Unzipping the Zipper

The .219 Zipper persisted fitfully from 1938 to 1962 in that purgatory reserved for cartridges that look good on paper but somehow never quite measure up in real life. At this late date, it’s difficult to determine exactly how the .219 Zipper ended up on the compost heap of shooting history.
