New rifle

[skeet]

When doing the gun show this last weekend i took an as new in box(shot 1 time)Remington 700 Classic on trade. It is in a really neat caliber and i want to figure what scope to put on it. The caliber is 221 Rem Fireball. The scopes I have available right now are a Leupold VX II 3X9 with regular Duplex and a nice Nikon 4.5X14 . I am leaning to the Leupold 3X9 but am not sure what the effective range is with that caliber. I was thinking I didn't need the 4.5 X14. I'd like to get some other opinions. I also found a 12 in Contender bbl in 218 Bee. Wondering if it is wothwhile to have? What are your opinions on both??
