I heard what I consider a very wise comment from an older and wiser man than I: "Always hold on meat the first shot". If your gun is sighted in normally (1-2 inches high at 100 yards) this should hold true out to normal shooting ranges.
......
Therefore, I feel that if you always hold on "meat", and the angle is steep, if you hold low on the body, you will be ok because the bullet will go above where your crosshairs are.
Wow that is some convoluted logic. If it works for you then fine. Myself I like to know what is really going to happen. Its not as hard as folks try to make it out to be.
If you are sighted in 1-2 inches high at 100 yards with an average hunting round then you have a true zero of approx. 200 yards. Obviously its different from cartridge to cartridge. Now in your example you said that your brother took a 300 yard shot at a deer at a steep angle.Well that 300 yard shot I would estimate should have been shot as if it where a 250 yard shot. A rule of thumb I use is 80% if its really steep (either up or downhill). So your theory would be wrong. If you are sighted in at a 200 yard zero, then the bullet would not impact higher than the point of aim. It would hit lower than the point of aim, just not as much lower as a true 300 yard shot.
