This may come as a stupid question, but...... has anyone played around with mil-dot or ballistic reitcle rifle scopes on their long range crossbows? I'm wondering if a multi-reticle rifle scope caliberated for say 5.56 or .308, for instance, at distances of 100, 200, 300, etc. yards would be anywhere close to working with a crossbow like a TAC-15i for say 30, 40, 50, 60, 70 or 60, 70, 80, 90, 100 yards. I know the range calculations using a mil-dot won't translate of course. But I'm wondering more about how close the drop compensation would be between the two at their relative distances. Just playing with ideas here as I have a pile of rifle scopes in my collection. I'll enjoy playing but hate to waste time on something someone else may have already proved a fruitless pursuit. Thanks, Steve C.
