So the next time you get stopped for speeding try telling the LEO about parallax.

It's easy to see in a riflescope. Set your scope in a solid rest, get the crosshairs centered on a target, lock it down so it can't move and then move your eye back and forth, left to right. If the crosshair moves off target, you have parallax. You can neutralize the effect by carefully placing your eye behind the scope so that the crosshairs are perfectly centered in the scope.

For most types of shooting, it is not a big deal, but when the targets start to get tiny or when wining is the difference in hundredths of an inch, you need to deal with it. Parallax is more pronounced at short ranges, so you'll often see adjustable objective scopes (scopes with a focusing mechanism on the front of the scope to perfectly focus the scope for your given range and hence eliminate parallax) on air rifle scopes. You'll also see AO (adjustable objective) and SF (side focus) scopes used in varmint hunting and target shooting.

For other types of shooting, I don't care for them or think they are necessary, but, then, I am a big believer in keeping things simple, especially for hunting. The less you have to fuss with when hunting, the better. That's me, though. Some folks like to carry a sporting goods store and every gadget made with them when they go hunting. Each to their own.

north country gal ............ I'm proud of you and I agree with your answer 100% to Sightngrl There not many shooters or hunters that have a idea how parallax works and the effect it has on short and long range shots .

With semi-autos it is s easy to just put your eye up to the scope and shoot away without any problem. But then the next time you shoot you may have a wondering zero. I have practiced taking my head away and putting it back to make sure I get the same cheek weld.

Remember a couple months ago when I was having the problem of everything shooting high and to the left? I was using peep sights and my guess is I was using a different cheek weld that day. I didn't re-adjust them and they shoot fine now.

Thanks, TX. Coming from you, that means a lot.

303, it's always the little things, isn't it? Glad you got those peeps shooting the way you want. Yes, bless our peeps!
