Was going thru some 7mm Remington BRbrass, thinking about forming to 6mm BRX. Too short in the neck, but the 6mm Remington brass was fine as far as OAL. What caught my attention was some brass was marked 6mm Rem Br, some 7mmRem BR and some just had Rem BR. All was new brass. All the brass over the years I have seen has had 6mm or 7mm on the headstamp. Maybe the non caliber designation was from an early batch of Br brass. Just thought I would share.
