Explain this to me?
This weekend I was shooting my broadheads to make sure they were flying like my field points. I had already paper tuned and was shooting bullet holes with my field points. I shot some new three blade (100grain) muzzies at the target and saw them shoot way low and to the right. I shot several arrows and saw this pattern with all of the arrows, yet the grouping was not anything to be pleased about. Before I started adjusting things on my bow I tried a four blade muzzy 100grain head on a different arrow. I shot it and Bulls-eye, I shot four blades on the other arrows and saw the same thing. For a reason I can't explain the four blade shoots like my field points, but the three blade shoots awful. What is going on to cause this?
