Thought I would bring this back up with an update. The 62 Grain TTSX ended up being the winner. Half a grain off of Barnes' max load of RL 15 gave me a 3/8" group at 100 yards. Right at 3500 FPS over my chronograph. Will be putting it to use on an antelope hunt in early October. And on a doe whitetail grocery getting trip in November.
