I do have one. I have used it to decap a bunch of brass and to swage the primer pockets on a bunch of 556 brass. It seems to work very well so far. I have also purchased the priming system and bulge buster outs. I have not used them yet. The brass that I have deprived was 38 split, 357 mag, 44 mag, 223/556, 9mm. I have also sized some 327 Federal Mag brass.
