I need some advice on choosing a scope base. Bought a new CZ 457 Varmint. Am putting it in a KRG Bravo and mounting a Diamond Back Tactical 6-24x50 MOA on it. Trying to decide which Area 419 base I need. Choice is between a 15 MOA and a 30 MOA. The Club I belong to limits 22 LR to 100 yards. Plan on zeroing at 50 yards. Which base would suit my needs the best.
