Oh, it's a magical round....
Yep. Magical in its velocity gains, seemingly in violation of the laws of physics (or maybe guys are just loading the 223 Ackley to higher pressures
).
Is the 6 Dasher magic too?
TONS of competent reloaders pushing that cartridge to .243 speeds (long bbls, I know) and yet the .223AI is the magic one I guess.
As a reloader, I look for sticky bolt lift and primer pocket longevity as that's all I've got to go on.
.223AI formed brass, 75 ELD and 8208 will bump 3,100 fps in a 21" bbl with long brass life.
Hodgdon states 2,800 in a 24" bbl with a 75 JLK fwiw.
So if I back down to 3,000 fps is it still magic?
