Ky221: Several of my 222 Remington Rifles prefer the wonderful yet humble (and its a Spitzer) Sierra 50 grain Blitz bullets (not the BlitzKings).
I have shot amazingly small groups with these bullets especially from my Remington 40XB-BR in 222 Remington.
They also perform wonderfully well in the Colony Varmint fields (Rock Chucks on down) along with spectacular results (terminally) on Crows and some other types of flying Varmints.
Have not done as much in the way of Predator Hunting with them but have on occasion with no complaints.
Be sure and try these out in your 222 - and they are a bit cheaper than many other bullets.
Good luck with whichever you choose.
Hold into the wind
