[QUOTE="LouBoyd, post: 847326, member: 9253"] Consider not only supersonic range but also wind deflection in choosing a long range cartridge. My longest range AR-15s are: 6mm PPC - M1S 243 WSSM - Olympic 6.5 mm Grendel - Alexander Arms All have 24" barrels All can reach 1000 yards supersonic, at lest where I shoot in Arizona. All can feed from a standard AR-15 lower though they require slightly modified magazines. They are not the same though. The 243 WSSM has the flattest trajectory but the worst wind deflection. There are no doubt some wildcat cartridges which can do as well, maybe better. The 300 OSSM isn't close to a 1000 yard cartridge. In an AR-10 I don't consider the 308Win/7.62 NATO to be a 1000 yard cartridge. The 6.5 Creemoor gives the best range & wind deflection performance of any commercially available AR-10 cartridge I'm aware of. [/QUOTE]
