I'd have to make it a Muzzleloader to make any of that stuff fair.
One time, I was in a Capture The Flag game, one guy got into our base, took the Flag, jumped into a Stunt Plane, and took off. I shoot a few times at him with an Assault Rifle, but he got to a point where the bullet drop, his distance, and his movement were making it very hard to take him out. To win this game, your Team needed 1000 points, boths teams only had like 180-200 kills at that time, but the flag was worth 1000. Take the Flag back, you win. So... I reluctantly went to the weapons shelves, grabbed a Military Sniper, and quickly shot his ass down. He was little more than half-way to his base, and I felt like stuff.
