In both the .222 and .223 the 40 gr. Sierra HP and Speer 52 grain HP shoot great. They are typically 30% cheaper than Vmax' and Nosler BT...shoot as well/better and kill better.
Also try the Sierra 50gr. Blitz and Hornady SX at medium velocities (under 3300 fps).
For powder, try Ramshot XTerminator per a load from the FREE and excellent Ramshot Load Manual listing lots of info, bullets, and calibers
