I just went out to my gun room and examined my Krag. Not only is the bolt locked into the back of the receiver and stock there is a small protrusion at the back of the bolt that locks into the rear arch of the receiver, I do not doubt that the steel used was inferior to more modern designs but as a Tool and Die Maker I naturally question statements that are unquestionably accepted as gospel truth. Has anyone here ever had a Krag bolt fail or blow up in there face?
I was handed a Krag bolt at the gun range that had a crack through its lug. Post WW1, there were a lot of Krag's being used, now they are collector items. I found warnings in a 1960's American Rifleman about Krag "flame hardened" bolts. People expect everything to be on the web. There is about 300,000 years of human history that occurred before the internet, and not all of it was written down, and few of that is on the internet.
And when it comes to gun blowups or accidents, is there a legal requirement to report, and a publicly searchable data base? Lots of gun accidents don't get reported and I believe it is due to all the harassment you get after accidents from the people who believe in the "Just World" theory. That is, we live in a Just World. Good things happen to good people, good people are blessed. Sun shine and happiness is theirs, because of their virtue !!! But, bad things happen to bad people, The Just World corrects those who are evil. Therefore, if something bad happens to you, it is because you deserved it.
I recently ran into a Vietnam helicopter pilot who held this view. He stated there was always one guy in the squadron who would come back from a mission with his helicopter shot up. He truly believed that there was a pattern, he was not cherry picking events, or ignoring when others had bad luck. No, it was that certain helicopter pilots were more than unlucky, they were fated to be unluckily. There was just something about them that made their helicopter a target when all others came out unscathed. Irrational attitudes like this are common, and who wants to deal with the negative attitudes of people like this?
