Aggrofish Posted July 5, 2020 Share Posted July 5, 2020 If this was rifle I’d say I was going to have case head seperation, but this is at the bullet end and I’m assuming is a mark from the bullet itself? Maybe I’m seeing this after a couple firings? The inside is smooth and a paper clip won’t catch on it. Throw em out or normal? Link to comment Share on other sites More sharing options...

superdude Posted July 6, 2020 Share Posted July 6, 2020 They look like they have been fired in a stepped chamber. Link to comment Share on other sites More sharing options...
stick Posted July 6, 2020 Share Posted July 6, 2020 Definitely not normal. Throw them out. Link to comment Share on other sites More sharing options...
AHI Posted July 6, 2020 Share Posted July 6, 2020 Have been seeing this for a while . This is from range pick up not one of my guns.Thought it might be from a miss adjusted LFCD but OP says no. So next would be a chamber issue . After sizing and loading I have seen no Issues . BUT When in doubt through it out! Link to comment Share on other sites More sharing options...
BJB Posted July 6, 2020 Share Posted July 6, 2020 Fired in a stepped chamber. Likely either a Walther or H&K. There's nothing wrong with that brass. Reload it normally. Link to comment Share on other sites More sharing options...
Aggrofish Posted July 6, 2020 Author Share Posted July 6, 2020 Thanks. Its possible it's not my brass. I try to pick up only my brass, but sometimes I will just grab 9mm cases without looking for the torched / burned titegroup marks lol. Mine is usually really easy to spot but it's been 100 degrees out so... Link to comment Share on other sites More sharing options...

superdude Posted July 6, 2020 Share Posted July 6, 2020 (edited) Search 'stepped chamber' on google and you'll see some examples. that's what the mark is from. Apparently the Walther Q5 Match has a stepped chamber. https://www.shootpointblank.com/product/wal-2846977-ppq-classic-q5-match-poly-9mm-15rd Edited July 6, 2020 by superdude Link to comment Share on other sites More sharing options...

Farmer Posted July 6, 2020 Share Posted July 6, 2020 Almost looks like a bullet stop ring for 115g bullets. I would load em & shoot em. Seat a bullet past that ring and see if it bulges. Link to comment Share on other sites More sharing options...
gng4life Posted July 6, 2020 Share Posted July 6, 2020 Does the line on the outside have a slight "hump" to it? Or is it a scar or score into the brass? I was betting on the bullet seating ring but not sure from the pics. Let us know. Link to comment Share on other sites More sharing options...

Looks like a line from a crimp but left after the fact. 6 hours ago, gng4life said: Does the line on the outside have a slight "hump" to it? Or is it a scar or score into the brass? I was betting on the bullet seating ring but not sure from the pics. Let us know. no hump. Could be from a previous crimp, but it’s not on all cases. All my rounds are tapered to .375 for the last 7 or 8k. Link to comment Share on other sites More sharing options...

If the ring is there after reloading then it's a die issue, but that's very strange and I personally don't know any 9mm dies which will leave an indented ring/collar. Crimps don't really leave rings. As I and others have written some chambers are stepped, however your sizing die should smooth them out in the reloading process. Did you say this was from range brass? Which would indicate you're picking up someone else's brass. Oh these odd problems, enough to make us pull our hair out. Of course some don't have much hair to tug on.

That's the problem I'm not sure if it's my brass or not. I usually go out once a week and shoot about 200 rounds of pistol. If I'm shooting in one of the outdoor bays there's a lot of other brass laying around. If I'm shooting in one of the covered ranges it has a concrete floor and everything I sweep up is my brass. After tumbling I find a few of these and I'm sure several have made their way into the case feeder. None of my loaded rounds have any issues. I was just curious and the line reminds me of the ring you get on rifle brass at the head before you start getting case head separation. If I catch em I throw them out. 28 minutes ago, HesedTech said: Link to comment Share on other sites More sharing options...
mstewart Posted July 6, 2020 Share Posted July 6, 2020 I have 2 Walther PPQ 9mm pistols and they both have stepped chambers. They produce brass that looks exactly like that. I have been reloading those for 4 years now with no issues. Most sizing dies will not remove,but it is not a problem. I use a Udie and it takes it out.

I reloaded many similar brass and like others, have found they smooth right out with the Dillon or Lee sizing dies. Honestly you will have more reloading issues with CBC brass than these ridges. I think the general consensus is, load away it’s a non-issue. Enjoy! Link to comment Share on other sites More sharing options...

I’ve probably loaded tons of them without even knowing. Link to comment Share on other sites More sharing options...
RePete Posted July 7, 2020 Share Posted July 7, 2020 It appears, to me, that the case had a wobble when it was entering the sizing die. I have had that when I used a Lee Progressive 1000. Link to comment Share on other sites More sharing options...

Aggrofish Posted July 12, 2020 Author Share Posted July 12, 2020 Update: as other have suggested the line goes away after sizing so as a number of you have pointed out I probably picked up some walther brass. Link to comment Share on other sites More sharing options...
