I formed my 6slr cases with a borrowed fl bushing die (thanks Mick)

I lightly lubed the first few cases by getting a little on my finger tips and rubbing the neck shoulder area. And as the lube wore of my fingers the cases still went thru the die so I just stopped lubing and kept sizing. All 300.

And then noticed they looked like this


The shoulder has been concertina’d in a bit.

And it fired out ok.

But I resized the original 18 cases I fired to use fireformed cases for a ladder test. And a few have come out like this on second firing



The faint line does not go the whole way round and is raised. You can feel it.

So my first reaction is that the cases have stretched when firing out the wrinkle and I’ve over worked them and this is a separation on the way.

But the ring does not go the whole way round, is not on all the cases and the bent paper clip is not hanging up on anything inside the case. What else
Could it be!

Could be just a barrel mark

Noticed the paperclip tool. If you didn’t pick anything up and only some of the case have the mark then it probably isn’t an issue.

If there was a scratch in the chamber shouldn’t all fired cases look like this?

Remove the barrel and inspect the chamber ( the end with the big hole). If there’s something there causing that mark you will see it.

Trevor,

If you need it fixed, bring it over. I can pull the barrel and have a look. Who did the chamber, and what reamer did they use?
