Bow help
What do you guys think.
I have had my bow since 01 it is a Fred Bear code. I have no idea how many times i have shot it. I used to shoot league but know i just hunt with it. I cannot group with it like i used to be able to. The box it came in said it is a 70lb bow but i can only get 63lbs out of it. Also the vanes on the arrow hit the riser which they never used to do I have adjusted everything on the bow but cannot fix any of the problems. Would a new string help?
I took it to a pro shop because I thought the limbs might be warped but they said they were ok. Any suggestion would be helpful.
