I used to collect accounts of firearms blowups with old ammunition. Understand, because of the Agnotology https://en.wikipedia.org/wiki/Agnotology on this topic, the posters often don’t know why...

If your powder looks like this, get rid of it immediately

I am of the opinion that the shooting community is more than just ignorant of the thermochemistry and dangers of old gunpowder, it is in fact, actively in denial. I accidentally learned about this...

Have you tested different lots of the same primer brands? Primers are a mix of components. there are allowable percentages in the mix, and the purity varies, along with the homogeneity. A Gun Club...

I would recommend that you dump the gunpowder for that particular batch of ammunition. I have written extensively on the thermo chemistry, life time, and dangers of old gunpowder. Gunpowder ages, it...

No. I have looked this question up in the Metals Handbook from the American Society for Metals, and I asked a Metallurgist. At the very start of the production line, forge workers were over heating...

I have a plastic detergent bucket full of WW2 unfired brass. I deprimed all of it as I did not want to fool with corrosive primers.

Good decision.
Hatcher is our primary source for the investigations conducted on the low number receivers. It is too bad that the reports he quotes must have all been destroyed. Anyway, Hatcher...

Gunpowder is a high energy compound breaking down to a low energy compound from the day it leaves the factory. Gunpowder lifetime is very unpredictable, but rules of thumb for powder lifetime is 20...

I know Hercules has a canister of powder, that they have had under water, since 1900 or earlier. I have reviewed the Army Ordnance Magazine from the late 20’s to the 40’s and found articles on...

This is an excellent discourse why single heat treat 03’s are so risky to fire. There are those irrational types who believe that low number Springfields only burst because of “bore obstructions” or...

Your picture is just awful and I can't tell if the receiver is stamped Remington M1903 or not.
I have examined Remington M1903 rifles and it is apparent to me that Remington was making profile...

Gunpowder has a shelf life. This is a high energy compound that is breaking down, from day one, to a low energy compound. Our gunpowders are either nitrocellulose or nitrocellulose & nitroglycerine....

You acted decently and hopefully I have edited out the insulting comments. Sorry.
Forum: CB Loads / Military Rifles
Oh yes, these rifles have seen a lot of service. Very few are in original factory condition, the vast majority have gone through several lifetimes of use, and several rebuilds. No one should expect...
Forum: CB Loads / Military Rifles
I disagree. A blown barrel and receiver does not necessarily mean a bore obstruction. Are you aware of modern day Swedish bore obstruction tests where modern rifles were tested with bore...

You totally miss the point, these are blown single heat treat receivers, blown in Army service, that do not appear within Hatcher's Notebook, conclusively proving that any calculations of risk based...

The most probable cause was over heating of the billets in the forge room. But given the poor process controls to be found at Springfield Armory, the receivers could have been ruined downstream.

The Army always used the FA34 primer in its ammunition. I am unaware of a similar, “less sensitive” primer until CCI made its military primers available on the market in the late 1990’s.

My two Russian rebuilds have the springs.
If I could have known how high the prices would rise on Russian SKS's, I would have bought enough to find some without springs!
