I picked up a used 550, and it came with these, but I don't reload this caliber. So, they're up for sale.
Dillon .45 ACP 550 Conversion kit. Shows wear and age, but appears completely serviceable. Includes shellplate, powder funnel, and locator buttons, but no box.
Dillon .45 ACP dies. These appear to be an older style, not the new style pictured on the dillon website. Again, they show wear, but appear completely serviceable. No box for these, either.
$75 OBO for the pair, shipped to the lower 48.
