Hi Everyone,

Question: Can .220 Russian brass be fire formed to function in a 6mm BR chamber/rifle?

Thanks in advance for the help

Case head diameter for the 220 Russian is .443", the case head diameter for the 6mmbr is .469".

It is not possible to fire form a 6mm Remington to 6mm br. To go from 6mm Remington to 6mm br the reloader must become a case former. First from the case then fire. Fire forming is a matter of chambering a round and pulling the trigger. There is necking up and necking down, when necking up and or down RCBS says 'no forming die necessary'.

What does this have to do with a 6mm rem?
