17/222
Historical Notes:
The 17/222 is simply the
222 Remington
necked down to 17 caliber. There are several versions of this cartridge,
but this one is the most popular. The 17/222 dates back to about 1957, possibly
earlier. Many shooters considered the 17/222 more accurate and less sensitive
to load variations than the wildcat 17/223, which was the forerunner of the
later 17
Remington. P.O. Ackley considered the
222 Remington
case about maximum capacity for the 17 caliber and states it in his book,
Handbook for Shooters and Reloaders, that larger cases tend to be
inflexible. Those who have experimented with larger cases have usually found
him to be right.
General Comments:
The 17/222 did not achieve great popularity, but was well liked by those
who worked with it. Performance is practically the same as the
17 Remington
which has a larger case. Best accuracy is usually with
IMR
4198 powder and the 25 grain bullet. Recommended twist is 1 in 10 inches.
Cases are simple and easy to form by necking down
222 Remington
brass with no other modification. There has been some renewed interest in
this cartridge during the last couple of years.
