I have killed a number of animals with my 260 and 260AI using the 140 Sierra Game king SBT bullet. In 6.5 caliber that is a very good bullet- just not a good 1000 yard bullet as it gives up a lot to the wind and a lot of velocity. The ELD-X claims to be the Holy Grail- working at both high and low velocities. Again, I have an experience of once but it was a good one and the bullet did exit.
