22-250 Remington: .22 Caliber
Remington has a long and successful history of bringing popular wildcat cartridges to “standard cartridge” status by locking in dimensions and pressure and velocity assignments, standardizing names, and submitting to SAAMI. One of these is a premier varmint cartridge: the .22-250 Remington.
As the name implies, this is the .250 Savage case necked down to hold .22 caliber bullets. In its commercial incarnation, the .22-250 shares almost every dimension with its wildcat parent except for an almost imperceptible 1.5-degree difference in shoulder angle. It is an elegantly simple conversion.
The history of this cartridge in its wildcat days is cluttered with conflicting information. Many experimenters in those days were working with the .250 Savage case. Some of the best information I found is almost contemporaneous to the cartridge. Phillip B. Sharpe’s classic Complete Guide to Handloading was first printed in 1937, and Sharpe later added supplemental sections. J.E. Gebby developed the version he called the “22 Varminter.” Other references suggest Gebby’s final version appeared close to Sharpe’s first printing.
Sharpe is very complimentary of Gebby’s diligent attention to detail in the development of the cartridge. He says Gebby retained the .250 Savage’s 26 degrees, 30 minutes shoulder angle, considered fairly steep in that era. However, what drove me to drag out my well-worn copy of Sharpe’s treatise was velocity.
