Just relating to the way things have worked for me these past six decades to my sight pins now has me asking: If I have set my pins at distances ranging from 10 to 60 yards, would the odds be better that my Ghost Buck will appear at a range of…oh say…35 yards? Would I be better served with pins set at the standard 10 yard intervals only beginning at 15 yards? The more I ponder this question, the more able I am to convince myself Mr. Bucky Buck will show up at 43 yards, or 37 yards or any number other than a yardage ending in zero. What do the gurus say?
I am not a guru but I practice aiming with the space between pins but, in reality, my max distance is approximately 25 yds so, I have a 20 yd pin and use it for everything. If the deer were at something like 27 then I would use the space between 20 and 30 but, like I said, I practice aiming with the space. I guess you could also call it bracketing my aim point with the points. Either way, that's what I do. I do practice out to 50 yds and use the other pins/spaces then.
So what happens if you sight your bow in at 25 and 35 and one comes out at 30? Do what Bruce suggested: learn to "gap" your pins... imagine four pins between your pre-set distances, and count down to the imaginary pin you need to put on your target.
thats where I would just keep it simple at even distances and practice, most pins sighted at 10 should come close to your 15 and even 20 yard targets as well. After that I just practice at all distances, use a range finder when practicing to see how accurate you are at shooting both even and odd distances. I'm confidant at any distance up to 60 yards after an animal if the conditions are right.
