Thread: DIY Gunsmithing mistakes

Well I will kick it off

Recently I had the bit between my teeth and wanted to form a 38-303 case from some old CAC 303 sporting ammo
Well I didn't know that the powder in that old junk goes sticky
So I pull the bullet in my kinetic pull and get the powder out
Tap the neck to make sure its properly empty
Set it up on a bench to quickly anneal the neck with a gas blow torch so that I can form it up a few calibers

Huge Bang and the case flies a couple of meters in the air
Big burn mark on the bench top and a primer sized crater about 5mm into the wood !

So now I know that sticky powder in CAC cases is still pretty keen and able to kill something
