Based on the .219 Zipper case but with a reduced rim diameter[2] to fit the common .473" bolt face, it was intended as a replacement for the .220 Swift cartridge which had a reputation for burning out barrels.

Despite having a modern straight taper design, the round was eclipsed by the older .22-250 Remington, already a popular wildcat introduced commercially a year later.

All commercially produced rifles chambered in .225 Winchester were turn-bolt or break actions.

The .225 Winchester's case is a parent case for some of SSK Industries'[3] popular line of JDJ cartridges designed by J.D.

Jones, chosen for its strength and semi-rimmed design which makes it well suited for use in break-open actions.
