Broadheads, Tuning For Accuracy:
 When switching from practice target points to broadheads on your arrows there is not much you can do with the broadhead to increase accuracy, the below items may or may not help. If these two things don't help then you must retune your bow with broadheads installed, or switch to larger fletching on the arrow shaft.
Note: Also See Bow Tuning & Crossbow Accuracy.

Making The Adjustments:
 1. Aligning broadhead blades with the arrow fletching. There are several companies that make aluminum, steel, nylon and rubber washers or spacers that will allow you to align the fletching with a good three blade broadhead. These will also aid in setting your (F.O.C.) correctly by fine tuning your weight.
 When looking down the arrow shaft from the nock end your three blade broadhead and fletching should look like the below diagram.

 2. The wobble test as it is known through out the world of archery is spinning the arrow in v-blocks to see if the broadhead is in true alignment with the arrow shaft and then visually make a judgement by eye only, whether it is concentric or not, to the best of my machining knowledge the human eye can not discern the difference of a few thousandths of an inch in measuring what is known as run-out.

 It is my belief that this is where most accuracy issues arise with bowhunters in tuning their broadheads.

 The tool to the left is the RCBS Case Master gauging tool used in ammunition reloading, it is a very useful tool for tuning arrows as well.

 By placing the arrow in the v-blocks you simply lower the run-out gauge down to make contact with broadhead ferrule where it is attached to the arrow, spin the arrow and observe the run out gauge for the run-out and make adjustments accordingly by loosening and retightening the broadhead until it is in perfect alignment with the arrow shaft.
