Brushy Posted May 19, 2017 Report Share Posted May 19, 2017 Can anyone advise on this interesting issue I came across today? I've just neck sized and very slightly shoulder bumped roughly 120 once fired lapua 308 brass using a Forster bushing neck sizing die. After 50 or so cases I noticed a slight scratch / scrape mark on the necks. I opened the die expecting to see a brass shaving but nothing obvious. However upon inspection of the bushing I came across fairly significant brass buildup which i suspect is the cause. So the question is: How can I and should I clean the bushing to remove the brass transferred during the sizing process? Advice please! Link to comment Share on other sites More sharing options...
MrCetrizine Posted May 19, 2017 Report Share Posted May 19, 2017 Bronze brush should do it. Link to comment Share on other sites More sharing options...
The Gun Pimp Posted May 19, 2017 Report Share Posted May 19, 2017 Yep - common enough - bronze bore brush in an electric drill will remove it. When you roll the cases on a lube pad prior to re-sizing, the neck doesn't get any lube. To stop it happening again, just rub a little lube over the neck.

Grum87 Posted May 19, 2017 Report Share Posted May 19, 2017 Or use spray lube Be a miserable git and make your own - get on amazon and buy some lanolin, and some isopropnal, mix a little lanolin with a lot of iso in a spray bottle, shake, dump brass into an empty powder tub, couple of sqooshes of lube, lid on, shake....job done.
