.223 Barrel Lengths

[Jackalope33B]

Does anyone have a chart that shows the Velocity of a .223 round for different barrel lengths? Im in the market for a SBR 9"-11", and need to know what my velocity will be approx. Also, what will be the max range and still be accurate for these short barrels to still have some effect on a target?
