Nothing wrong with a 22-250 for deer. With a .243, like many have said, no need for reduced recoil ammo. When my daughter started shooting her Remington Model 7 when she was 12, I put a Sims recoil pad on it and she never blinked. She's now 15 and I'm thinking of stepping her up to 7mm-08 or .308, just haven't made the decision yet, and she loves that .243.
