RCBS “Brass Boss” Case Prep Center with Six Stations

RCBS has a good successor to the venerable RCBS Trim Mate. The RCBS Brass Boss features six rotating stations that handle all your brass neck-brushing, chamfering, deburring, and pocket uniforming chores. The RCBS Brass Boss includes tools for all six stations: inside VLD chamfering tool, outside deburring tool, primer pocket cleaners (small/large), military crimp removers (small/large), primer pocket uniformers (small/large), case neck brushes (four diameters), and a tub of dry case neck lubricant. MSRP for the Brass Boss, RCBS Item 90390, is $219.99. The best price we found is $169.99 at Natchez — a very good deal.

This machine has two different rotation speeds for the toolheads. Four stations run at 350 rpm, while the two other stations run 57% faster, at 550 rpm. That give you a choice of spin speeds. You can work fast for tougher chores like military crimp removal, and slow down for inside-neck chamfering, which should be done carefully.

Larger and taller than the older RCBS Trim Mate, the Brass Boss has one more station (six vs. five), plus a more powerful motor. This should make the Brass Boss more competitive with the popular Lyman Case Prep Express.
