I've gotten good results with the 6's and my IC and Stardot (180-200) with one shot going in the 220's. The IC did consistently beat the Stardot with all loads, but the Hevi 7's. I was getting consistent 270's with the Stardot and 7's. I have since switched to the straight 7's 2 7/16 Nitro's with this load I get about the same numbers in the 10, but more in the 15 and higher velocity. The IC did beat the Stardot with the Nitro's.
