I have a chance to buy a Dillon 550 progressive relaoder complete with with .45 cal and 357 Mag. dies for $350.00 that was used only a couple of times. I don't know a lot about progressive reloaders and have been shooting .45ACP and .357 Mag a lot more and it's getting expensive. Is this a good price for this rig or should I look at other progressive reloaders. PAT.
