Hydraulic depriming for Berdan primed brass
I built some of these eight or nine years back for the 7x57 and 8x57 rounds. They were your basic bullet-sized punch with an anvil with a hole in it to allow one to fill the case with water to the base of the neck, insert punch and dab it smartly with a plastic mallet, thus shoving the water out the primer holes, and taking the primer with it.
This is a fine activity for the summertime, and for teaching the kiddies how to use a hammer without mashing their fingers, but it is a tad bit messy for indoor use. I'm putting some together for use with my sizing dies, and cooking oil, for use at the bench. I may make up a set for the 7.62x39 also. I have a lot of nice brass cases for that round, and it seems a shame to let them go to waste.
Any nominations for other calibers?
