As interesting a story as that is...
I'm left wondering just how in the bloody hell anyone that calls themselves a handloader makes 2,400 reject rounds of anything.
Is he an idiot? How good can the good ammo be if he's made 2,400 bad ones? And one of them had a piece of decapping pin inside the loaded round?
Gotta hope that when he grenades a rifle, it's only him that gets hurt.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
