Morning and HAPPY HOLIDAYS to everyone on this awesome site....  I shoot a Horton Team Real Tree Ultra Lite.  Trying to sight in the bow for the first time.  I've run about 40 arrows through it so far..At 20 yards, dead on...30 and 40 yards, within a 3" circle...( I know that could be better )  at 50 yards though, I'm 3" high consistently.  The scope crosshairs i believe are set +/- 10 yards apart.  Other than that and the distance being off a bit ( I'll remeasure that)...any ideas on why I would be fairly on target from 20-40 and at 50 be 3" high?  Any advice would be appreciated.

Merry Christmas!!   Andy

Andy, I look at the situation a little differently.  What you are experiencing is the result of the crosshair or dot spacing of your sight/scope not matching the speed and trajectory of your crossbow.  For some reason, everyone expects their crossbow to shoot in precise 10 yard increments with the crosshairs of their scope, but it doesn't always happen that way, and is really no big deal if it doesn't.  You just need to know at what yardages your aimpoints DO yield a bullseye or killshot.  If your scope/crossbow is 3" high at 50 yards, move back a little until you are hitting bullseye, then measure the distance; it might be, say 55 yards that yields a bullseye.  That's really all you have to know.  Deer usually don't come into exact 10 yard ranges anyway.  If you have a rangefinder or if you use flourescent tape to mark your yardage where you hunt, putting tape up at the 55 yard [or whatever] point will let you know where that crosshair will get you a killshot.  
When I had my TRT UL, I had a Barska 3 dot/crosshair scope on it and I found that sighting in the first point at 30 yards also yielded a killshot at 20, and the other 2 aimpoints fell into line at 40 and 50.  You might try sighting in your first aimpoint at say 25 or 30 yards and the others might fall into line where they yield killshots at the other points as well. Experiment a little.

Hi Andy, heres a link to arrow trajectories that might add to Jacks explanation. Merry Christmas all!: http://www.excalibur...ow_ballistics

as I was reading this "highat..." post, the first tihing that came to miand was anold co-shooter,ok he was younf then. He(or someone)  had sighted his new .22at maybe 25 yards and was hitting the target farther down range, but could not understand why he missed everything in between!He asked for help
I asked him to draw a profile of the bullit in flight to target. he drew it a sraight line to both hits, I said he was young, then I aske him several questions so he corrected the trijectory, understood after he realized bullet crosse "line -of-sight twice! Omce going up to scope line and agin when coming back down, so of course he was high in between
