Hcpookie we are on the same page. I would not trust a lot of that old 8mm ammo out there plus I hear that it is really dirty and corrosive. I am going to do the 308 first plan on shooting it with NATO loads for fun and hand loads for hunting. If I get the mag and feeding working I would probably build a 358-08 for a heavy pistol round http://www.hodgdon.com/data/rifle/358win.php. and a 243 for varmits. the only differance would be the barrel as they all use the 308 parent casing. 7mm-08 is another good choice as well. just bought 3 more yugo gits it beter work.
