you need to walkback tune. your arrows should hit the same left and right no matter how far...also work on form and grip. errors are magnified at longer ranges...not following through is a big problem...but it could simply be the tune...shouldnt have to move pins left or right...move the whole sight for that.
good luck...
This is very good advice.
It should also help your broadhead flight.
I would think you are only 1/32" or so from being dialed in.
It is worth a try.
You might end up being able to keep your existing sight.
