Query: Never buy broadheads that dont have practice blades

I have been using Muzzy broadheads for a long time. The fly straight, and get the job done as long as you do your part and put it in the right spot. Did they shoot the exact same as my feild points when I first put them on: NO, but after tuning my bow to them, all my field points and broadheads group together. Check out this site for instructions on tuning your bow to your broadheads: [...].The number 1 thing I like best about Muzzy Broadheads is the fact that they have practice blades. Practice blades will extend the life of your target by up to 10 times, they are much easier to pull out of the target, and you do not cut yourself while using them. Plus, if you feel the blades on your broadhead aren't sharp enough, you can put new blades on it.
