You can not shim a pin tumbler lock!!!
If you mean you are shimming to rekey then thats differant and you are useing the wrong technique,
Reading your post sounds like you are attempting to shim a cylinder like you shim a padlock which cant be done,
If you are trying to rekey the lock then you have got the wrong method and need to click my www button to see a guide on how to do it properly, no twisting, bending or turning of the shim is done at all,
