Thread: Shorter Barrel 223 data

@Hahn

It really depends on the gas system too.

Rifle length, mid length, carbine length or pistol length gas systems.

14.5" was another common length too but alas no more.
@Tentman I do recall looking at 223 data and it showed in the heavier bullet weights especially like 62+ that gppd old 2208 gave better fps than 2206H
