Shawn Carlock built a 338 Laupa for me with a 30" ABS Carbon Wraped barrel. The rifle was built around the 325 grain Wildcat rebated boat tail as an extreme range rifle.It is built on a Rem 700 action and housed in a Sendero stock topped with a Nightforce 5.5X22X50 scope. Shawn shot the rifle today with the first load that he ever put together with the 325 grain Wildcat bullet and shot a .8" three shot group at 300 yards.... That's .255 MOA without working a load for the rifle..... To say that I am pleased is an understatement... We are still waiting on the Detachable box magazine that will allow a 3.9" loaded lenght,when it arrives and is installed he will ship it to me ..........Can't wait.........
