Widely used for wet tumbling used brass cartridges, these little tumblers have lasted me for thousands of rounds and almost a decade of reloading. It never dawned on me to add a cap to rinse out the dirty water. V1 only has a small slit and doesnt spill any steel pins, v2 is a bit faster but lets an occasional pin come through. Enjoy !
