Has anyone done a .20cal wildcat on the 22 Hornet or 218 Bee case? If so, know of any data or specs?

Thanks in advance.

There have been work done in .20 in both calibers. James Calhoun calls his Hornet based cartridge the .19 Calhoun. The .20 Bee cased wildcat is reffered to I believe as the .20 Killer Bee. Small Caliber News has done several articles on these wildcats. You may also contact Todd Kindler at the Woodchuck Den in Baltic OH. 330-897-0614.
