Can't find it here either. Love it in 22-250, 308s and 35 Whelen.
Haven't experimented with much others. I've compared it to R15 in the whelen though. Side by side accuracy is really similar. Till it gets above 45 degrees or so and the R15 loads open up. I've shot varget from the teens to the 90s from the 22-250 and don't see a change.
