    Having done similar projects myself, the easiest way is to make a punch. A valve out of an big engine works nicely. Use a grinder to reduce the stem area to a punch about 3/4" long by 3/32" O.D. . A big nut the case can set on that has a hole large enough for the spent primer. Place nut, case and punch about a foot from a car on the concrete garage floor. Slip a 2"x4" 8' stud on edge under the car some and over top the punch. Press down on the free end of the stud.

    My dad used this technique to de-prime live cases. Note a 50 cal primer is at least a 38 S&W in power. Second note The valve could have come from Pratt and Whitney R-985. Choose intake valves if you can, sodium filled exhaust valves could get exciting.

    Added The handle on my screen door is a 50 cal. blank with 2 5.56 to space it from the door. I keep a pencil in the blank and a pad of post it notes (perforated via 22 LR) on a finish nail right beside it on the trim.

    Hydraulic method will not work well on crimp blanks.

    Might try Hydraulics. With the case resting on a flat area with a hole drilled for the primer to fall thru, fill the shell casing with lite oil or water. Then with a tite fitting wood dowel inserted about half down into the shell's neck, hit the dowel hard and fast with a hammer.
    Compresses the water to high pressure and forces out the primer.

    Here's a fancy set up..

    I made the mistake about 20 + years ago, I bought two surplus 50 cal rounds for the boys to have. I pulled the bullets dumped the powder . 1st case I used a punch thru the neck of the case . I had the case on a flat table what the heck its just a primer big mistake , well after the ringing in my ears stopped and my fingers were all accounted for and not too burned up . I realized I had screwed up. [:I] not to mention scared the crap out of me
    second one was more planned and no harm was inflected
    some sound advice wish I had ask some one back then

    If you think the primers are live, just spray a little 3 in 1 oil in there and let it sit an hour or so. That should kill it.

    Then just take a small diameter steel rod and hammer, resting it on a surface where the primer can fall through, smack it a time or two to drive the primer out.
