6SLR is one I've often thought about for both PRS and f class.
Yup,.. THAT, "Sweet Heart" and the 6 XC ARE,.. proven "Winners", Especially at,.. 800- to 1,000 yards,..
IF,.. the winds NOT Blowing,.. too Hard !
Love my, 6 XC with, the 1-7.5 Twist ! ( If, wanting to shoot, the 115's go, 1-7 TW. )
Mine Shoot's Everything from, 80 grain to 110 grainers into, "BugHoles",.. of course, with some Bugs, being, slightly bigger than,.. other Bugs.
Me personally, I'd AVOID the Gay Tiger, as not having quite, the "Horse Power" of, these Two.
Unless, you like,.. the "Rainbow", Trajectory.
