I am an avid deer hunter and have been for many years,but in order to lengthen my hunting season i took up x-bow hunting.I bought the Horton Explorer HD 150 with the 3-red dot scope.First time i had it out it was shooting pretty good.I think.Was putting all 3 arrows in a 3 inch circle at 30yds and all 3 arrows in a 4 or 5 inch circle t 40yds..I took it out today and it wasn't shooting so hot.Could it be because i am not holding my face in the same spot on the stock every time?Do i need to put line my eye up the same way every time with the scope,like you have to have a refrence point when you draw back a compound bow?Another question,Could the arrows be causing it?There seems to be nothing wrong with them.They have the feather fletching.I did notice that the quiver mount was loose,i mean real loose.Could that been causing the accuracy problems?I just want to be as accurate as possible with this bow,because im leery of bow hunting anyway(don't want to wound a deer and not find it).When you sight your crossbow scope in do you shoot off of a bench or off hand?When adjusting the scope is it the same as a rifle scope(if it shoots low give it a few clicks up)?Sorry for such a long post,just looking for some advice.Any other suggestions would be appricated.Note i do not know much about crossbows.
