But depends on your setup.
What you need to do is check the tune of the bow/arrow combo. Yes, it makes a difference. Many different methods, but I usually make sure my broadheads hit with my field points.
Shooting a too stiff spined arrow will only rob you accuracy.
See thats how much of a rookie I am at shooting a bow, I literally bought my bow used off ebay and just bought arrows and have been shooting it. Sad to say I don't know much at all about tuning a bow and not real sure where I would go around here to get advice other than MAYBE cabelas, depending on who it working.
Big Country can you point me in the right direction?
