Field tips and broadheads not shooting the same?

[rem270]

I've never had this experience before but have heard of people having this problem. In my old xbow I was shooting the same fixed blade BH's and they shot the same as the field tip. Now in my new crossbow my field tips were dead on from the factory like wicked ridge said it would be but my BH's were shooting about 3 inches lower. Got the scope set with my BH's and didnt shoot my field tips again because it got dark on me.

Wonder why this would happen? Now its got me wanting to buy some BH's that have the practice broadhead with it. What would yall recommend? Rage, Shwackers, NAP?

And im shooting 100gr FT and 100gr BH.

Muzzy MX3, you can get practice blades with them. G5 Montecs are what I shot prior to them they also make a practice head. Both of these broad heads fly just like my field points. Years ago I shot Thunderheads but always had to adjust my sights when shooting them. I used to shoot mechanical heads too but got tired of bent blades after every deer so I went back to fixed blade

Spitfires, they will fly the same as your fieldpoints.
