Parallax requirements for airgunnig

If I understand correctly adjusting for parallax serves two purposes:



(1) To get the image sharp. 

➔ I can let my eyes adjust somehow for it.



(2) To reduce/ eliminate the offset of the reticle/ crosshairs in the scope image when the shooter moves his/her eye off the center of the scope. 

This is critical, as keeping the eye perfectly centered is extremely difficult — and offset crosshairs result in an offset POI....

Amen to that, I say 10 would be ideal but 15 is doable. My Vortex diamondback tac is at 20 with really sucks for backyard application.

IMO 25 yards is enough. I would rather go with a scope that is awesome and has a low of 30 meters or so than one I like that has 10. I am more interested in clear image than parallax. which sometimes go together. At 30 yards low parallax the error at 10 would be so small , would not matter unless you was shooting for gold medal or something, IMO. 

Funny thing is for probably 30 years of my hunting squirrels and shooting targets, I used fixed parallax of 100 yards and killed just as many squirrels then as now.

IMO if you'll be doing normal short range plinking that tends to happen often with me you'll want a 10Y or 10M close focus. I have a Burris 1-8x24 XTR2 on my AR, which has fixed parallax at 100Y or so, and on 8x up close the image looks weird - out of focus, and there's a ton of parallax error. As I dial down magnification the image becomes normal looking.

Yes as a kid I killed piles of critters with fixed 4x and 3-9's with AG's and 22rf's but why with the options we have these days would I concede by going backwards??? Also most of those critters were from 25Y and out.

For hunting I wouldn't want most FFP scopes if my intent was to dial the mag down to 8-12x. these are better suited for 12x and up so the reticle appears larger and is easier to see.

How about March's 2.5-25x42 https://marchscopes.com/scopes/d4v24iml/ this scope meets all requirements except you'll need to stretch your finances a bit. 

Seems that in most cases air guns are short range small target shooters. Close parallax ability seems to be a major advantage for such. If one never shoots closer than 100 yards then I guess it can be ignored. If one shoots at 15 yards with a 25 yard minimum parallax there would probably be some error effect. Comes down to ones usage of the scope and accuracy expectations, I guess.

For $2550* you get a great scope, a sense of pride of ownership, and a divorce.

I think it's a bargain. Three things for the price of one.

PS: Sorry for my sarcasm — I just couldn't help it. I'd love to have this scope!!

(But I love my wife more.)

I had a March 2.5-25×42. It was good. But kind of touchy with eyebox. The only scope I regret getting rid of, was a march 5-32X52. Wonderful, like a dummy sold it & bought the little brother.

Ha, good joke Jungleshooter!

Nut, I had the March 3-24x42 FFP, I noticed the same thing bbbbuuutttt the eyebox wasn't bad when dialing the magnification down to mid way. With the correct cheek weld, like I had on the rifle it was mounted on, it was plenty workable I thought. That rifle which I used for NRL22 was already too light for the sport anyway so I quickly found out a heavier scope worked better for my application.

DVOR great sale on Burris FYI. Yo!
