The 308 case head is too big. The only case that will work is the 220 Swift and it is a lot of work. The steps are below. Good luck.
Turn the rim to .441.
Cut new extractor groove.
Anneal the case and taper expand to .318.
Full length size and set the shoulder back with the expander removed.
Trim to length.
Inside neck ream if necessary.
Full length size and fireform.
That is some work, I think I will keep looking for ammo or a way to re-barrel it into another caliber, to bad it could not be sleeved for 5.54x39, and then set up for the ak74 mags
Century Arms just got in a batch that they are advertising for sale. Also, you can purchase a chamber adaoter that allows you to shoit 7.62x39 in your rifle, and they work well.
