the military snipers just performed a test of all available long range calibers. The .300 PRC won by far. So on paper there are many choices it just gets interesting when some of these new calibers get put to the test. I am sure there are hundreds of opinions on this but it’s neat to know what is really on the cutting edge.
I've read that is was more so designed with a group of them, so Hornady catered to their specific wants and needs. Smart on their end, making the cartridge to the desires of the people evaluation. That combined with an American company and its field results just make for an easy win.
