SHOOTING 101 QUESTION

[group therapy]

THE LAST TIME I WAS AT THE RANGE, BREAKING IN A BARREL, I NOTICED THAT WHEN I LOOKED THROUGH THE SCOPE, THE CROSSHAIR DOT WOULD MOVE ON THE TARGET AS I MOVED MY HEAD. I DONT REMEMBER RUNNING INTO THIS BEFORE. I ADJUSTED THE SIDE FOCUS AND THE FOCUS ON THE END OF THE SCOPE (EYEPIECE) TO NO AVAIL. IT WAS 100 YARDS, SIGHTRON SIII 10-50 ON A 6BRAI IF ANY OF THAT MATTERS. AND THE TARGET WAS VERY CLEAR AND FOCUSED LOOKING THROUGH THE SCOPE. ANY ADVICE IS APPRECIATED. THANKS. BRYANT

with the Sightron scope the AO is kinda tight and it is very easy to go past where you need to be,,,,after focusing the eyepiece you should be able to adjust the paralax out on the side knob,,if not something is wrong,,

so this is a parallax problem, which is the side focus?

Certainly sounds like it is.

knob on the side is actually the paralax adjustment,,the focus is on the end closest to your eye,,,,,side focus is not really a good phrase ,,it should be side paralax adjustment,,

You continually move your head around while looking through the scope on target and adjusting the side parallax without letting your face touch the rifle. Continue doing this until you have a clear sight picture and the reticle remains solid regardless of your head position. Do not pay attention to any yardage markings on the side parallax adjustment as they can be misleading. Once it's set where you can move your head around and the reticle stays solid on the point of aim you're good to go.

You would not have experienced the parallax effect with other scopes if they did not exceed 12X magnification. Parallax only occurs on high magnification scopes

Thanks for the advice. I'm getting the picture now, no pun intended.

 

[Ledd Slinger]

This video does an excellent job of explaining the parallax adjustment procedure I am talking about.

thanks for the video!!problem solved.

My pleasure. You're welcome

Parallax can occur on any scope. It is simply more pronounced on higher power scopes.

Parallax will occur with any magnification scope- it just is not as apparent as on high magnification (to the average shooter). This is why Leupold, Burris, and old Weaver (el Paso era) marketed 6 power scopes specifically for Hunter Benchrest that had Parallax adjustment- this competition is capable of extreme accuracy that rivals the Varmint For Score (unlimited optics) discipline. Often a match has been contested where the Hunter Class rifle agged a higher score than 90% of the VFS competitors competing.

My apologies. Should have said "not easily noticeable" on low power scopes. Most modern variable optics under 12X have the parallax corrected so well there's no point in having any adjustment for it.

 

[mikeeg02]

Just to reiterate. With my two 10-50s, every time you change magnification, or change yardage, you need to adjust out the parallax. And as you've noticed, just because everything is in focus, does not mean the parallax is out. Sightron does well to have a wide area that the picture is in focus, but you need to keep going until the reticle stops moving. As I said, it is affected by changing magnification too. At least my two were. My comps don't seem to be affected by that.

Note that 100% parallax free is not achievable.

If this is true then why did Leupold make a 3 to 9x scope with adjustable objective?

Parrallax = the apparent movement of crosshairs. Don't go by the #s on the scope , they are for reference, generally . Everyone's eyes, are different. Eyeglasses, humidity, temp ,sun location , exact range etc all make parallax a change required many times throughout the day . At least for me , could be my eyes just getting tired .

 

[Ledd Slinger]

Because Leupold optics are junk.

No you cannot get a scope perfectly 100% parallax free. Kahles scopes come about as close as you can get to achieving perfect parallax adjustment. Lets not turn a simple subject of helping a new shooter with adjusting out parallax turn into a shit show of keyboard warriors trying to get their 2 cents in just to feel like they've made a point.

 

[hogpatrol]

If this is true then why did Leupold make a 3 to 9x scope with adjustable objective?

Most low power scopes have fixed parallax at 75 or 100 yards, hence anything closer can be blurry. For a demo, try shooting a 3x9 on 9x scope at twenty five yards.

25yds can be a challenge for a lot of scopes. It is even more fun if you need to shoot closer.
