Thread: Weird irregularities in necks of fired cases.

Today I decided to have a crack with the 7mm at some of my heavier steel targets (apparently my soft-point loads will still sail through 1/2" of steel without even moving the plate... so there goes some of my targets).

After picking up the rounds and looking at the neck I noticed this weird flattening in the neck. There's nothing in my chamber obviously... so I'm a bit confused as to what is causing this.

This brass is getting pretty old and tired so I should be throwing it out... but it's not showing any signs of giving up just yet, even about 7-8 reloads in.

What do you think guys? I thought it might be the extractor giving the neck a whack... but I can't see any impact marks.
