Hi Folks,
I have a "200th year of American Liberty" 10-22. Deluxe model. I would like to top it off with a reasonable scope. The scope I was thinking about was the Nikon Prostaff Rimfire 4-12X40. It has a fixed parallax at 50 yards. I wouldn't mind shooting at 100-150 yards on occasion. What would be the problems I might have shooting at those distances with an nonadjustable parallax scope? On a bench rest, and keeping my eye centered, how much off center would the cross hairs be?
Yeah, I'm new at this.

Parallax error is not sot so much at lower magnification.

Got a 1-4 scope (100 yard parallax setting) on my Charger and I can do bugholes with it at 25 using CCI SV. Beyond the aforesaid distance, I would need more magnification for precision shooting.

You know, at 1 to 2x I have no problem aiming at objects from less than 10 meters.

Oh, I might try it again tomorrow coz I now have my fave ammo, the SK Pistol Match which is a fave of my KIDD and GM barrels---my Charger has a KIDD barrel too..

A nice recommendation, and works on airguns too :t

He might want a bit of mag higher than 9x though.

At 50, I have no problem at 9x, I actually set mine between 8 and 10x, I can still do very precise shots with it for as long as the reticle is thin.

Check out KYGUNCO, they have a silver Nikko Stirling AO with a stadia reticle on sale at $50.

Thank you for your insights. I'll have to check out your suggestions. However, I want to be educated on the practical implications of having a Non-adjustable parallax scope.
If I am shooting at 100 yards with a 12x magnification, and the parallax is zeroed at 75, how would that affect the shot. Also, what would I have to do to compensate?
If it makes sense, I would spend the money on an adjustable parallax scope, but for now, I'm trying to find out whether or not the non-adjustable is the right choice.
Thanks again.

M45, you could peruse Mcarbo's .22LR ballistic chart.

Based on my experience using CCI SV and SK Pistol Match on my rig, mine is approximately 7" (the drop) zeroed at 50 to 100.

That is the beauty of having mildots or hashmarks on your scope.

I do not click, hence I prefer my scope to have hashes or dots.

If you intend to shot really small groups, you would need to have a magnification of at least 16x, albeit I have friends who can do so with even less than that magnification--must be their eyes.

I have a 20x fixed mag SWFA MOA reticle on my 100 yard gun.

My experience with fixed parallax scopes.

Rimfire scopes set at 50 or 60 yards , really good at 50 or 60:yards. Blurry at 100 yards. Can kinda focus with the ocular ring, but then the reticle is blurry. Blurry at 20 yards or less.

Parralax at 100 yards. Good at 100 yards + = 20 yards closer or longer, blurry.


But my eyes are bad, and I am old.enough So all those little focusing eyemuscles are set to 18 inches for the computer screen.

I have some nice fixed parallax scopes , 50 yards. But after once using a AO , efr scope I will not buy another one, unless it comes on a used rifle I’m buying.

And yes the TM stocks can take a lot of scope

Hello again,
I'm new at this scope thing, I'm usually a bullseye pistol shooter. It's a red dot thing.
I think I am not using the terminology correctly. I'm not talking about zeroing the scope at 75 yards in the usual sense, I'm talking about the internals of the Nikon rim fire scope which has zero parallax at 75 yards.
At other ranges there is a parallax effect which gives the perceived effect of the cross hairs moving from side to side (off the target) when you move your head the same or opposite direction. I have heard that if you consistently keep your eye in the center of the scope, this parallax effect is minimized.
Since I have never shot a scoped .22 in any serious way, I was wondering if these distances, like 100 yards or 25 yards, or maybe even 150 yards, would present a significant parallax problem. Certainly high powered rifle guys, shooting long distances, wouldn't use anything other than a scope with an adjustable parallax knob.
Maybe it's not an issue at all. Just wondered if any of you have some comments to share about parallax. Thanks again,
Marv

Thanks for the comments, Toomany22s, I recall that some people have called that third knob, which adjusts the parallax, a "side focus" knob. That makes sense now.

Toomyman, I returned a 30mm tube with a 50mm bell scope because it was too big for my TM Avenger stock.

On a TM NightHawk BR stock though a 30mm scope looks just right.

Might change the rings to medium though because I find it a bit high.

I am a perfectionist, so all color themes must be in sync.
