Naw, was designed to tumble upon impact, causing a larger wound channel. That was the main reason for the 1 in 14" twist for the barrel. The original testing was done in thinner air that the later cold weather (denser air) testing revealed the flaw of the concept. The bullet was too unstable at that rifling. The 1 in 12" made it too stable in the moderate temps making the round far less lethal than anticipated.
Flash forward to when the SS109 62 grain round was introduced in the 1 in 12" rifling twist...same thing, too unstable. They tried the 1 in 7" to overstabilize but ran into premature wear issues. Settled on the 1 in 9".
Still the round is just too unpredictable.
I'd rather we just went back to the .308 and better training rather than trying to overcompensate with the inferior quantity. We can design less felt recoil into the rifles for those soldiers that are recoil sensitive.
The Galil AR308 has so much going for it, accuracy, reliability, rugged, second set of night sights (tritium), folding stock, simple toolless breakdown for cleaning (K.I.S.S.), comfortable to shoot, very good human engineering, and well balanced. It is the epitome of the Kalisnikov design.
For second choice would be the FN FAL Para.
