There is tons of posts regarding the 222 Rem.
I've posted this on most of them. One of the most popular and best loads (seems very good in almost any rifle) is 50gr Hornady SPSX's loaded over 20.5gr of 4198.
I have tried tons of different loads in my 222's and this load is always one of the best.
I did however try CFE 223 with the SPSX bullets and got practically the identical tight groups. 26.2 gr of CFE 223 i believe is the max (please double check). I did load a bunch to 26.5gr and on a hot day I was vaporizing the SPSX bullets. They can't handle 3400+ fps.
I also have a great load using Barnes 36gr Varmint Grenades over 322 powder. I will look it up tonight and post it. Super groups, (<1/2") and screaming fast. 3800-3900 fps.
You will love your 222, they are relatively easy to get good accuracy out of, and they are fairly economical to reload for.
