All this 16, 17, 18 stuff. :D
I try to practice without knowing or thinking yardage and change it up. It was a nice confidence builder to shoot from 15 foot elevation on about 10 yard shots this evening. I shot a buck at about 20 last year, but guessed it was a little less. Even though I got him, I was fortunate because he turned at the shot, so something to chew on.
When I shoot at most anything I wait for the green light to go off, have faith that I can hit it and don't think much about yardage. For people that are better shots and more experienced than me, it seems like 25-30 is doable under the right circumstances.
