If you are shooting a Sure-Loc sight and having problems using TAP getting the sight Tape to match your scale it has been found that your scale is likely off.  To verify this measure from 10 on the scale to 58 on the scale.  You will need a very accurate ruler and it should be exactly 2 inches.  If it is not you can download these scales and print the 24 TURN scale and replace your Sure-Loc scale with this one.  Now TAP's marks and your marks will be SPOT on!
