Ray,
I brought my new 6.5 Mag home last night. I hope you look into these as a gift for your son. As a close-out, they are reasonably priced at this time. They came out in 6.5 mag, .308, .300SAUM, and .350 mag. With some Special Runs in .243. As a short action rifle, they are hard to beat. The .308 would be by far the cheapest to shoot.
You may want to check the shape of the grip first. Some people don't like that sweeping grip.
