Ok I have used a Pin for years. Last year I put a regular Rifle Scope on it last year. Set it for 30 yards, if its 40 yards shoot a little High if its 20 yards shoot a little Low. Think I would be better with Crossbow Scope or leave it the way it is? And how about a Range Finder? usually shot Deer close and have let Deer 40 yards walk because just looking I thought they were too far. oneshot The Big Grin lets them get in biting distance.
