I have heard alot of you guys say that when you sight in your bow with your field points that your broadheads hit in just about the same area as your field points did. Well I'm having a little problem that I need some advice on. I sighted in my bow with field points (Tomkat 26" DL left handed, 70#, 400 gr arrow this is with the 100 gr field point, broadheads are muzzy 100gr 3 blade) & got it dead on @ 20, 30 & 40yards (all shots were within a 3 inch circle. Then when I switched to my broadheads my shots were off. Mainly 3-5 inches to the left and right. Could this be shooter error & myself pulling off or should I be looking for a problem somewhere else, or is this normal? I used same arrows that I shot my field points with & the broadheads were new without any obvious flaws I could see. Thanks for any input.
