Lots of great info.I apprecaite all the input!!
Now I guess I have to shoot my crossbow through a chronagraph to know how fast it shoots????
No, as you suggested, it is better to sight in at 20 yards, then at 30 by turning the speed ring only, 40 with speed ring only and the 50 by speed ring only. The go back and reconfirm 10, 30, and 40. Don't worry about 10 too much. For me, 10 is about minute of deer accurate!
