Back when corrosive primers were a selling point. Be fun to shoot a box or two!

The head stamps indicate the box contains Winchester/Western, Saint Louis, Remington etc. cases. The primers indicate all cases have been fired because the primers have been replaced. And then there is the infinity mercury has for brass. In the old days it was believed the case became brittle because of the mercury when fired. That was before the Internet; now? I am sure some reloader can tell a convincing story about how wrong the old folks were.And for match accuracy they used mercuric/corrosive primers.
I have nothing to gain by firing brass that is suspect and then I find nothing entertaining about firing a case could be brittle. I did set up a test for checking cases that could benefit from being annealed; that was before ever reloader became an expert.

Friend's father passed and he offered a coffee can of assorted ammunition.
I accepted this and a box of modern .30 carbine, turned down the rest as I've spent my time decommissioning others ammo in the past.
One day this will be broken down, WD40'ied and into the garbage as I've got more brass than I'll ever wear out.
Thanks for your replies,

Craig, I sometimes wonder why some members do not wonder, I did; I wondered if mercury turns brass brittle when fired how did they reload in the 'good old days'?
It is as though we are the only ones that know anything, but be don't.

Fred, looks like you are slipping a little, In your above post you can’t spell your last name...

John, and I wandered; if I slipped, by how far?. And then I checked the keyboard. The u key comes before the I key.

And if I ever find out who Fred is I will tell him he is doing a good job' especially if his fingers are as old as my fingers.Comment

In the old days there was no such thing as 'sorta' 'kind-a', when it came to firing mercuric primers the case was brittle as soon as the trigger was pulled. SO? If the reloader was going to use mercuric primers and wanted good mileage out of his cases he would galvanize the inside of the case.
And if anyone wondered about what happened to the barrel when mercuric primers were used? The barrel started rusting as soon as the atmosphere contacted the inside of the barrel so it was not easy to clean the barrel fast enough. And I have some stuff that removes cupronickel, the streaker bullet; anyhow, read the instructions before poring down the barre.

And then there was a more civil exchange between Jack O'Conner and his readers. In one of his reloading books written in 1954 he cautioned reloaders about corrosive primers. Most had no clue because at the time if it was military it was corrosive. In the same book he mentioned he used lanolin when lubing cases. He was not trying to sell reloaders on lanolin, he did not strut around trying to convince anyone he invented it. He said his hands were in pain all the time, he claimed his hands were dried and cracked. It was about that time he said the only relief he got from the cracked skin and pain was when he used lanolin.
He said when he was sizing cases he added more lanolin for case lube. Today everyone believes they discovered it; with one exception.

German military primers were primary mercuric through WW2. While the Berdan primed brass is generally not reused, it isn't unheard-of. Moreover 8mm ammo from that era is still around and still shot (I do myself) and cleaning isn't an issue. Captured German weapons from that era show a range of bore conditions, as one would expect in a chaotic battlefield aftermath.Comment

Captured German weapons from that era show a range of bore conditions, as one would expect in a chaotic battlefield aftermath.'What I have learned from the 'old' 8mm57 ammo I have shot': I pulled the trigger, the firing pin struck the primer and smoke filled the air and then there was that whistling sound. I chambered a round, pulled the trigger and then nothing; I waited for over 15 seconds and then 'BANG!! And then I wondered? The firing pin busted the primer and then it tool over 15 seconds to burn through the caked powder. After then I wondered some more;Moreover 8mm ammo from that era is still around and still shot
I then started pulling bullets, the powder was caked behind the bullet on some rounds and ahead of the primer on others. I had over 600 rounds, I did not need the bullets or the cases, all I wanted to salvage was the powder. I formed 30/06 cases to 8mm57 cases, that worked. I have the 8/06 reamer, all I have to do is load neck size 30/06 to 8mm57 and then load.
And then there was all that 8mm57 ammo that split the case body as though the case body was hit with a shaped charge and streaker bullets. I know there is no such thing as 'I feel like I have been here before' in reloading but it seems I shot a bunch of WW1 ammo that streaked up my barrel; problem? That stuff was not easy to remove. That stuff kept streaking the barrel until it reduced the diameter of the barrel etc.
I still have close to 500 8MM57 rounds; I find nothing entertaining about shooting the stuff.
