Wow good eye and memory Kimberman- that is the exact same scope. It has been used to kill a bunch of deer and some coyotes. In fact I like it so much I have 2 more on other rifles- perfect size for a hunting rifle, good optics, and inexpensive. The cartridge is the 6.5DTI from Dtech. It is based on the 6.8spc necked down a tad with a 30* shoulder. I like the 6.5 bore a lot having used a M77 .260 since 1999. The Grendel would be the most practical way to get there in an AR; ballistics are the same except the DTI version doesn't handle heavy bullets as well as they take more powder space. Or the standard 6.8spc would do the same thing. But I wanted something a bit different and Mike built the first 6.5DTI ever made for me. I think there is another one in the field now.
