP with Unique prior to reloading his ill fated .308 round. Jones believes that the cause was that the powder measure was not totally emptied of the Unique powder before reloading the .308 with IMR 4064 and thus the shooter inadvertently made a binary combination of powder in a cartridge. With that instance, the rifle powder would be on top of a faster burning pistol powder from the very bottom of the measure in the cartridge, this could cause the pressure level to skyrocket to the estimated 90000 to 100000 psi level necessary to damage the firearm.
Takeaway from this is to thoroughly empty your powder measure before reloading another cartridge. All it takes is one bad cartridge to ruin a day of shooting.

Had a guy do that here.
He left some Varget in his powder measure when he opened a can of H50BMG for his AR50.
Best the other guy at the range could tell, he fired one round loaded with Varget with notable kick, flash, and recoil. Stiff bolt, too. Undaunted, he touched off another. The next round was less of an earthquake, but still excessive. Still some Varget before the measure got down to the H50BMG. The third was normal. The rifle was not damaged, which was very impressive when he admitted what he had been doing.
That Walker trigger business has been talked to death. How about we stay on topic of the destroyed Savage. I think we have gone as far as we can on this happening.
Yikes.
Makes me wonder if this is a common explanation for a lot of mysterious one off kabooms where the bullets are pulled and the charges found to be normal. Course, the primary evidence would be destroyed in such a case.
I've always cycled my powder measures after returning a powder back to the original container but I am thinking total disassembly or using different powder measures for rifle and handguns might be in order.
