If so, what size bushing? I?m reading .266? most places for 6ARC and other 6mm. Going to get some calipers on some ammo tomorrow but wanted to see what anyone else was using.

I normally use RCBS dies but got Hornady brand match dies with the seating micrometer and ELD stem so the requirement of the bushing in the sizing die is new for me versus an all in one expander mandrel/decapping pin assembly

Any other 6ARC lessons learned are appreciated
Thanks!
