Hi, I was getting ready to post an add and noticed yours.

I do not have one for sale,but several years ago I ran into the same problem with my son.

An old gunsmith solved the youth gun problem for me and the solution may suit your needs.

I bought a Remington bdl .270, we ordered an inexpensive youth stock for it and he down loaded ammo so the recoil was suitable. Don't be afraid of large calibers such as 30-06 7mm mag etc. they can all be down loaded to comfortable recoil and still be sufficent.
My son was 12 and loved the gun,a few years later we put on the factory stock and switched to factory loaded ammo, he is now 33 and still uses it.

You can do the same with most guns and calibers and save a lot of money.

You may already have a gun you could use.

The youth stocks are readily available for most makes and models and I am sure if you do not hand load yourself you could find someone to load the ammo.

Anyone that handloads will have loading books that will give the suitable loads to fill your needs.
Hope this helps, Good luck with your gun.

Larry
