An update. I got the itch to try the 160 TTSX out. It has proven to be one of the most accurate loads on my Kimber Montana with AA2230/BR2s. They consistently chrono 3020-3040. Took them elk hunting this year, and while the resulting shot was a chest shot at only ~50yds at 10,600' elevation, it worked very nicely on the bull. Next up deer, but I have no issues sticking with this for elk in the future.
A few quick shots (at 50 yds...max for that indoor range) to ensure it's still sighted in.
Where he was standing when hit
Very good blood trail, total distance traveled 30 yards.
