.223 or .243
But now I'm leaning toward letting the 9 year old (85lbs) shoot the .243, and skip the .223 idea. The LOP bothers me, but should I overlook it? Am I over thinking it?
If he uses the .243 (completely under my supervision, with a rest/brace) should I dial down the grain? I think .243 goes all the way down to 55, but I'd be scared to use anything smaller than 85 on a deer.
I hate to buy a gun when I already have one.
