Bullkllr, I agree with all of the above. I am in the same position you are. I have narrowed my choices down to the .25-06, .257roberts, .260 and 7mm-08. I don't feel comfortable with the .243 and I would definately stay away form the .308 as a first gun for kids! Out of the four the 7-08 has the best availability and widest selection of factory ammo. Unless you handload I would go with the 7-08. If you do handload (or know somebody who would do it for you) then just flip a coin, see what's available in your price range, and which one has the best fit as far as size. You (and the boys) won't be disappointed with any of these. Personally, I'm going to see what fits my son and what I can get the best deal on. I will feel confident with any of the 4 calibers I mentioned.
