I have a 308 and call myself a good shot.But im not gonna take no 775 yard shot at a deer. I can shoot with most people at 300 to 400 yards.But im not waisting my money on bullet,s just to be slinging at an airball.much more it,s hard to see a n animal at that distance, unless it,s a elelphant.im not saying it cant be done,but it has to be someone with very expensive gun and scope.the 308 browning bar is as good as gun they make with a leaopold varix 3 scope. I will leave it to you expert,s to shoot at that distance.
