Ossage,
Haven't seen the article you're talking about.
In the past I practiced out to 120 yards with my Accu-Riser I.
I easily got the yardage needed out of my HTM Long Range Dominator sight with more to spare.
It is lots of fun and I can usually get all 6 arrows, I practiced with, in the target bag at that distance.
If I miss, the arrow is slowing and dropping down so much at that distance that I don't have to worry about it slipping beneith the grass and losing it.

I don't shoot at game beyond 30 yards because of the energy loss and slower speeds.
Sag.
