The diminutive 218 Bee is a member of the 25-20 and 32-20 family of cartridges.  Introduced in the Winchester model 65 lever-action rifle, it never achieved much success.  It can sometimes be found in various single-shot rifles and for a short period of time Winchester chambered their model 43 for it.   The price is per 50 cases and the shipping weight is 230 grams.
