so if you shoot straight up or at a slight angle the bullet will go just as far if it is a .223 22 or shot shell
No shotgun pellet is ever going to travel as far as a rifle bullet will. PERIOD! And, think about it, would you rather have a #6 shot pellet, a single pellet, hit you or a bullet from either the .22 lr or .223. The pellet is NOT going to penetrate near as deep as a larger, heavier chunck of lead/bullet. The shotgun pellets all disperse, so the likelihood of gitting hit by more than one single pellet is nill. It's like would you rather be hit by a bike or a car. the heavier object, going the same speed, is going to have more energy and, hence, will do more harm!
Don't you know the difference between a shotgun shell and how it performs when compared to a rifle. To say the shotgun shell pellets are more deadly is ludicrise, unless being shot from a very close range before the pellets have a chance to disperse. No way, no how. The pellets quickly disperse and loose thier energy. A bunch of pellets at very close range, yes, deadly. BUT we're talking about shooting up into the air. By the time the pellets start coming back down, some of them hitting a target, some of them hitting tree branches, they have gotten so dispersed, that it ain't going to kill someone when they return to earth. Being struck by one pellet is NOT nearly as dangerous as being struck by a bullet. You can look it up all you want, BUT IT AIN'T HAPPENIN!
