Some interesting data

Just noticed that looks like a single shot? Is that a single shot? Please tell me you didn't let that child hunt with a single shot . Why, I should think he would need at least 5 rounds in case he missed, especially with such a small bullet. Alright, next tome he needs a 300 Super magnum special long range custom magnum magnum, in a semi auto with 3 extra mags attached to the butt stock and 2 in his pocket. Must be equipped with a 1.5-40x60 super ranger, Bullet Drop Compensated, Mil-Spec, laser equipped, red dot superduper scope.....mounted in aluminum high/low scope rings of course! :D

Both my kids learned on a single shot .243. Single shots are great for kids to learn with. They have one shot and have to make it count. I guess this kinda proves your original post. Its really more about placement than caliber.
