i agree with all that suggest you buy a 3-D type target it is well worth the money . Better to have it to pratice and know you can make the shot, than go into the woods and hope you can make the shot . As far as the broad head yes they will dull, i use the Muzzy they have practice blades you can buy , or what i do is i use the past season's blades as my practice blades. I shoot broadheads year round very seldon will i screw in a field point . good luck !
