Glad to see you guys appreciate the .222 Rem.
I've had one for many years. As already noted, it'll shoot a variety of bullets well.
My favorite is the 52 gr Berger over 19 gr IMR 4198 w/ Rem 7 1/2 BR primer.
Mine will stabilize a 63 gr Sierra which is a very accurate bullet, so you don't know until you try.
