.223 pressure Gold Dots from a 14.5" barrel

I think the ability of these rounds to expand at .223 velocities (as opposed to 5.56 NATO speed) is in the same vein we are seeing with modern handgun ammunition, namely the HST line. i.e. you don't need screaming velocities to make bullets function anymore with modern bullet designs.


ETA: The "need for speed", even with well-designed bullets, is more important in rifle cartridges as it is in pistol ones. For handgun ammo you're not looking at the variations in distance like you could be with a rifle load. That translates to a higher muzzle velocity necessary to give the specific bullet more RANGE in which to function as designed. For a handgun you're looking at usually well inside 25 yards; for a rifle/carbine you're expanding that to 25-100-200-300-etc.
