Parallax shooting problems can be totally eliminated with ScopeGhost. It is a small decal that applies to the outside of your scopes eyepiece thus providing a second aimpoint. You can find one on ebay or at http://www.scopeghost.com

Got any data to back that claim up?

We field tested it on several different scoped rifles (all .308's) and had better groups with it on versus with it off. Shooting usually improved from 1-2 MOA to as low as .3MOA. Not all rifles are capable of that accuracy, but every one performed better with the scopeghost. I even tried it with my 10 year old son who is fairly new to shooting and he hit 3 out of 3 5" balloons at 300 yards with the parallax adjustment set on infinity. It forces the shooter to align the eye exactly down the center of the scope every time. If your looking for scientific data, we don't have that yet. This is a new product and we're trying to get the word out. The concept is so foreign, so simple, that people are having trouble accepting it.
I'll send one to anyone who wants one for $5 (to cover shipping and packaging). Just go to my web site and reference this site.

I sent you an e-mail on this as i have a match this weekend and would like to test it for the match to see if it really does what you say.

Thanks to all that have replied to my $5 challenge. I am now offering free samples to the next 25 people who send me their mailing address via my web site. Those that have already replied will not be charged either. All I ask is that you report your favorable results publicly so that the word can be spread. If you have any problems with it I ask that you e-mail me privately so I can address the issue. I also ask that you only reply if you are a serious shooter. Thank You.

Heck try it for free, cannot beat that price! besides it looks like if it doesnt work there is no real damage to your scope!

Let me add a demonstration to the parallax problem in scopes. Hold your finger out in front of your face and line it up with an object. Now move your head left and right. That is parallax. Now line up two fingers at the same object, like iron sights, and move your head the same as before. Your fingers are still pointing at the object but you can obviously see that your eye is in the wrong place. A scope only has one aim point and your eye is the other. If it's not in the same spot every time, you're going to be off.

Well, not exactly. Parallax, as used in the telescopic sight world, is when the point where focal plane of the object and the focal plane of the reticle are supposed to meet but don't. This causes an apparent movement of one vs the other when the shooters eye moves - the "last" focal plane of the system. There is a lengthy dissertaion about parallax from a guy who was an engineer for Leupold and now does testing of scope systems somewhere on this site. If you can't find it I have a copy I converter into MS Word format. Invaluable reading.

As far as relatively precise shooting goes, once you get to 12X or higher nearly all scopes have a "focus/parallax" adjustment - either on the objective end or internally. I've never owned one that I thought was perfect. With the objective end type my only complaint is that the reading etched into the ring doesn't match the distance where the focus is sharp and there is no parallax. With the side knob type, due to "manufacturing tolerance" or slop as it's known, it's necessary to turn to infinity then to the correct distance. If you turn it back, the image will either be out of focus or significant parallax will be evident.

I would venture to say that pretty much all long range shooters make the parallax adjustment without regard to what the numbers say and in a lot of cases, sacrifice image clarity in an effort to eliminate parallax. Some of them may not completely understand the physics involved but that's really not necessary.

At magnifications such as 3.5-10 or 3-9 it's a different world. With a few exception, focus is fixed, parallax is usually set at 125 YDS or so. Then something that forces the shooter to look through the center of the objective could be quite valuable.

There is another potential benefit you might have overlooked. Some of us, with aging eyes, can see far more clearly through a small aperture since the image passes through the center of the iris. When I manage to go to the grocery store without my reading glasses, I can make a small circle with my thumb and forefinger and read things like prices, etc.
