Quote:Just out of curiosity, but are 22 Long rimfire cartridges still manufactured? It is my understanding that although the chamber length for the Long and the Long rifle, is the same. The actual twist is different between the rounds and that Long Rifle does not shoot as accurately as the original Long round if used in the earlier models chambered for the long round.

Harry,
Here's a link to CCI.
(You need to Login or Register to view media files and links) I could find only two versions of the 22 Long that were loaded by CCI, a HV loading showing a muzzle velocity @ 1215 fps, and a CB loading showing a muzzle velocity @ 710 fps, with both versions using 29 grain bullets.
The old WRA catalogs I have show that Winchester loaded the 22 Long cartridges using 35 grain weight solid-nose bullets or 32 grain hollow-points, so the CCI Long cartridges are currently using a bullet weight that WRA used to use for the 22 Short.
Campbells first singleshot book shows that WRA used a 1:24 twist for both the 22 Long and 22 Short, and shows a 1:16 twist for both the 22 Long Rifle and the 22 Extra Long.
Interestingly, the book also shows that for the 22 BB cartridge, Winchester used a 1:20 twist.
On a side note, I always get a chuckle when I see the old WRA cartridge listing for the 22 Short "Spotlight" cartridge, and wonder if those cartridges were any better for the purpose of jacklight shooting.
