But EVERYONE'S optics (Etoech, Aimpoint, Elcan, Acog, Millet) were off and had to be adjusted.
this is an interesting point. as i've said many times, any High Power shooter can tell you zeros change. but, that in my experience, applies equally to optics and irons. heck, i had to adjust the irons on my 22lr lever gun today which i haven't had to do in years, and they're fixed, soldered to the barrel!
