The sticky is at the top of this forum, it has 117 entries so it's quite a read.
My personal attitude on these is that in the hundred and some odd years since they were made and the thousands that were rebuilt during WWII, the ones that were going to fail have already done so.
I came to this conclusion long before the archived data (of the prewar military testing) was discovered.
As noted, of the million plus rifles built, less than 70 failed, of those failures many were due to circumstances that could happen to any rifle, I.E., an 8x57 round in a 30-06 rifle or sub standard quality ammo.
Having said that though, I would hesitate to turn the thing into a bullet hose and run it like I stole it.
It is, after all, a hundred plus years old, there was also a report I read, again from the military testing, that the right receiver wall was subject to cracking if subjected to a hard knock, the big question in this report was that it wasn't consistent as to location of impact.
Like tempered glass, you have to hit the "sweet spot" for anything to happen.
I have seen a couple that have been abused harshly over the years and are still chugging along so, at the end of the day, it's up to you, to run it or not.
