I have been practicing for a couple of months with field tips and am shooting pretty good. However, with our opener next weekend, I decided it was time to shoot the broadhead to make sure it is consistent, which I expected to be the case. To my surprise, the arrow is drifting to the right. Not a lot, but it is noticeable. I am shooting Beman 340's with three blade muzzy's.

Any thoughts on what might cause this? Have others experience similar differences or is something out of sync on my bow?

Thanks for the helpl
