Oh, and it can also stabilize the 75 grainers, just not as accurate as the 69's (75gr. TAP avg. .80 MOA). Haven't tried 77's yet, I know they won't shoot well...
But, my rifle shoots 55's about the same as it does 75's, and prefers 68, 69, and 70 gr. rounds the best. (BTW, all groups listed are average of three 5 shot groups at 100 yards with rifle locked in a rest and a high powered optic).
Have fun with that! Sure is a looker - I almost bought one, but prefered the mid-length free floated MRF on the T model.
