Congrats, and I think Bass Pro has a Remy in 243 youth in their Fall Sale. I can't remember how much, but it comes with a 3x9 scope already mounted. I think it was around $400? I was thinking about one for my kiddo.
Doo eeeeettttt!! The great thing about the youths is you can swap the stock when they get bigger and now they have a grown up rifle!!! Oh, and .243 is an awesome caliber for deer...Just ask this guy:
