Magma Engineering, of Queen Creek, Az., makes a Sizemaster Jr., for taking bulged cases back to factory specs. It runs the fired brass base first through a carbide die; I hook a Dillon case feeder to it, and can do about a thousand an hour.

At $325, its not the bargain unit, but it sure does work great. To be safe, I do not use these brass for top end loads, but have many, many mid range loadings on them before they split like any other brass.
