ROADDOG... I assume you are right... I'm getting as much out of the case as practical, by scraping them out with a dental pick & small screw driver... however some of the cases ( for what ever reason ) have quite a bit of residue in them, either carbon from a previous load, or black powder stuck to sizing lube film ??? I'm pretty anal when it comes to loading, & the stainless pin wet tumbling has really spoiled me... I'm used to looking inside cases that all look like new
