When at the range today I hit my forehead with my scope a couple of times. Would this potentially change the sights? I figured out why I was hitting I just know want to know if i should worry.

It might rattle your eyes, but it won' t change the sights.

Are you talking about recoil causing the scope to move back, and that causing you to hit your head? That is very possible if the scope rings aren' t tightened down properly. More than likely, you' ve changed the way you hold the firearm. What caliber is it? If it' s not a monster magnum, you shouldn' t be having that problem if you' re holding the rifle properly, and placing your head in the right position.

Try closing your eyes, mount the rifle like you would when taking a shot, then open your shooting eye. If you have to move your head forward or rearward to get a nice, clear, round image, you need to have it repositioned.

If, while at the range, you were shooting from a bench rest position, you may have creeped up on it too much. It' s very easy to do when hunched over the gun as most benches don' t really allow you to shoot from a more upright position.
