Kurt's recovered bullets

[Gunlaker]

Wow. The paper on the shank near the base reminds me of crumpled cases I've seen that have been fired when breech seating with smokeless. The pressure builds up before the case seals the chamber and gets between the case and chamber and crumples it. Maybe something similar happens with the sides of the bullet in the cupped area. Mind you that probably doesn't explain that you've only seen it with wet bores.

Chris.
