Range Report Trom Tech

Lots of meh video, lots of claims....no specific data on what makes their ammo different other than, "your hit rate will improve over NATO spec rounds".
I get that it appears to be well-made ammo capable of higher accuracy- but why?
 
According to their data sheet for .308 Win, the bullets are "Monolithic Brass" - so, solid brass - no jacket, no lead.
135 gr. - 2885 fps from 20" barrel. Doesn't mention a BC, but does show a chart showing 10.8 mils at 1000 yards. Goes subsonic between 1000 and 1100. Pricey stuff though.
