i think the whole point is get lost here. if you are looking to shoot a deer with a 22-250 thats fine just make sure you hit it correctly. i think what the op is going for is a gun for a child. here are the facts, a 22-250 is just as good as a 243. example 243 shooting 90 gr bullet at 3050 fps , at 200 yards equals 971 ft lbs of energy. 22-250 shooting 62 grain barnes x a deer hunting bullet at 3500 fps at 200 yards equals 1001 ft lbs of energy. run the numbers and you will see that IF you keep a 22-250 under 200 yards and make good shoots it is better that a 243. their is nothing wrong with starting children out with 223, 22-250, or 243. them main thing is practice and skill set.
