RE: ? for excal guys
Those heads are a very good head and are generally very accurate. I found that with different bows that the point of impact could vary from field points, but, not very much and still be very accurate. Still do not shoot more then one arrow per target or you aqre risking dammage to your arrows (that accurate.
I switched from them to the spitfire for the extra cutting surface and still have the pin point accuracy (exactly the same as target blades). I would still recomend the head with the right stuff package for a biginner as they are a great head and are very dependable. Only thing is that you will need to use one head to practice just to ZERO IN your scope (minor adjustment).
Good luck and enjoy.
