I'd stick to weights under 53, especially in 222. No, I have fired a few and the 60 gr. Parts will not spin worth a hoot in a 1-14, even at 3,400 fps in a 222 Magnum L461.
If going to a hunting bullet, the Barnes TSX 45gr. will work.
40's and 50's of all flavors are loved, as are most powder combos. 222 powders to use are Rl-7, Rl-10x, 4198, Benchmark and a host of others.
