Ive used Swords Accusite 3rd Plane for the last 10 13yrs and every sight l have (4) are all the same l called them and asked to get .29 fiber for my 20yd pin .19 fiber for 30 and 40yds and .10 fiber for 50yd pin and l cant ever see my self changing. I use to try and shoot 50yds with a .29 fiber and it always literally took up the whole deer. With a .10 fiber at 50yds l can really settle that pin where it needs to be.
