Feederwatcher....and all,
Thanks for the input. I'm going to look into that. Do you have any brands or specs of what you used so I have a more precise start point with this?

And I've got to say to everyone that has posted here thanks a ton for the input. I'm away from home right now, so it's hard to do research in person. I'm only going to have a few weeks to get my boots back on the ground before season starts, so this is all critical. I didn't want to buy my son a rifle too early as he has grown since I've been gone. So now my wife is putting rifles in his hands and sending me pics so we can see what fits him best. The input on here has sold me on a couple of options and I appreciate it!!! Thanks again.
