The 100 gr TTSX in a .260 has produced very consist terminal results for me on small bodied does up to large bucks weighing 230# on the scales, as well as hogs which are more challenging for bullet performance. The 6.5 100 TTSX produces noticeably better penetration and larger wound channels than the 80 gr TTSX from a .243.

For .243, the heaviest Partition the rifle will shoot well is the way to go, but the 6.5 TTSX is noticeably more effective having used both. Recoil is very pleasant, but teach her to lean forward from the waist into the rifle to help control recoil.
