It could catch on as long as there are rifles and/or upper assemblies with proper twist rates of good quality for sub minute accuracy - and a good supply of good brass that doesn't go to hell after a couple trips to the loading bench - and the factory ammunition actually makes the advertised velocities.

I'm interested.
We have target positions well past 1000 yards here on our personal range. I enjoy working in the wind. If this thing is really up to snuff it could be a great long range cartridge for the kids.
