RE: sighting in
 

To find out if anything moved, take careful measurements. ATA, brace height, peep to nock and nock to axel. Be precise. Next time you notice it shooting differently, remeasure. If there is no change in the measurements, you'll know it's you, not the bow.

RE: sighting in
 

my peep is a tube type

i will take some measurements and look close to see if there is any movement of the peep and let yor know.

thanks for the help

Check your rest also. Is it tight?
