FAQ’s
- I don’t see my cartridge listed in the collet chart, what collet do I need?
- Each collet fits multiple common case rim diameters that relate to the steps inside the collet. For example, Collet #1 fits .379, .473, or .532 Diameters. To select the right fit for your specific brass, measure your case at the rim/head area and choose the collet step that matches best.
- Can I use the same collets from my Henderson trimmer on the MatchMaster trimmer? What about the pilots??
- While the collets are interchangeable between Henderson and RCBS trimmers, the pilots are not.
- Can I use my Trim Pro or other RCBS pilots, collets, or 3-Way cutter heads with the MatchMaster Trimmer?
- The MatchMaster cutter heads, pilots and collets are newly designed and unique. So no, older RCBS pilots, collets and cutter heads such as the accessories from the Trim Pro series are not compatible with the new Matchmaster trimmer.
