My 13 year old just got a Bergara B-14 HMR 6.5CM with a Burris XTR 3-15 on it. First time shooting it he went 4 for 4 on the 18" plate at 1045 at CRC with factory ammo. He is only 5'1" and 130 pounds and does fine with the recoil. He shot the NoCo Precision match in January as his first precision match and finished above the others that were shooting their first and a few of the regulars. That is a great package for not a lot of money.

He does not have a tri-pod yet, but he borrowed one on a few stages. The CRC match on the 4th Saturday is probably the most beginner friendly and Raton is probably the most challenging, but I would not worry about it. Pick the one that fits with his (and yours) schedule and get out there.
