i just put my leoupold lr 8x25 scope on my wifes new blaser tec 2 that she got today. i am loaning her this scope untill i save enough to get her a night force. when i used it on my 338 hart i never changed powers. she has her cheek pc set for her face to rest on and when she goes from 8 up to 25 power she has to move about an inch closer to the scope. i never noticed this before. then her cheek pc is out of wack. has any one had this problem ??
