Just how much does the parallax setting matter on a squirrel rifle's scope?

For those not as familiar with "parallax" (regarding a rifle scope), it is how much your crosshairs move OFF target when you fail to position your eye perfectly straight thru the scope tube.

Most rifle scopes (with non-adjustable parallax) are factory preset to be "parallax-free" at 100 yards. This means at 100 yards, even peering into the scope tube at an angle, your crosshairs will not move off target at 100 yards. But they sure will at 25 yards! Enough to miss a squirrel's head! Try it for yourself by moving your head slightly left and right as you peer thru a 100-yd-parallax-free scope at a target about 25 yards away.

Because of this "parallax" issue, most "target" scopes come with an adjustable parallax (often referred to as "adjustable objective"). And while most fixed-parallax scopes are factory preset at 100 yards, most "specialty" marketed scopes are not. Most "shotgun" scopes are set to be free of parallax at either 50 or 75 yards. Leupold's "turkey" shotgun scope is parallax-free at 40 yards. Nikon's Bolt "crossbow" scope is parallax free at 20 yards.

Another simple everyday example of parallax can be seen in the dashboard of motor vehicles that use a needle-style speedometer gauge. When viewed from directly in front, the speed may show exactly 60; but when viewed from the passenger seat the needle may appear to show a slightly different speed, due to the angle of viewing.

One reason I'm asking "how much" does it matter, practically speaking, is because I'm thinking of mounting a 2-7 x 35mm Burris Fullfield II on a new dedicated "squirrel" rifle. The usual targets will be squirrel heads at an average range of probably 30 yards, and seldom would a shot over 50 yards be an option. A Burris scope can be sent back to the factory to have the parallax reset to a different yardage (without cost other than shipping). This particular scope came preset at 100 yards, while I'm thinking about having it changed to 50 yards, or maybe even 40.

Thoughts?

I use a 100 yard paralax scope and have not had any issues with it.

I realize this isn't a huge issue, but just wondering what some of you expert squirrel hunters who are also experts with your .22's thought. Seems if most of your shots are under 50 yards, it would make more sense to have the parallax set at say 50 yards instead of 100.

not sure the effect. my current squirrel scope is parallax free at 50 yards. but more importantly to me, it has extra fine crosshairs which lend themself for precise aiming on very small targets

When I purchase my dedicated .22, I'll most likely get this scope as it has a 60 yard parallax setting, plus I know RB will be happy that I am purchasing my first Leupold.

Here is another good scope with a 50 yard setting. Field of view, which could be a big help in acquiring your target expeditiously, is awesome when compared to others in this price range. http://www.opticsplanet.com/vortex-diamondback-2-7x35-rimfire-riflescope-v-plex-reticle.html

Wes,

Here is a thread I found over on 24hrcampfire discussing this exact issue. http://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/4817218/1

that is a nice scope, perfect for squirrel hunting. It took me a long time to convince him to try a Leupold, but once he did that is all he buys now!

AO's are not practical for most hunting, especially squirrel hunting.

Here's what I already have, which is a slightly larger 2-7 than your Leupold. Since Burris will re-set the parallax to whatever, I'm just wondering if should make it 40 yards, since most shots will be under that.

Thanks for all the info! \:\)

My opinion is to sight it in and then give it a chance a few times in the field to see how it performs in your hands. If at that point I was still undecided and still possibly wanting to change it, I would more seriously consider the idea of shipping it back to get said adjustments. I am hearing a few guys (some on here and some local guys) say they have never messed with the parallax, and these guys kill beaucoups of squirrels with a .22 most every year. As previously stated, I think I would at least have to try it out 2-3 times in the field before I made my final decision. My .02 and best of luck with your final decision Wes.

I ran into this problem sevral years back, a wounded squirrel was only a few yards away & I missed sevral times & I know the scope was on the money.

I'm look'n for a new scope now & cant make my mind up as to which one, found a Nikon EFR with fine reticle & AO, but I aint a big fan on a AO, nearly more trouble than ther worth for my part.

likely because your scope is above the bore and at close range, this can make you miss low. I don't think it had anything to do with parallax.

Very well could be, need to experiment to see just how it does shoot at close range, sounds like a good project for the weekend.

Mount your head on the stock the same way every time and it would seem to me that you could eliminate most of the problem.

This Burris Mini 6x has an adjustable AO-I think it is a 'rimfire' scope. I'm not sure how much it helps but I run it set on 25yds unless I shooting at something much closer or farther. It seems to affect the focus more than anything but undoubtedly helps reduce parallax error. PH


Can't get the pic to come up. There it is.

I've been look'n at scopes for a .22 all weekend, dig'n around on forums & reviews, it all kind of runs together after a while.

Nice look'n critter gitter ya have the PH, what kind of goodies ya have in that little monster ???

Have a 10-22 thats "a work in progress" myself.

FoxFire, it has a Volquartsen barrel and a Jewell trigger. The Weaver 2-7 rimfire scope is pretty good and I think Leupold has a similar one. Dont think Burris makes this scope anymore. PH

This one comes with a 50 yard setting.

PH: So far the only mod I have is a Swamp Fox trigger group, think'n about have'n my factory barrel accurized & some bolt work done later on, for what Ive read it makes a big improvement but at this point I dont know the cost involved VS a barrel upgrade.

WC: nice st up ya have, left handed are ya ?? I looked at a Nikon 3x9x40 EFR the other day, loved the fine recticle but not so much the AO, Question...A 50 yards setting ?? think'n thats the first one I've seen, that model still in production ??

Yep, brand new I ordered it this year.

Go here and look at Nikons Spot On, it's free. You can put in any bullet and it will tell where it will hit and which line in the recticle will hit where. Go ahead and resiger, it's free. You will also understand the EFR better.

I use a Weaver RV7 2-7 Rimfire scope with paralax set at 50 yards on a CZ 452 American,,zeroed at 18 yards all you have to do is put the crosshair on its head and shoot,,if shooting straight up I hold a little over an inch to the high side of the scope,
