From the June American Rifleman, page 64.
Western Powders Reloading & Load Data Guide.
"Loaded in the higher-pressure 5,56x45 mm NATO cartridge, the same projectile reportedly hit 2701 f.p.s. with a pressure of 60,052 p.s.i. virtually identical to the .224, so performance will be similar"
Projectile was a 90-gr HPBT MatchKing.
So don't run off and throw your 223 bolt guns away.
Just go buy the Western Powders Reloading & Load Data Guide.
If it makes you feel better take a felt tip and write Valkyrie on your barrel.
For AR guys; If you own a 6,8mm SPECII just load 90gr HPBT.
