Re: .219 zipper improved

It is .22 caliber, although the custom rifles back in the day were often but not always made on re-chambered .22LR barrels with about a .001 smaller groove diameter and 1-16 twist. You can use .224 bullets but the .22LR barrels were designed for .223 bullets. The case is a necked down 30-30 so it has a rim. It will not work in most modern bolt action rifles. There were many improved versions including the 219 Donaldson Wasp. The 219 DW was one of the first "Benchrest" cartridges.

If you have a 1-16 twist you will be limited to 40-45 grain bullets (maybe a little heavier) and velocities will be in the 3200-3400 range depending on what you want to do.
