I shoot muzzy 125 grain fixed-blade broadheads and i get perfect flight at 20 yards with my 20 yard pin, but horrid flight at 10 yards with my 10 yard pin. Any suggestions on what i should do?

Don't use your 10 yard pen?

Sorry, could not resist. But, depends on which bow you are shooting and the speed your are getting with your arrow. Personally, I use one pen from 0-30 yards with my bow.

Your bow must be out of tune. Why do you have a 10 yard pin though? Unless you are shooting a very low poundage bow your 20 yard pin should be good for anything 20 yards or less.

I agree 100%, there really shouldn't be a need for a ten yard pen, at five yards I use my 40 yard pin. You know that an arrow actually drops the first few yards? I suggest to set your pins starting at 20 yards. Then at five yards (using the 20 yard pin) see where you arrow hits and walk backwards to see what the arrow is doing at shorter distances. I won lots of money taking it from guys at four or five yards. Most people never shoot that close and don't have a clue what the arrow does or how to shoot that close. You should know at all distances, you never know when you have to shoot a snake, sometimes they get real close.

This is me (wearing the boots) lol
