Just curious what others do with this situation. Thought I might have noticed some changes during sizing of about 100 pieces of brass. Lube build up?
Unless you're using a FL die to neck size with, there's nowhere for crud to gather. I clean mine because they're left out on the bench and get dusty.
Dillon's lube (the bottle I have, anyway) is lanolin dissolved in isopropyl (?) alcohol. I have actually used lanolin from a tube, works well, but kind of 'thick' for a lube and I can see needing to clean the die once in a while.I use Dillon's lube and find that a couple squirts of brake cleaner up my resizing, seating, and crimping dies in the toolhead every 2-2.5K rds keeps them clean and free of crud.
May be using a bit much of Imperial? I've found that all it takes is for the case to feel slightly 'greasy,' but then again, I"m not a high volume reloader. I only run my finger tip across the Imperial every 3 or 4 cases, but I run my fingers over EVERY case, to make sure it has enough lube. Anyway, just some thoughts.I use a FL die to FL size w/ Imperial wax as lube. Every once in a while I notice dents in the shoulder. Time to clean die.
Remove from press (RCBS) and remove deprimer stem. Take about a 1" wide strip of old tshirt, work it thru die then pull back and forth to get
xcess lube out. May take a large piece of shirt on screwdriver and force it thru/swab out die, first, then above treatment, depends.
Have also used qtip w/ soap/hot water.
