Background:
I am in the process of building a 11.5" PDW that I am calling "Tinker". I got a Noveske (Pac-Nor) 11.5 barrel because I found the improved polygonal rifling was better than the single point cut/traditional rifling which would provide a better gas seal thus higher velocity and because it was an "improved" version, it would have increased accuracy in a 11.5" barrel. Also, Noveske/Pac-Nor guarantees these 11.5" barrels to have tolerances within .0001 and .0003 and each barrel is hand lapped.
Having said that. I am looking for a specific bullet (5.56) for this particular barrel. 11.5" 1 in 7" twist, carbine gas system. I don't have any requirements other than absolute surgical precision, accuracy and consistency up to 300 yards and 2000+ fps and low frag velocity. I have looked into the following:
Barnes 85 OTM
Black Hills 77 TMK
Barnes 69 OTM
I know nothing about bullets. I don't even know what is available. Any thoughts? Are any of the 3 that I mentioned good?
