Ok so I went to my local hunting store and had the guy help me sight in my 20 yard pin, because our yard is only about 15 yd. I have a three pin sight and my first pin was my 10 then my middle my 20 and third 30. Well anyway I told him that the middle was the 20 and that it was shooting high. My top two pins our right on top of each other and there was no room to move it up.So he made my 10 pin my 20 and 10 pin. He said it would shoot low, but it's shooting about an inch to 2 inches high at 10. I don't know if I should leave it or just resight it like I had it before. Any ever use 1 pin for two different yardages. Thanks for any help!
