None of my 7 TX's will group well with the Express pellet. My guns range from 12 to 14 ft.bs and the Exacts in 8.44 easily half the group size of the Express. Tomorrow I plan to try them once again in a gun that hasn't been out in 5 years. I can't remember if I actually tried them in this gun. I really want them to work, but they seem to have more frequent fliers.
