I'm almost embarrased to ask this question because I should have had my act together a little better. First of all this is the first year I've hunted with a scope. I have a 3x9 and sighted it in on the highest setting. I'm going to be hunting in some thick stuff and want to dial it down a bit. Will dialing it down throw off the accuracy? I know I should have thought of that when I was sighting it in but sighting in was a fiasco in itself so I didn't even think of it. Any help is appreciated.
