OK, 270 Winchester ballistics, but in a light weight poly cartridge that gives those speeds in a shorter barrel. No doubt the round will be lethal. A 94 year long track record of those ballistics is beyond argument.
Sounds very interesting, but I want to see how the new rifle will deal with the heat of such power and pressure.
I remember seeing a report on a new barrel steel that was used to fire a string of uninterrupted fire from an M-60 of just under 1000 round in one pull of the trigger, and the barrel was not harmed.
Maybe that is the direction they are going?
To me, the technology is interesting. 3100 FPS cannot be achieved with 135 grain bullets in short barrels without some heat being generated, so where is that heat going to go?
