I don't know how to correct yer problem,i have an Excal. I have a rifle scope on mine and i just adjusted it like it was one. I shoot dead center at 25 yds. Up closer all is high and ferther is all drop lower. Can't remember, i just moved elev. and windage the opposite way my arrows hit. If it was shooting high and right i moved it left and down until it got to dot at 25 yds.[]
