I just bought a 22 Mag sportster barrel. While it is being shipped I have began to ponder a rechamber to 218 Bee and fit it on an SB2 frame. Is there anything I am missing in considering this rechamber? I have owned a couple of Bees over the years and really enjoyed them. A Hornet is too long to rechamber to Bee. From your experience, what would this rechamber and extractor modification cost? I have also thought a little about 221 fireball....I like things a little different.
