lots of good suggestions on here so far... I've been eyeing a cva scout 243 online they'd probably be ballpark 350 in hand maybe less if you didn't want stainless. they also come in 300 BO. they have bergara barrels. and would be a decent option on price.. other than finding a cheap scope. BUT, honestly if you're really thinking on price. you might could catch a used axis for cheap or try an SKS, ammo is easy to find, accuracy and recoil would be fine, and the round would work well for the distance a 9 and 6 year old could manage... just a thought.
