Glad to help, that's where these forums work very well, sharing simple knowledge Just make sure you rinse the ultrasonic cleaner with clean water when you have finished before you put it away because Cillit Bang is corrosive, probably an idea to rinse the cases too before you put them out to dry for the same reason. With rifle cases I put them through the ultrasonic cleaner after I have resized them mainly to remove the resizing lubricant and do an initial chemical clean before going into the tumbler for a final polish Edited April 11, 2018 by Vince Green Quote Link to comment Share on other sites More sharing options...

I normally do remove the primer but talking to the chap who owns my local gun shop he does a lot of reloading he recommended to leave the primers in , Said he didn’t want to put dirty cases in his press, Quote Link to comment Share on other sites More sharing options...

Leaving the primer in would mean that the primer pocket would be dirty. Quote Link to comment Share on other sites More sharing options...

Yes point taken, from what he said he initially cleans the brass Before sizing, does all his case prep then cleans his cases again before he puts them together Quote Link to comment Share on other sites More sharing options...
Savhmr Posted April 13, 2018 Report Share Posted April 13, 2018 (edited) Leaving primers in also means when tumbling that a lot of lead syphate (oxides) are transferred to the tumble media...NOT good for health. A gunsmith advised me always to wear a face mask when removing cases from tumblers as the fine dust can be very high in toxins that if inhaled, are cumulative in nature due to the lead. I've already covered the open louvred top of my tumbler to prevent the dust when tumbling for this reason and now always de-prime before tumbling. I use an U/S cleaner after sizing and trimming/deburring to remove lube and brass fragments. Be careful just what chemical mixes you use in an U/S cleaner as some will affect the brass, and could weaken it depending on concentration and duration. It's advisable to rinse brass in fresh water after using these cleaning chemicals. I can't see how mixing strong alkalies such as washing up liquid, with strong acids, such as vinegar, allows them to work as well as one or other on their own, but I'm no chemist. Seaclean is all I've ever used and it does the job well enough. Edited April 13, 2018 by Savhmr Quote Link to comment Share on other sites More sharing options...

Interesting I think you may have a good point , that may be another good reason for using an ultrasonic cleaner as all the dust would stay in the water Quote Link to comment Share on other sites More sharing options...

Savhmr Posted April 13, 2018 Report Share Posted April 13, 2018 You can get fairly cheap corn cob media via Ebay (don't buy it at gunshops where you'll be ripped off!) and from some pet supplies places where it and walnut media are both used in some bedding materials. https://www.ebay.co.uk/itm/SAND-BLASTING-SHOT-BLASTING-TUMBLING-POLISHING-CORN-COB-GRIT-MEDIA-10-14-5kg/302618760927?hash=item46757bd6df:g:5OkAAOSwVFlT2PQQ Quote Link to comment Share on other sites More sharing options...
