In the early '70s when plastic 50 cartridge boxes for reloads were introduced, the MTM company advertised that they had tested that type plastic hinge to 2 million opening/closing cycles. I don't know if that was true but it gave us the confidence to switch over from wood.
Nice Review, I have the Lyman wet drum with pins which has separator baskets one with a fine screen for the pins. I am now buying a dry tumbler just for removing case lube and this is recommended for both tumblers. I just wasn't sure of the quality. Thanks for showing the operation and the flats on the shaft for holding it still. I didn't know about that. Cheers from the USA
