The 4 pin roller does leave a nice crimp but its alot more sensitive to down pressure than the 1 pin.

If you were using a vice jaw that didn't fit the shell, a 1000 ton press might not work until you crush the shell head. If you do rifle work, the barrel clamp is exactly like the hull clamp jaws and requires tightening with a big wrench and a lot of pressure to get it to hold with an insert which exactlyfits the barrel. I have roll crimped with both a hand drill and a big drill press and they both work easily with any of an assortment of 1, 2 and 4 roller crimpers. None of them are ever tightened more than slightly finder tignt and can be held in place on a table top by hand holding. I think the secret is simply use a jaw that fits, lube the crimper and run 300-500 rpm. I use my stationary dril press set at about this speed because that particular press is used mostly for metal work and has an x-y vise permanently mounted. I have quit using the actual crimping vice. I simply clamp the hull jaws between the drill press vice jaws and center the first hell under the crimper. From there on I can even change gauges and not have to adjust anything.
