I'm new to optical sights so I'm groping my way through this.  I purchased a used .223 Tikka T3 lite with a VX-ll 4-12.   The thing will group pretty well, easily under and inch, however attempts to zero the scope at around 2" high and with proper windage are frustrating.  It's say, 3" high.  So I bring it down 4 clicks and nothing happens.  The point of impact is just about the same as before.  A put in click at a time, then it's suddenly on the bull, 2" lower than I want.  It's as if the adjustments aren't received uniformly.  The same thing holds for both elevation and windage.    I'm using sand bags and settling things down pretty well for each shot as well as letting the barrel cool.   One other thing I noticed this morning is, at 12X if I move my head  around while settling down for a shot, it appears that the point of aim changes. Is that a parallax problem or what? 

 

When I got home I pulled out my 270 wsm and looked through the Sightron ll, and it does not appear to change where the crosshairs are positioned when I move my eye position.  Any obversations would be appreciated.

have you cleaned the barrel lately?

have your checked the pound of pull on your trigger?

these are things that can move you around on paper a bit.

If you are shooting at 100 yds + and keeping your head on the same spot on the cheekpiece you should not have much of a parallax error. Wind the dials fully up and down, left and right a couple of times.

When adjusting dial write past your setting and back up again. Say you wish to go 10 clicks down, move 20 down and 10 back up again. Tap the dials lightly with the back of an empty cartridge shell.

In other words I am guessing that the crosshairs are sticking and then suddenly jumping on the setting.

Yes.  The barrel was clean. The trigger is set at 2 lb and checks out.  The first 4 rounds were at almost exactly 3" high, and about 3/4" to the right.    I was experimenting with different brand of ammunition and this stuff was shooting higher than the previous batch did.   Those 4 rounds were within about 3/4 which was satisfying."  I then began adjusting the point of aim.   The windage was reluctant to move at first but finally settled in, almost perfectly vertical.  However the elevation just didn't want to move.

 

I like the suggestion of spinning the adjustments back and forth and tapping them.  The "cross-hairs-sticking" recommendation may be what's happening.  I'm not terribly enamored with the scope.  The glass is not nearly as sharp as the Sightron's and this little glich isn't helping me get over that shorcoming.   I'll try again.  Thanks.

Some Leupolds have sticky adjustments and a couple of VX-2s I had a while back suffered from this problem.  Bring a rubber mallet with you to the range and give the turret a light whack after making an adjustment.

However, if you do not like the scope and think you might not keep it, perhaps you should consider selling it and getting something else isntead of wasting time on setting this one up.

Excellent suggestions.  I called my brother, the former owner, in MT last night and he said the same thing.  He'd gotten in the habit of tapping on the turrets following each adjustment.  Apparently, as others noted, the adjustments are indeed sticky.  I think this scope is destined to find a new home in the near future. 

 

The rifle is intended for varmint hunting.  Coyotes in western WA, and prairie dogs in MT.  I'm wondering about using a fixed power scope for that.   The SS has attracted my attention.  A lot of the MT shooting is between 150 and 300 yards.   A 10X might be a bit light on magnification, but a 16 could work.  The guys I shot with last fall were using variables and in most cases they had them cranked up to the max, 14X or 16X, and even 24.   More shopping.  Gotta love that.
