Rifle Scopes How many use the zero stop washers on Vortex PST

Re: How many use the zero stop washers on Vortex PST

I use mine. Not sure how necessary they are... But the zero stop really makes it easy to return to zero after dialing up two or three revolutions on the turret.
 
Re: How many use the zero stop washers on Vortex PST

I use mine too. But, when installing them on a scope I sliced my finger pretty good and bled for hours. Kind of like a deep bad paper cut.
 
Re: How many use the zero stop washers on Vortex PST

If you dial any at all then they are very useful. I used mine without for a couple months then after installing them will find it tough to use a scope without a stop of some kind.
 
Re: How many use the zero stop washers on Vortex PST

Decided to play around with the lathe and made a couple of thick shims rather than stacking up a lot of thin ones. I finally settled on the nylon unit at the bottom that snaps around the shaft and wont fall off. Probably no better than the stock shim pack with the grease. 0.920 OD x 0.625 ID

Re: How many use the zero stop washers on Vortex PST

I never really thought that I would need the zero stop shims but I decided I would use them before I went to thunder valley precision. I am glad I did use them the first time, I couldnt even count how many times I lost track.

I now continue to use them and will probably never buy a scope with out zero stops.

thats pretty slick.
 
Re: How many use the zero stop washers on Vortex PST

I use them on mine(4-16x50 ffp MOA) installed on a AA 24" Grendel, only had 2 shims left over and it stops between 2 and 4 MOA past 0. I like them, I own a few sightron SIII which have the turret scale with 0 on the center and 1,2,3 in both directions (up & down) and I didn't have to adjust more than 5 MOA elevation to sight in so they are right on the 0 mark so no issue returning to 0 after dialing.
 
Re: How many use the zero stop washers on Vortex PST

I do and find them useful. After I set the knob to zero, I go up about .5 mils then install the stack. This allows approx 2-3 extra shims so the knob stops a more solid at zero.

Re: How many use the zero stop washers on Vortex PST

After installing the shims how do I get the bottom of the turret to line up with the the first vertical line on the elevation? I put them on my dads pst and would things to line up better.

You don't. The scale is absolute so that is why you need a settable zero.
 
Re: How many use the zero stop washers on Vortex PST

Had a weird thing happen yesterday to one of our Vortex Viper PST 4-16 FFP scopes. We have one on a LR pistol for our 1000 yard matches. For the past year it's been flawless including the place the Zero Stop goes down to. Usually it stops 4 moa past zero the way we have it set and it's stayed exactly there since it was installed. Yesterday about halfway thru the match he cranked it down to zero to reset for a 720 yard target it stopped at +1 moa and he thought maybe the shims compacted more than usual and went farther down than usual.

He came up past zero again and up his usual amount and spotters said "no call" didn't see anything and at that distance we usually clean those targets. He rechecked it again and came up same amount and same thing, no call. He did it again and came up based on that +1 and centered it. It was in the 90's and seemed the temperature either swelled the shims or something inside and wouldn't allow it to go down to it's normal zero stop.

Later that evening we tried it again it was back to normal. Never happened before so we'll have to keep an eye on it and see what might of caused it. Before this we couldn't be happier with this scope and the way it functions. Love the zero stop which makes it easy to recheck your settings if you feel you might of gotten lost and worry about being a turn off.

Re: How many use the zero stop washers on Vortex PST

Topstrap,

My 4-16 PST did the same thing to me yesterday at Rayners. Usually when I dial it down, it allows me to go about 1 mil past zero. At the match on Saturday it had my almost one whole rev off. Luckily something didnt look right and I kept messing with it till it went back to zero. Messing with it again today, and its still messed up, and will work properly one time, then be way off the next. I pulled the turret off to see if the shims looked jacked up or anything, but nothing looks wrong. I really dont know what to make of it.

I think I would call Vortex and start using the best Customer service in the industry. They promise to me "replace or fix" a PST i own and (different problem)I had a brand new one in 7 days.

I commented on a different post about mine not being repeatable on the zero stop and that is exactly what I was talking about. Also the illumination on mine sometime goes off with recoil, I installed a paper shim between the battery and the cap holding it and it hasn't happened since. I have never used or needed CS for a riflescope issue but I probably will this time
 
Re: How many use the zero stop washers on Vortex PST

I plan to and don't see why you wouldn't unless you weren't planning on dialing. Installation doesn't look bad.
 
Re: How many use the zero stop washers on Vortex PST

Installed mine yesterday...took 10 shims I believe.

Crude but very effective zero stop. Mine will go past zero .4 mills.

Re: How many use the zero stop washers on Vortex PST

If your zero stoppish is dialing past zero, add the number of additional clicks to your zero click value and reshim.

Example: Lets say we shimmed our zero stoppish, but its going .8 mils past zero. Dial elevation to .8 mils, remove the turret knob, and reshim. When you replace the knob and dial back down to zero, the turret will reliably stop there. Don't forget to stagger the shims evenly, it seems to make a difference.
 
Re: How many use the zero stop washers on Vortex PST

I tried mine....took them out right after shooting with them. They would pass zero and were stiff if you went all the way down. (4-16X50)
 
Re: How many use the zero stop washers on Vortex PST

After adding the shims you will find that they will settle some, so if your stops would allow you 1mil past zero in time as you run the scope the shims will intermesh and you may end up 4 mils past. You can at this point add a few more shims and you should be fine. You will find that if you grind down hard into the shims once in a while that it may seem a little sticky running back up to your zero. In time they all find there place.

I would always use a few shims versus nothing, this will protect your erector spring from being collapsed or crushed when you run it down till it stops to find the bottom.

Also anyone using 40 moa rails or combos to really stretch out the distance, it would be advised to turn your turret up some when done shooting and casing up, so here again to take the squeeze out of the spring that’s being compressed tight when running a turret right to the bottom.

Pushing down hard on a zero stop seems like a bad idea. Those are some mighty fine threads doing a mighty fine precision job.

I agree

But the point was – that there may be a time when a person unintentionally runs into the zero stop shims a little hard thinking he had another rev to go yet. This can easily happen when working a position with multiple targets and under pressure and old age for some.

The whole point of my reply was to mention the benefits of having the shims in and also some info for those who run a lot of base. The PSTs are great scopes for the investment just passing some info along.
