.22-08?

[Macchina]

I know the .22-250 exsist, but it's parent case is the .30-06. Is their a commericaly avalible .22 cartridge that is based off of a .308 case? I've had a .243, I am currently shooting a 7mm-08, and everyone know the .308 is a great cartridge, but I haven't seen a .308 necked down to .22. Does anyone know if one exsist in production, or if a wildcat has been tried out.

The 22-250 is based on the 250-3000, which is in the 308 line of cases.
The 308 family

Yes, on a wildcat basis.
It is normally done on .243 brass to make the neckdown easier, but the .243 is just a 6mm-08 so the end result is what you are talking about.

Pac-Nor chambers for several versions, plain .22-243, Middlestead, and Ackley. I say Pac-Nor because they will fully chamber and thread a barrel for DIY installation on a Savage locknut action; not a difficult procedure.
RCBS makes dies for all those versions.


Gee, Brian, I do not consider the .22-250 to be part of the .308 "family" considering that the parent .250 Savage predates the .308 by about 30 years. It has the "standard" head diameter which goes clear back to the 8x57 of 1888, but it is a shorter case and not otherwise related by my criteria.
