I read a thread some where about some 10mm brass was not good to reload . There was a head stamp list of good , and not so good brass . I haven't been able to find that thread . Does anyone know about this thread ?
TIA
Brass that can be questionable are PPU and Armscor AUSA. They have been successfully reused but some have been a "NO_GO"!
I was sent some PPU stuff that was reloaded by a company, where the bullets had setback into the casings. Testing showed they would not hold their resized dimensions. After I did a crude annealing and resized them they did hold better sizing. Therefore the brass seemed to be stiff/brittle/work hardened...
Others experienced a casing blowout, which could have resulted in higher pressure form the bullet being set back. This overpressure blowout also caused the frame of his pistol to crack.
Be sure you test the case to bullet tension for bullet movement, if they seat so easily that the seem to just slide in, they are probably too loose. :o
Shadow nailed it. Starline brass is so cheap, I would suggest you just backorder 1K and call it good.
Starline has in stock now, $162 pr K, free shipping.
good stuff!
Shadow , Thank you very much for your help . I have some brass from ammo I bought , Remington (UMC) ,PMC , Hornady , and Winchester . I didn't know if any of them would be on the bad list .

Iv had good luck outta armscor...so far id say several of them have atleast 5 or more of my plinker loads(9-9.2 of longshot at 1.250) on them plus original firing. Still going strong and wet tumbled at that.
I would put PPU in the take it to the metal recycling company category.
