CM7,
Sorry I didn't see this post earlier. I Bought a used 222 Rem from a competition shooter who sold it because it won't shoot as well as he wanted. He was an excellent record keeper and I received target and load for every round fired. He used all of the powders mentioned above.
I just hunt and all shots would have been good enough for me, but I had some VV N-133 and started loading with it. To drag this out a little more it shoots little over 1/2" at 200 yards in tight little clusters, rarely over 3/4" it is the most accurate rifle I own and using 50 gn VMax, not the Match bullets you'd expect.
i'll be quiet now :lol:
