curious as to how many when setting turret back to zero after dialing elevation turn past zero then creep up to zero?.think that might be a problem for me[not doing it] zero will shift after a few shots. zero'ed then shot at distance turned turret back to the 100yd zero and was .2 high, then corrected by turning turret and went 2 tenths low. after a few more shots[maybe 4] was at the original zero. thinking if I go past and work up to the dope I will eliminate that. thinking the springs might not of taken a set. am I correct in this?

I read that 4 or 5 times before I understood what you were trying to say. Is it a cheap optic? I've seen cheap optics that you had to bang of the turret after any adjustment, or they wouldn't move at all. In fact, I still do it out of habit every time I adjust a scope during zeroing. I'll make my correction, then tap it a couple times with a cartridge or an empty case. I grew up shooting tasco and Simmons scopes.
This used to be common, or atleast people would say it's something you should do. With older scopes (say 10+ years ago) dialing wasn't as common as it is today and weren't necessarily super reliable, so this process was meant to increase the reliability.
Its an issue because when dialing up you are decreasing tension on the erector springs, and dialing down increasing tension. By always dialing up to your dope you are doing the same things consistently.
Similar to how people used to always tap on there turrets when zeroing to try get the springs/adjustments to settle in before shooting.
I'd say any scope (that isn't very cheap) that is newer than 5 years old it's not much of an issue. Maybe some of the older hunting designs VX3/Z5 etc might not dial accurately still, but even the likes if the Leupold VX iii/3/3i/3hd has seen a lot of updates over the years, so this process is probably less necessary.

There are a number of scopes out there with perceptible lash. I think the largest I have encountered is ~.1 mil with both the Minox LR and ZP5. Any scope with a non-translating turret (the elevation knob does not raise up and down when the turret is moved) will have some amount of lash though it is usually neither measurable or even perceptible when using a collimator or similar test apparatus. If you as seeing a .2 mil issue it could be this or you may have some binding of the joint that the erector tube pivots on. This is usually caused by the rear ring pinching the main tube too hard directly over the joint. If you move the ring and decrease the cap screw torque to 15 in-lbs it usually solves any binding issue. Lash issues are design and manufacturing aspects of a particular scope and can't really be solved. You either have to learn to turn past and adjust back or maybe just switch optics.
Ah, the old Tasco tap.
I remember those days.
Kinda like a drunk stepping on a cigarette. There was a bit of a tap dance, but eventually it would stop.
Once you got it zeroed, it would stay there.
Which scope are we talking about? Yeah, some older scopes need a little jarring after dialing to settle the erector.
