Yes, you clearly don't understand the mechanics of taking a rifle, aiming it at someone and pulling the trigger.You really have to respond to Caudecus. (or what his name is again) A lot of weird energy from the delusional Trump-crowd currently. I'm having 50 conversations at once here. Most I've talked to seem surprised that he managed to inflict a "razor cut" to Trumps ear with a supersonic rifle bullet, and then miss all rounds after that. Recoil/wind etc. has nothing to do with it. You can wait a sec and aim again etc. I don't know what happened, but Trump sure is one lucky guy. Not many people in history have been that lucky I must say!
However, the people on here who have done that professionally have explained over and over again why such things as recoil, wind, rifle, barrel, scope, breathing, adrenaline, powder load, experience, target movement and a bunch of other factors effect shooting at someone.
The fact that you don't understand or believe them is your failing, not theirs.
