Zipper

The .219 Zipper was introduced in 1937 by Winchester in the Model 64 rifle. It is based on the .2535 Winchester case necked to .22 caliber. The Model 64 lever action rifle did not prove sufficiently accurate for long-range shooting and did not allow easy use of telescopic sights. Winchester discontinued .219 Zipper ammunition in 1962 and Remington followed suit shortly thereafter.

In a single shot or bolt action rifle, the .219 Zipper was considered as accurate as any other .22 centerfire cartridge in its class. When used in rifles with tubular magazines, bullet selection is limited to flat or round nose points thereby limiting long-range performance.

There is no longer a SAAMI specification for .219 Zipper ammunition. Because it is based on the same case and used in the same type of rifles as is the .25-35 and .30-30 Winchester cartridges, a pressure limit of 42,000 P.S.I. was used by Accurate Arms' technical staff.
