The 219 DW is a very good cartridge and in works well in the Handi platform. You can purchase a 22 Hornet barrel and chamber it to the Wasp. You will be stuck with the twist rate of the 22 Hornet, 12" for the older Hornets and 9" for the newer ones, real old ones might be 16" twist. You can chamber a 22 Magnum barrel to the 219 DW, but it will have 16" twist and the barrel material will be made out of different steel alloy that the 224 centerfire barrels. The 223 is a bit too long to be chambered in 219 Wasp. Another possibility is to get a 17 caliber barrel and have it bored to a .224 and then chambered to the 219 DW. One advantage to that is you can get a twist rate you wish. The other way is to find a donor barrel (usually shotgun) and get some one to stub it with a .224" barrel and chamber it for the 219 DW. The stub should work, since it can be chambered in a T/C Contender. Another possibility is to chamber a 223 into a 219 Zipper or a 225 Winchester. Of course you still be stuck with the twist rate of the original 223 barrel, again 9" or 12" twist rates, depending on age. There are a few of them around, I think Stimpy may have one, but not real sure on that. Since you already have a Wasp, I do not have to warn you about the problems of making cases. Making cases aside, the 219 DW is a very good cartridge.
Good Luck and Good Shooting
