60 is the max.

I practice it...and under the right circumstances I would shoot it. I have never taken the 60 yard shot on game, but if it came down to it...I would take it.

The farthest I have ever shot was 30 though, and I' m plenty confident from 60 to zero.

Most of my shots are 25 and under, with the once in a blue moon 30 yard shot.
