Forster Precision Bushing Bump dies. Size the neck, bump the shoulder as needed and throw in a body size when the bolt starts gettintg snug on opening and closing and you're good to go.
Swap bushings and with the same die and you can do 22 BR, 6mmBR, 6.5BR, 7mmBR and 30 BR. Havn't tried in with anything smaller, "yet". ;D Also works on my 6.8 BR Wildcat with no problems.
