Crinkled Cases

[venomballistics]

I have on occasion like 3 or 4 times. But and a big but! Don't do it to rounds that are loaded near maximum pressure. Because you just super crimped your bullet and it's now under sized due to the resizing.

I've done this to pull down a batch of revolver ammo.
The "super crimped" condition is not what happens in this process.
Brass springs back from any mechanical work applied.
If it didn't, a functioning auto design would have been impossible as it's a trait required for ejection.
Lead of the bullet, on the other hand, does not have this trait.
When we cram it into the sizing die, everything conforms to it.
When removed from the die, the bullet remains undersized and the brass springs back, releasing it.

No Sir, I made a Faux Pas I have always sized my brass. I just do not trim handgun brass.

Fair enough but not sizing for as cast bullets, esp. WC's, isn't as odd as some may think.

Have been told that a long time ago. Had been told if you are using them in the same gun then sizing wasn't really needed. Sort of like neck sizing rifle cases that are to be fired in the same rifle. Have never tried it, though.

Will have to wait until it happens again. When I get one the next step for me is to run it through my sizing die that I have taken the decapping pin out of it. Will post when I do and send you a PM if that is alright with you.
