I use the bare shaft method from time to time just so that I know my bow is in tune. I shoot a string loop and a release. Just make sure that you're not shooting more than 10 yards and you have a good back stop for safety reasons. I usually shoot the bare shaft first and then shoot a fletched arrow beside it so I can make the comparison. Also you want to pick a day when the wind is calm and you'll want to shoot 3 or 4 times before you make any adjustments if needed. Happy Huntin..
