Because of the type of woods I hunt in, my rifle is sighted to be dead on at 50 yards. If the top of the front sight is " in the notch" and even with the top of the rear sight the ball will hit dead centre at 50 yards. If I put the base of the front sight in the notch, with the blade above the top of the rear sight, I'm dead on at 100 yards. This arrangement makes it easier to make the shots I need when branches are in the way at the closer ranges. Since I've only ever shot one deer at the longer range, this works for me. The 75gr of FFg in the 50 cal is a decent load, and I've never recovered a ball from a deer. Now, moose hunting is a different story. My .62 rifle is loaded with 120 gr of FFg which is very accurate in that gun, and it shoots dead on at 100 yards and I have a known sight picture for 150 yards. Personally, I wouldn't recommend hunting deer with a .50 cal and 50 gr of FFg. 75 gr will give much better results , especially if distances may exceed 50 yards.
