Possible wrong scope ?
« on: March 23, 2011, 03:36:43 PM »
I have a H&R Sporster SS1 in .22 magnum with the H&R scope rail. I mounted a NC Star extended eye relief scope. The groups I fire are not what they should be. I wonder since this is not a designated .22 scope , that the paralax is off as in it is not compatable with the .22 mags shorter range and quicker drop. What ya think , get a .22 scope on it ?

Lay the rifle in a stable position in sandbags or on a rest, then without touching the rifle, look thru the scope at a target or distant object at the range you're shooting at, as you change your eye position away from center slightly, the crosshair should stay in the same position on the target, if it moves around, you're seein the  parallax error, centerfire rifle scopes are parallax free at 100-150yds depending on the mfr, rimfire scopes are parallax free at 50yds, so a CF rifle scope isn't the best for a rimfire at 50yds unless it has an adjustable objective that can be set parallax free at any range. The only way to use the CF scope is to make sure your shootin  eye is in the in the same identical spot(consistent cheek weld) each time you mount the rifle, otherwise the parallax error will show up in your group size because the point of aim isn't identical each shot.

Smokeye- (and other posters) please indulge me if I missed something-you stated you installed an Extended Eye Relief scope-right?  It has been my experience that EER scopes are intended for mounting on handguns/Rem XPs/Savage Styker/Ruger Charger type weapons.  I have at least 6 EER scopes on a Ruger Charger/2 Strykers, a Rem XP-100, Ruger MkII .22 and a Walter P22.  They are ment to viewed at arms length to get the full sight picture.  Any regular "rifle" scope should work just fine on the H&R (BTW I have 2 of those, a 308 and 17HMR and b oth are perfectly served by common rifle scopes w 33"-4" eye relief). Quickdtoo's post should fix you right up with a rifle scope!  Good luck.

Of coarse you are correct, and many of these EER scopes have a shorter parallax as the rimfire scopes do. But with some of the cheapo scopes (Like the NC STAR) have really parallax issues. Some of the stocks that come on our handis do not lend themselves to good shooting ergonomics amplifying the issue.
Some guys just like the looks of a slightly forward mounted scope. Some shotgun scopes will work, some intermediate eye relief scopes do too. But usually these are usually more expensive. The pistol extended eye relief scopes are available cheap and expensive. Some work acceptably for the 8" or so a slightly forward mounted scope on a handy.

If your not familiar with what I'm talking about. Weaver makes a handy/H&R mount that is long and pushed slightly forward. With a cheapo 2X20 shotgun scope you are able mount it so the ocular objective sits even with the barrels breech. Makes for quick shooting, as like  cooper scout setups you can shoot it with both eyes open, have lots of clearance to load/unload rounds and of coarse extra eye clearance.

BTW, I read your post in the 40 S&W popularity thread, thank you for your service!!

Buy cheap get cheap. Upon closer inspection , its the scope ! I have another of these NC Star EER scopes mounted on a Mosin Nagant 91/30 as a scout scope. The one on the MN is a year older and has held zero well over many rounds. They must have found a way to make em cheaper. I compared the two scopes in a rest and the one on the H&R is not correct. I will pick up a center fire 3x9x40 AO scope and that should do the job. Thanks guys.

#1- To CWLongshot-  Thank you very much, as a VietNam era  Vet ( per the VA) I was active duty 65-85, I have seen a much greater national response to our vets than the "real VietNam Vets" that came back in that era.  I
left the military in "85 and spent 21.5 yrs as a state LEO and did my best to support the troops (m&f) I came across  in the line of duty.  (To the Moderators- Forgive my excursion off topic-chastise as due)- as a DAV w/a spouse who worked close to the VA system, I am really concerned for the current Vets with PTSD & such from the current conflicts  Besideds 4 yrs in SEA I was in Libya 2 yrs!-When QueerDafy took over from King Idris in 9/69!  So I got 2 bites at that cookie for thanks-Ever so humble to have been there, done that, got the tee shirt, and how do I really feel about it? When I hear the National Anthem played- I cry.  God Bless America.

Sorry I got off topic,  when you get a "regular" center fire" scope for the rifle , post us again.  I feel sure you will be "on the mark"

Well it now wears a Barska 4x16x40 AO varmint scope with a fine crosshair reticle. Maybe a little too much scope - but the price was right. I have a larger version of this scope on a swiss K31 and its sweet and durable. And as expected , accuracy is greatly improved , allthough we have only zeroed at the 50 yd mark so far cuz the glacier has not melted yet at the longer range berms. Someone said spring is comin....maybe that was a mean April fools joke. The snow is still a foot deep in my yard.

I think this time last year Tim said he had mowed 9 times, I think he's had too much recoil ;D My yard is like a swamp now.

I put a little 2-7 Leupold on mine but haven't tried it yet. Couldn't get very good groups with it before with a Tasco. It better shoot now or I'll be talking to cw about it ;D
