.17-223

About 1945 the first .17 caliber wildcats began to appear. The idea of a subcaliber .172 diameter bullet was first developed by Charles O’Neil and P.O. Ackley completed the barrel tooling. But O’Neil never completed the cartridge design.

P.O. Ackley and associates are credited with the first .17 caliber cartridge when they necked down an M1 carbine cartridge case and called it the Ackley Pee Wee. This led to development of.17 caliber cartridges using numerous parent cases including the 223.

The .17-223 is capable of propelling a .172” dia. 25 grain bullet at approximately 3,989 fps with 883 ft.-lbs. of energy. This is an excellent varmint caliber and it has taken down sheep, deer, hogs, prairie dogs, woodchucks and other game. It is recommended as varmint caliber rifle.
