if you have enough arrows fletched up, shoot some with field points and some with broadheads and look at where your broadhead arrows hit in relation to your fieldpoint arrows. This works better for me than bareshafting. For right handed shooters, if your broadheads are hitting right of the fieldtip arrows, your shafts are too weak...either shorten the arrows a little at a time, go with a lighter point, or build out your sideplate...if they hit left, they are too stiff so you will need to add more weight up front. when everything is tuned, your broadheads will fly right with your fieldpoints at any distance. sometimes tuning can get frustrating.
