Well hummmm....ur hooking it right around where the scope is mounted putting alot of stress right there, not good for the mounting plate, and if that slips off from there it's going to hit the scope maybe enough to throw the scope settings off ......even worse it could rip the whole works off the mounting plate. Not saying it will do that , but oh my if it did. Yes the rope should go on the butt plate , really to be safe. The Excaliburs have that notch that the string can travel on....but the Horton , nope.....I wouldn't chance it.
