I was watching a video where the guy said he wanted to be a little low @ 5 yards so it would be dead-on at more typical ranges. Without regards to the typical self-defense shooting range, does a bullet "rise" after 5 yards (out of a handgun...or even a rifle)? I assumed it came straight out & did a slow drop, but I'm no physics major, or better yet, an ammo guru. Please give me the low-down. Thanks.
