Hey All,

I bought a Primary Arms ffp scope. It was a private sale but from a reputable seller.

The issue I'm having is setting the actual zero stop. Once I do i lose ALLOT of elevation, now I only have 7 mils or elevation to the upward position.

Could this be because I'm re-zeroing from an optic that was set and sighted in before me? And have to return the zero stop to the "factory position" before i rezero?

I haven't yet been able to figure this out on web searches.

Any help would be appreciated - thanks fella's!
 
I just took off the Zero-stop so I could access ALL elevation. Now I can shoot from 25 - 200 yds w/o issue.
 
I am no expert and I’m not familiar with Primary Arms scopes but I think the simple answer to your question is yes, you do need to return the scope to the appropriate middle starting position. Here is an excerpt from the Swarovski Z5 owners manual with describes how to do this. I believe it is the same/similar for most scopes.

“3. SIGHTING IN THE RIFLE SCOPE

3.1 BASIC ALIGNMENT
“…. check the correct position of the reticle. To do this, unscrew the screw-on caps of the elevation adjustment turret and wind-age adjustment turret. Now turn the respective knurled knob of the elevation adjustment turret and windage adjustment turret clockwise until it reaches the stop. Then turn the knurled knob back again counter-clockwise until it reaches the stop and count the clicks at the same time. Halve the number of clicks and you will have the exact. middle position. Repeat this procedure for the. second turret.”

As noted above, a higher MOA rail could also help but I would check the middle position in the manner described above first and adjust if and as necessary.
 
^ Yes, it could be that the prev owner had made a Large change to accommodate His rifle. You can also do the 'Mirror centre' thing; less tedious than counting clicks if your scope has a lot of adjustment . . . 'out to 150+ cliks, then back tp the other end, then back to 1/2 the total.
The mirror just takes a good eye and will get you within a few cliks of Centre for BOTH turrets at once.
 
I had never heard of the mirror approach. I searched it and found it to be very interesting and also found that there is a v-notch approach which apparently is most accurate method but can be done only if scope is off the rifle.

Just going to echo re-centering the scope. Someone could have had a MOA rail on the rifle that sent the scope to one end of its adjustment with the Zero Stop active, maybe?

What are you using for a rail? You could get a higher moa rail to gain some more elevation.

just the stock savage 10 rail. thats an option but shouldnt need to do that. i had so much more elevation adjustment prior to setting my zero stop, and im shooting under 800m nothing crazy like 1km plus
