wyliearms Posted February 11, 2016 Share Posted February 11, 2016 (edited) So I bought a Hornady Hot Tub for Christmas to get into ultrasonic cleaning. I've cleaded guns, parts, etc in it and it works great. I recently decided to use it to try a load of 45 ACP brass. It cleaned it great. Looks really good. Here is the issue. Tonight I started loading some of it to get ready for Saturday. Out of 200 rounds, about 7 knocked the top of the primer and left the circular sleeve in the primer pocket which as you will know, caused prining issues. Has anyone else ran into this? I was using their case polishing formula. Edited February 11, 2016 by wyliearms Link to comment Share on other sites More sharing options...
Arlin Posted February 11, 2016 Share Posted February 11, 2016 I have had this issue with military brass but none so far with other brands. I do not use ultrasonic cleaner but do use vibrator with corn cob media and Dillon case prep. Arlin Link to comment Share on other sites More sharing options...
oteroman Posted February 11, 2016 Share Posted February 11, 2016 Sounds like the cases are not totally dry.I use SS pins and this happens when the Cases are not totally dry... Link to comment Share on other sites More sharing options...
wyliearms Posted February 11, 2016 Author Share Posted February 11, 2016 I've never had this issue before until I started ultrasonic cleaning. All was mixed headstamp... Link to comment Share on other sites More sharing options...

oteroman Posted February 11, 2016 Share Posted February 11, 2016 OK ?? It is a drying issue period. Link to comment Share on other sites More sharing options...
wyliearms Posted February 11, 2016 Author Share Posted February 11, 2016 How long should they dry then? I would think setting out in the open for that long at room temperature would have been plenty of time. I also blew them out with an air gun once they came out of the solution.

dillon Posted February 11, 2016 Share Posted February 11, 2016 If you plan to wet-tumble cases, deprime them first. What happens is the brass corrodes, weakening the primer cup at the corner. During depriming, the primer cup separates, pushing off the end of the primer cup and the anvil, but leaving the sides in place. Not a happiness making thing, and one of the reasons Dillon Precision only offers dry-media case cleaning equipment. Link to comment Share on other sites More sharing options...
Steve RA Posted February 11, 2016 Share Posted February 11, 2016 Also it's possible - if it wasn't your fired brass - that it may have gotten wet before you got it. Everyone runs into this eventually if they use "pick up" brass. Save the case and sell it for scrap along with used primers. Link to comment Share on other sites More sharing options...

Haven't gotten into wet tumbling yet myself but occasionally pick up range brass that has been sitting in the elements for who knows how long. and leaves the side of the primer still in the case. I just throw them in my scrap bucket and move on. If you want to clean them with your Ultrasonic cleaner either resize and deprime first or pick up an universal decapper so you dont scratch up your resizing die with dirty brass.

safeactionjackson Posted February 11, 2016 Share Posted February 11, 2016 As said, deprime first. Wet tumbling with stainless steal pins will be a much better option then ultrasonic cleaning. Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
wyliearms Posted February 11, 2016 Author Share Posted February 11, 2016 I'll go back to dry tumbling like I have been for 15 years. Tried and true....I knew it had to be something related to the ultrasonic cleaner because I've never had this happen before. Link to comment Share on other sites More sharing options...
safeactionjackson Posted February 12, 2016 Share Posted February 12, 2016 I think it's more on how you used the ultra sonic cleaner, you wouldn't of had an issue if you had decapped first, plus I doubt the primer pocket was actually cleaned after using the ultra with the spent primers still in place.

wyliearms Posted February 12, 2016 Author Share Posted February 12, 2016 I dont want the extra step of decapping first. It takes more time. I've also never really been overly concerned in clean primer poskets for pistol. I was hoping the sonic cleaner would save some time not introduce an issue.

However decapping on my 650 doesn't take long - not at 50 cases a minute. Link to comment Share on other sites More sharing options...
