Mine is a 1-8 Broughton 5C.
With using the 115's you need a true 1-8, and with the new 117 DTAC's maybe a 7.5 twist.
The 117's are a poly-tipped bullet. Once I can get some I want to see if they will stabilize in my XP-100 handgun.
My MV is just a tad over 2700 fps but mine has a much shorter barrel than yours will.
