Others Working with parallax error

[Nordic Norm]

Hi folks, Fixed objective scopes are set for 50yds (rimfire). Shooting short range, 5yds there is considerable parallax error. This is easily corrected by this simple method. Mount the scope forward unril a black ring is just visible around the ocular as you sight it. Moving the eye slightly farther away increases the black ring, closer the ring disappears. Use that dark ring to keep the eye centered while aiming. Keep the ring consistent around the outside of the sight picture, like a big ghost ring. This will eliminate parallax error. This is quicker than focusing an AO scope when shooting at varying close ranges.

Ya, I was just talking up eye relief and scope shadowing. Like me I use cheap package scope one piece mounts and they really don't allow (for me) that fine tuning on that along the rail or tube. I can go close but no cigar ..

Like you say a non-AO scope it makes more difference if you get it right to your cheek weld and eye.

The key here is, that exceeding eye relief shadow, when centered evenly around the view, puts ones eye in the same position every time. It is a reference to being consistent as per crosshairs on target.

Well .. I was to figure you eliminate it

 

[Nordic Norm]

Yes, that is it after some practice and familiarity with a rifle/scope combination. It is easier for me to have that field visible to learn the focul center into reflex. I believe you are pointing at that when you mention cheek weld. Once the hold is natural, then the outer distortion isn't entirely necessary. I prefer to keep it accessible in case of shooting from an odd position, or when shooting left handed, or one handed.

There is a more subtle distortion ring available when crowding a scope. A blur ring. A little harder to see in low light. It's at ranges closer than set parallax that are the most affected. A 50yd set parallax at 5 yds can vary a shot 3/4 of an inch if one always sights in the center of eye relief range without regard to sighting in the center of the optics.

Ya, I know I really need a off set / set back mount for better comfort . I tend to need to lean in a yad with the mounts I use .. just been too cheap to order any .. I have a time getting them as best I can as is with mounts I got .

Anyway just thought funny I was discussing this kinda thing the other day and the next day +/- you made a thread ..

Great minds think alike

Now your overestimating me

I think a lot of average shooters doesn't spend the time required setting up a scope and cheek weld. They get something new and slap it on and make it work.
For my work I have done a lot of dry fire exercises with my pistol and rifle. It's not spoken much about on the AG forums, but its just important for us.
I have spent half a day in the past mounting a scope and adjusting a cheek riser to get the perfect cheek weld and scope location.
I say all this, because using the technique by the OP, you need to know your rifle and scope. It can be learned and be quick, but you have to put in the time.

I'd try this if it came in 11mm dove , but it seems Picatinny only.

Offset Adjustable Length Scope Mount - 30mm

Built to mount 30mm scopes to any standard Picatinny rail equipped rifle. The offset design provides an additional 2.00 inches of forward extension, allowing extra flexibility for optimum eye relief and shooting position. The ring length is adjustable in .25" increments at 5 different settings

Exactly why my favorite break barrel scope is the UTG 4X Hunter. It is designed for breakers with an optimized parallax of 35 yrds. Not 50 or 100 like standard rifle scopes and it can take magnum springers.
