I love pigman, my kids and i watch him every week, i too have been trying to get some info on that gun. i think he has both a 300 and a 338 version, he shoots 208 grain hornady amax. i think the advantage is that you can use a lapua action instead of the cheytac action and get similar performance with a lighter set up. i own the 338 cheytac version and it weighs alot around 14 pounds scoped. i just sent pigman an email hoping that someone will respond to my email about the gun.
