RCBS MatchMaster Competition 6.5x55 Swedish Mauser Seater Die

A single MatchMaster competition seating die for 6.5x55 Swedish Mauser. This is the seating half of the process on its own, for a loader who already has a sizing die for the cartridge or who wants to change only the seating step.

Competition seating dies support the case and the bullet in alignment before the bullet ever starts into the neck, which is where crooked ammunition gets built in or kept out. On the 6.5x55, with its long case and the long bullets people load in it, that alignment is what you are paying attention to. Seating depth adjusts from the top of the die, and once it is set the die repeats it.
