    I took my Marlin 22 LR with Tasco 3-9X32 scope to the range this morning and put some holes in the paper. When I sighted and zeroed this before I used the lowest magnification. How come when I use 3x my groupings are good at 50 yds but when I put it to 9x I was all over the place. Does it have something to do with the scope being cheap? Would Leupold also have the same result.

    Do I need to re-zero it again and use 9x?

    TIA,

    I am by no means an expert in the optics department. However, I've always been taught to sight a weapon with the scope at the maximum magnification setting, in your case 9X. After the weapon has been zeroed you then adjust down to the minimum setting and the group should still be on. I'm not saying this is the only way to perform a sight in, just the way I was taught. As for it being your scope it may be a possability. However, I've used both ends of the spectrum when it comes to optics, high end Leupold's and $39.99 scopes from Wally World and both sighted fine using the above method.

    A lot of cheap scopes will do that… their design is the culprit.

    I once read a very good article about this that explained why & how it happened… I can’t find it now. Basically it has to do with how the scope was designed to ‘zoom’ & where the ‘crosshairs’ are located in the scope.

    Nothing can be done about it… some are worst then others though; even within the exact same scope line/manufacture.

    Sounds like you got a REAL bad one… that scope is no good.

    Thanks for the replies, I'll just sight it again using the highest magnification.

    Since this is in the hunting forum, I'm guessing this is a small game gun. I wouldn't even worry about 9x. I have a 2-7 variable on my hunting .22lr and it sits on 2x. When you get above 4x that little rabbit turns into some kind of Godzilla beast filling up the entire field of view.

    Just my $.02

    The 3-9 Tasco is parralexed (sp?) at 100 yards. By shooting at closer targets you are throwing the shot's relation to the reticle off by a couple inches. With a .22 the result is significant and the movement can change based on how you look through the scope. To solve it, leave the zoom at 3-5, or be aware of your eye whe you look through the scope. Make sure you look through it the same way each time.

    Don't worry, i had this same problem.

    Yes this will be used for small games and a lot of plinking.

    A question for ILikeFTLBS, Wouldn't the scope be a 22 scope if it is 3x9x32, therefore parralexed closer than 100yards? I am not doubting your statment but asking for my own information. I just thought all scope that were 32mm were 22 scopes. Thank you for your reply in advance.

    I'm not ILikeFTLBS, but can answer this for you... a 32mm scope is not a 22 caliber only scope. Objective size has nothing do with gun, caliber or parallax.



    By the way, most good scopes are “parallax free”.

    I can defiantly see how it would look that way... a lot of 22 labeled specific scopes are 32mm.

    That doesn't seem optically possible to me.

    Often they'll say they're parallax-free at a certain range, such as 50 yards for a .22 specific scope or 100 yards or 200 yards for a more major caliber. Some of the more expensive scopes have adjustable objectives that allow you to change the point at which it's parallax-free.

    You also need to remember a scope is more forgiving when set at a lower setting, ie: 2x as opposed to 9x. Each movement is exagerated at the higher setting thus causing your shot to move that much more. Example, if you pull the trigger instead of squeezing it the amount of pull is realized at a greater rate on the 9 setting than when on the 2 setting.

    Good luck!
