Have fun with her, the .222 is a beutiful little round, I have punch some TINY holes in paper with that cartridge before with a 14" T/C contender bbl. No matter how well I did on my part, I always felt she was just sitting there waitn on me to do better.
I have some great loads that I worked up in the 14" barrel, Im sure they would do about the same in the 10" (may have to modify a lil, but Id be happy to share recipes if youd be interested, let me know)
