Danny, It sounds like you've got a tuning problem, meaning that the arrow is not leaving the bow properly.
The guide will help you correct it, or at least to understand it if you choose to have someone else help you.

Puting fins on the front end of an arrow (like a fixed-blade broadhead) will amplify any error that exists in your arrow's flight. When everything is set just right, broadheads and field points will hit the same point at any range, barring a crosswind that will affect BH's more.

When you think you have it paper-tuned or bare-shaft tuned pretty well, try broadheads again and see how close you are.
Then make your final adjustments, and verify your point of impact at several distances all the way out to your max shooting distance. If deer season comes and you're still having minor problems, you can just shorten your range to a distance where things are working well and your groups are still relatively small.

Kudos to you for not being one of those guys who is trying to get together a new setup the week before deer season opens.

Good luck.
