Interestingly the 219 Zipper started as a necked down wildcat of the 25-35 Winchester WCF until it was put in production from 1937 to 1964 by Winchester. The 219 Improved Zipper is basically a blown out 219 Zipper case with a much steeper angle on the case to neck, from 13 degrees to 26 degrees more powder and power. This makes the 219 Improved Zipper a Wildcat from an Obsolete Cartridge; due to Obsolete Headstamp they are a little pricey. I will try to get some made from 30-30 cartridges in the future. |
