Resizing tools
Had both, Paco and DRock, at the time of the testing we did. Neither will go off if'n you tap em with a hammer.
We took a single Paco's die, which we bought special for a safety test, and we put it in a pipe. Put a round in the die, stuck the pipe on a 3/8" steel swinger made out of armor plate with the round at the bottom, stuck a steel rod in the top of the pipe and dropped an anvil on the rod. Did not go off. Did the same thing to DRock's. Same results although we could hammer the DRock die out since it was made out of steel rather than brass.
Smashed the Paco die so bad we had to saw off that end of the pipe to save the rest cause the die was wedged in there and the .22 round was wedged into the die. Threw the piece of pipe with the die in it into some old motor oil and let it sit there or a couple of months.
Paco's tools are patented and I don't believe that even the Fed's would let it go through if the tool allowed it to be turned into a hand held firearm with a 3 in" barrel. (That description is a joke by the by but it is patented).
We spent a bunch of time preparing for the tests like from Oct 2010 to Jan 2011, and we made safety THE key. We even tried putting rounds with the bullets pulled and powder dumped and put the dies on a flat piece of "bumpy" steel and "smacked" em around and none of them went off cause a "bump" might have been "under" the rim.
We smashed up close to $200 of die's destroying them on safety checks.
We sized over 12,000 rounds for the test and I resize and reform all my bulk ammo that I use in my .22's since then which is probably around 4,000-6,000 rounds. Ditto for shooting buddies on bulk ammo.
I don't care which tool anyone uses and I don't work for either guy so I don't have a dog in that fight either. Our goal when we started the testing was to see if sizing/reforming bulk .22 rounds resulted in a more accurate round. IE: what the fuss was all about. A project for a bunch of "mature" shooters. Some of us, mature shooters that is, get kinda bored with stuff and decide to mess around with it, like targets, shooting games etc. and this project.
Also tried sawing off the noses and filing them down and drilling a hole in the nose. Made a special collet that allowed us to hold the driving bands tight and chunked the collet into a mini metal lathe to kinda automate the process. Lot more messy than either the Paco or the DRock. Never did try the Waltz one's though.
They are both quality tools and which one you use if you decide to use one is a personal preference. I don't care either way. DRock does not market his product(s) relative to enhancing accuracy but if your weapons like nice and round .2245 diameter driving bands you do get better accuracy whether or not he "talks" about em or not.
I communicated with both "Paco" who is an example of what cantankerous means, and DRock, who is really nice guy, throughout the testing and have sent them the results, along with all 5 ammo companies that gave us their testing info relative to "relubing" between brands etc.
For what they are designed to do they both do very well IMO and IME and I don't worry about safety on either.
