[QUOTE="LouBoyd, post: 601019, member: 9253"] 223 WSSM - Much more case capacity than a 22-250. Barrel life is limited. Like other high velocity "varmint" cartridge it can cause explosive surface wounds. 243 WSSM. - Similar*to a 243 Win in a standard short action magazine. Low wind deflection. 25 WSSM - Similar* to a 257 Roberts in standard short action magazine. 300 OSSM - Similar* to a 308 Win in a standard short action magazine. Highest short range energy. Longest barrel life. OSSM brass is made by necking up 25 WSSM brass. *None of them can shoot heavy low drag bullets limited by magazine length. the 308 OSSM is limited to 150 grain BTs. All require special magazines for use in an AR-15. I'm not sure what you mean by "build". You can buy uppers which fit standard lowers from Olympic arms. I don't know of anyone who sells complete barrels, barrel extensions, or bolts separately. Accuracy Systems offers custom uppers. [/QUOTE]
