what is the best way to sight in my crossbow.i have a horton hd175 and shooting mechanical broadheads.i currently have it sighted in but during the rush to do so (bow season was already underway) i have the dial set on 4or 5 and am able to hit the traget well.i would like to go back to zero or matbe one.if anyone has a prefrerred method that works well i'm all ears.thanks.

Yo Da-squirrel yer chain has been rung, plus several other fine Horton shooters!

You left out one tiny little detail, lol, what are you using for a sight? If it's ared dot, you will pretty well need to put the dial-a-rage where you want it, like 2 for 20 yds and start over. If you have a mutli-reticle scope, you may want to pin the thing in one place semi permanent as lot's of guys have had problems w/ rope cocker changing their range setting on that gizmo. I shot one of those bows a week or so ago, nice little bow, but would not shoot fixed blades anywhere near target arrows, mechs are the way to go, imho.
