Cool to see this thread going. I ended up going on a 224 barrel buying spree and am going to end up with two 22 creed bolt gun builds, and a 22 creed upper for my AR10 lower. I'll have a 7, 7.7 and 8 twist, all between 16" and 18"
Looking at the 77 TMK, 85.5 Berger and 88 ELDM for the bolt guns, and I have a large stash of old 73 gr AMAX for the AR upper.
Got a Thunderbeast Ultra 5 and a Polonium K for suppressor options.
With all of the reported medium and big game successes with 224, I'll be taking one of the bolt guns for whitetail as well next year.
Thanks for all the input guys!
