Is there any updates on this? Did Mr Kirby ever go through with this? If so, results? Also, has anyone here shot a .416 Barrett? What was velocity/accuracy like? I havent much good things about it, havent heard much at all really. Same for the .460 Steyr, has anyone shot it? Also, has anyone shot or bought a .375 Viersco Mag? Is Mr Viers done with it yet?
