very unusual for Me but this will be My second post today. I shoot a whisker and had problems.I got some info by evesdropping here and found My centershot off by half a arrow I fixed that by using a method I also learned here using a bow square and checking my nock by laying my square against the riser horizontaly then flipping it end for end and checking the arrow forward of th riser I hope the guy can post that again He had picsto show You but anyway once My rest was right I have had no more problems again like so many here say a properly tuned bow is the ticket to success...
