Bought a roll crimper on eBay that was listed as a 20 gauge, but when it came it was a 12 gauge. I do not load TSS in 12 ga so I do not need it. Seems to roll very well on some empty used 12 gauge hulls. Keeps you from needing a drill press to do beautiful crimps.
Asking $45 TYD. Feel free to pm questions and references available upon request. Thanks!
