is parallax a issue for a .22

If you are happy making your rifle shoot worse by using the wrong scope, well, that's okay by me. I'm trying to shoot better, not worse.

The math is fairly straightforward.

I was planning on shooting targets at 200-250 yards with my cz 452 in .22LR.

Parallax will be the least of your issues.

I regularly shoot small bore prone. A 5 mph wind change is enough to move a bullet from the center into the nine ring. That is why small bore shooters use wind gages, because no one can see a 5 mph wind change in the mirage.

Also, the elevation necessary to go from 100 yards to 200 yards is equal to the elevation it takes to go from 600 yards to 1000 yards with a 308. Around 24 MOA.

You will probably run out of elevation before you get there.
 
Folks, one cannot adjust parallax; they can only correct for it. And when the shooter's aiming eye's on the optical center of the scope as it looks through it, there's no parallax regardless of where the objective (front) lens is focused at.

I think it's stupid and irresponsible for rifle scope companies to call range focusing adjustment "parallax focus" or words to that effect.

A more likely possibility would be that the scope manufacturers actually understand parallax and you don't. :cool:
 
Parallax is not as much an issue for a quality scope as it is for your eye lense protection (or possible astigmatism). I have 63 year old eyes. I have an astigmatism that forces me to close my left non-dominant eye. I shoot a Marlin 60 with a Nikon Prostaff 2x9x40 scope and at 50 yards, punched out my bull's eye with calibrated adjustments to the rectical. I wear extended cheap reading glasses. If I keep my head after following the distance and angle to the rear scope for full view, there are no problems. If I tilt my head at an upper angle to view the scope at the top of my reading lense, I get a parallax view. If I raise my chin to look directly into the scope, I do not have the problem. Be careful when adding eye protective glasses with your chin down, and missing the full field the scope offers.

Parallax is a scope issue, not a .22 issue. All scopes have a specific range where the parallax is zero.

Take a scope that has zero parallax at 100 yards. Your eye is the gun's rear sight and the crosshairs are the gun's front sight. Optically, those crosshairs are 100 yards in front of your gun. When you shoot at something 500 yards away, moving your eye does the same thing as moving the rear sight of a gun with open sights. Moving your eye left moves the point of impact left.

When your target is 50 yards away, the "front sight" is 50 yards beyond the target and moving your eye left moves the point of impact right.

When your target is 100 yards away, the cross hairs are at the same distance as the target and moving your eye has no effect on the point of impact.

Many .22 specific scopes have zero parallax at 50-60 yards, reflecting the practical hunting range of a .22.
 
I have to agree with Slamfire.

Attempting to shoot 22LR at 250yrds... parallax will be the least of your worries.

Groups? You mean patterns measured in feet.

Better get the broad side of a barn for a target. You'll need it.
