just too much stuff that aint true in this post. just ("poor") opinion.
the swiss k31 is the peak of mil issued bolt rifles.
there are claims of 308 mn's but in over 20 years of owning selling competing I have NEVER SEEN ONE.
AND YES I OWN A 28-30...the spec is 309 not 308.
lots of real production 308 win rifles have been made in 12 and 11.xx twists. the trend to day is a 10.
my armalite ar10(t) 24" is a 1/11.xx
pretty sure this dates back to thinking a 168 was the perfect bullet for 308, which it aint.
opinion by a guy that owns several mosin nagant rifles, swiss k31 and 4 ar10's. shooting and winning matches for fun.

Some basic physics apply in this discussion . The OP is asking about a AR-10 . A .308 caliber . Pretty well accepted that for most applications , a 1-10 twist barrel is more than sufficient for the majority of bullets used in a .308 , for the majority of comp uses . The reality is that a 1-9 1/2 is actually a better twist rate , but creates other issues . One being cost of mfg. since it isn't a twist rate in common usage . A example is the Finns made their version of the Mosin - Nagant in both a 1-9 and 1-91/2 .308 twist rates , and they are still considered to be one of the most accurate military rifles ever produced . And most highly prized by M-N aficionados . But when have you heard of anyone making a 1-8 twist rate . 308 barrel for any application ? It boils down to diminishing returns . As has been learned by both shooters , and manufacturers decades ago . 1-8 twist rate barrels were designed to keep smaller diameter , lighter bullets stable for longer distances . Physics haven't changed since the AR was created and you have to ask yourself why Gene Stoner created a near perfect combat weapon in .308 to start with ? And the bean-counters , and politicians , and special interests turned it into a "High-powdered" B.B. gun . Think the "KEY" word in the last sentence was "Special interests" . But what do I know ? I'm just a two-tour Nam Vet that can tell you more about that POS than you want to know . Sorry ! Rant over .
