I have a .375 cheytac built by Lawton. The rifle is awsome but i have a problem. I live in western Oregon and the longest range i can get is 500 yards and thats hard to do becaus i have to shoot from one clear cut to another. It can take a while to find the road to get to the clear cut and it can also be dangerouse not knowing who might show up over there. My question is does anyone have one of thiese and if so do you have a range card out to at least 1500 yards? I will have a chance to shoot out to that range when i go to eastern Oregon and Colorado and it would be nice not to have to guess when i get there. I am shooting 350 Serria mach kings, 134 grns of Retumbo powder. Thanks for any help you can give me. Jason.
