This is just a hypothetical, as I am not totally dry on primers, but . . . I believe the physical steps are not too complex (remove anvil, flatten primer). The chemistry is pretty simple too - KClO3 + antimony sulfide+ aluminum powder + ground glass. All of those chemicals are legal to purchase. Obviously, it needs to be mixed in very small amounts. But with an eye-dropper, it seems pretty straight-forward, if seemingly labor-intensive. I must admit some trepidation, however. I highly value my eyes and fingers. Has anyone here tried it?
