Bulletproof Bow Tuning From Petersen's Bowhunting Magazine
Properly tuning your bow could spell the difference between shooting your next big buck and shooting at it.
By Dave Dolbee

Bow tuning is about as real as Snow White is to most archers. They think that it is either a fantasy to tune their own bow, or they hope the fairy tale will come true and Prince Charming will ride up and do it for them. What they usually end up with is someone from the Flintstones whose knowledge dates back to the Stone Age, and they are worse off than when they started: Their bow still isn't tuned, and they are more confused than ever.

Here are 12 simple steps to bulletproof bow tuning that any archer can do themselves with a few simple tools.
I should first note that you should not attempt to tune a new bow straight out of the box. The strings and cables will stretch as you start shooting, and any tuning that you do will be out the window 10 to 15 arrows later. The same is true of a bow that has just had a new string or cable put on. Shoot the bow, break it in and, most important, make sure that you are familiar with the bow and how it feels from the beginning of the draw all the way through the recoil after the shot before you try to do any serious tuning.
