I have cleaned four .308 casings in a Lyman TS-700 Ultrasonic Cleaner. Fully submerged, the casings have been cleaned for a total of 180 seconds and subsequently rinsed under running water. The three of four primer pockets are completely spotless, with one primer pocket holding onto a small portion of residue. I have run a Q-Tip down inside the casing to the bottom of the casing and forcing it along the inside wall in order to wipe out any excess residue. The Q-Tip comes out with very little, or no, residue on the cotton.
Sounds promising for sure. How clean is the inside of a case after simple submersion and rinse, no ultrasonic?
