So, I am getting ready for archery season. I am going to do it this year gentlemen. I am going to harvest a really nice buck with the bow, and I am confident I have been practicing and grouping really well, but the difference in only 2 yards is about a 4 inch drop in my arrows. I am shooting a light weight youth bow and still only drawing the required 35 lbs with my chicken arms At 18 yards, I am pretty much dead center with all of my arrows right there and nice and tight, but when I move back to 20 yards, my arrows drop by 4 inches and I am not comfortable with that. So, do I set my pins at 15 and 20 yards, cause setting the pins at 18 and 20 seems a little silly to me. Any suggestions?
