Ok, an old question I'm sure, but I want to ask before I go moving stuff I don't need to;

I'm getting three arrows to touch each other at 20-yards with field points, but my broadheads hit WAY to the left, like about 6-7". Everything's center-shot just like it should be. I turned the bow down about 5-pounds till the broadheads hit where I was aiming, but then the field-points hit 6" to the right.

Any suggestions?
