    I saw a KB'd Yugo Mauser, guess the Yugoslavians don't have good metal.

    I can understand the other more modern weapons going south but a 98 series action in good condition has a failure strength of at least 90K PSI with some going up to 120K PSI.

    Your case might fail but to get a KB means you really screwed up. You might get case failures at 55-60K on 8x57 brass though.

    Remember on a quality Receiver (Bruno, and nothing but Bruno, and none of the "contract") more than a few people have built 300 Win MAG rifles on it. There are reports of deformation of the bolt and receiver lugs on a 108K PSI load, no bursting. The key is that a Mauser will deform before it will fail because the Brunos are good metallurgy combined with spot hardening, the majority of the receiver are malleable. There is significant deformation potential in the receiver and you will get an out-of round chamber and a stuck/deformed bolt before you get an explosive receiver.

    In other words, that guy was "doing it wrong" or "going full retard". Never go full retard.

    Over all though people don't pay attention when handling a firearm and shooting it. If I get a shot that feels even a little off, I do a quick field strip and ensure everything is in good working order with no obstructions. It takes a moment and can save a gun and more importantly a life. There really are some things idiots and non-detailed or orderly people should do: Flying a Plane, Shoot Guns, Drive Cars, Operate Heavy machinery, reload ammunition. A ton of people handle firearms like dumb-asses. Ever see a pilot fly a plane without first going through a full checkout on it? Front to back, top to bottom, every control surface, etc? No, or you would see a pilot in a wreck.. which does happen. Like the plane our guns can malfunction and kind of like a plane, when they do it can result in large kinetic impacts, flying metal and wood, along with exposure to fiery hot gases. Metal almost never fails outright, there will always be signs if you look for them. Hairline marks in the finish on the weapon indicating micro stress fractures or elastic deformation. Bullet obstructions are the easiest to solve with a little attention. I don't clean my brass because I want pretty brass, I clean it so I can examine the brass for signs of impending failure.

    ...but their exists also in the human heart a depraved taste for equality, which impels the weak to attempt to lower the powerful to their own level, and reduces men to prefer equality in slavery to inequality with freedom.

      Just look into each case before you place a bullet and you're GTG.


      Good advice. I practice that every time I load.

        This ended the reloading days of a good freind who was in early 80's , No one was hurt thankfully. Thompson contender chambered in 7-30 waters . I pulled the trigger on this .
        I was done shooting when he showed up and he asked if i would fire form some brass for him , reluctantly i agreed . I was shooting very well and had hit the 200 meter dinger every shot but one with the iron sights then got to a double charge . When the remaining loads were pulled two more doubles were found. The rear sight was never found and the sight base was lodged in the overhead
        I no longer shoot anyones reloads except my own.

          Just out of curiosity, what load/powder was he using that allowed him to double charge the case without overflowing?

            You would think that that guy would have figured that after the 3rd gun blew up on him that he would just STOP already...

            How many guns do you have to ruin before you get the idea? It looks like he blew up his whole collection! And I dunno about how he did that with the .22s!
            7 Billion people on the planet. They aint ALL gonna astronauts. Some will get hit by trains...

            Need GOOD SS pins to clean your brass? Try the new and improved model...



            And remember- 99.9% of the lawyers ruin it for the other .1%...

              As i recall the load was 12 grains of unique . It was/is common for people to use fast pistol powders and/or seating the bullets into lands for fire forming wildcats. He was using range pickup 30-30 brass since he was to frugal "cheap" to buy 7-30 waters brass

                Ok that makes sense. I know that 10-12 gr of Unique is a pretty popular load for cast boolits in 30-06, 8x57, and other similar cartridges. Very easy to double charge, though!

                  It can also happen with factory ammo. Last year I had my Glock 30 .45ACP blow up in my hands. Factory ammo right out of the box. I sent the pistol and remaining ammo, including the ruptured case back to the ammo manufacturer. They would not admit liability, but they sent me a check for the full price of a new pistol. That should tell you something.

                  I've been reloading for around 35 years, fired many thousands of rifle and pistol reloads, and never had any problems. I once chronographed some of my 22-250 reloads alongside fome factory rounds. My reloads were much more consistant, velocity wise, than the factory rounds. More accurate too.

                  Of course I'm careful and cross-check receipe's between at least 3 books before I load anything, and I never try for maximum velocity. Best accuracy is usually found well below maximum loads anyway.
