What factors can contribute to broad head inaccuracy? And what are the cures?

Most of the time, broadhead inaccuracy is caused by a bow that is out of tune.  When shooting field points, the arrow fletching can compensate for a poorly tuned bow and still allow the arrow to hit where you are aiming. Once you put broadheads on the fletchingss aren’t able to correct the poor arrow flight enough, which is why your broadhead-tipped arrows will not impact with your field-tipped arrows. This is most common with fixed-blade heads that act similar to fletching on the front of your arrow, and why you hear people say that mechanical heads fly more like field points.

There are a few different ways to tune your bow for good broadhead flight, and all of them work if you do them properly.  Personally, I like to paper tune my bow first.  That gets me pretty close to where I need to be and will solve most of the up/down issues with your rest and knocking point. Then I will go outside and do a walk-back tune, which takes care of your horizontal or side-to-side tuning issues. If you do both of those properly, your broadheads should fly good and impact with your field points.

Of course, there are other issues that could be at play here such as cam timing, rest timing, improper arrow spine, and others. But an out of tune bow is the most common cause of poor broadhead flight. ~ Justin
