Brent, with that combo you'd better tell your son to wait until the deer has walked quite a distance away from him!
I shot a measly(but tasty) four point at the really long range of 40 yards, and the critter instantly developed a fist-sized hole through its lungs......from a "pee-wee" .308 Win!!! Your son will love that particular bullet's performance---guaranteed!
A little off topic, but I just remembered now that all the 300 Ultra loads I shot on New Years at 0 degrees were loaded with 210m primers, they all went off without a single hitch. Cool! Thanks for the tip guys.
