Running out of adjustment sighting in.

I'm having problems with a new scope.
The Setup
-Vortex Viper HS 6-24 × 50 Vplex
-Warne Maxima Permanent Rings Lows
-Weaver 1 piece Multi-slot Base
-Remington 700 ADL Varmint 22-250

I was using this exact same setup with a NcStar Mark III and did not have these problems. I recently purchased the above mentioned Vortex and mounted it up. I counted clicks both ways and zeroed the reticle before going to the range. I started out 20 yards away just to get on paper and was hitting insanely low.

I went back to town and got a laser bore sighter just to see what it would tell me. At 20 yards with the bore sighter I ran out of up adjustment before I could get the reticle zeroed.

I went over how the base and rings were mounted and nothing seemed to be out of place. I took everything apart and went over it again and I just can't find anything wrong with how the scope was mounted. This is all leading me to believe that the problem is with the scope itself. I've mounted and sighted in several scopes and never ran into a problem where my poi was so low that I ran out of up adjustment before I could find zero.

Any opinions or comments are greatly appreciated. Also if I need to explain something more please let me know.
 
Do you have the total movement in the scope that's its supposed to have? (Total adjustment in MOA or Mils)

Does the adjustments feel right when moving them? (Is it hard to turn or raspy feeling etc..)

Can you tell if the adjustments are actually moving the reticle?

Set your rifle up in a cradle, remove the bolt and look thru the bore. Center the bore over a small object that's 75 to 100 yards away. From home it could be done off the kitchen table looking out a window. Center the bore on a small object then using the adjustments on the scope, move the scope to the same object. Its really easy and if done properly, will put you on paper at 100 yards every time.

I've got a laser bore sighter that goes in the end of the barrel and a buddy has one that looks like a cartridge that goes in the chamber. Both are junk and will get you further from the target than the process I mentioned above.

it sound to me the the Scope is not level with the receiver. I would check rings and bases again. We had a similar problem with a friends Savage. He thought he had the correct base but as it turned out he had one for a flat receiver and his was rounded. This cause the scope to be mounted at a slight downward angle.
 
Place a mirror against the objective end of scope and look through,use turrets to bring the reticle images together. Go to range and fire one shot at 25 yards. 3 inches equal to about 48 moa if you are outside of your scopes moa adjustment range the problem is not the scope. If you are not outside the adjustment range and you cannot zero than the scope is not calibrating correctly.

This isn't a Savage.. The Remington 700 receiver is round, every 700 they ever made was round so when you buy a base for a 700 SA or LA... its going to fit, there's no mix and match like a savage.

There's nothing wrong with a scope mounted in a downward angle. We do it all the time with 10 and 20 MOA bases. The only exception would be an extreme down angle which is most likely like what your friend had.

Huh?
I'm lost at the 25 yards.. 3 inches 48 MOA thing.. Please splain it to me.

^ You shortened this one a bit too much also.

3 inches at 25 yards equates to 12 inches at 100 which is 12 MOA. (except for you decimal place nit pickers) So if the scope has 1/4 clicks that would be 48 clicks to 12 MOA and should be well within the scopes adjustment range.
 
Furhunter, the scope is supposed to have 42 moa of total adjustment. Which should theoretically equal 168"clicks", I started with the reticle adjusted up all the way and recounted coming up with 178 clicks or 44.5 moa of total adjustment which is 2.5 over what it is supposed to have.

The adjustments do feel right. It's the next morning and I'm not angry and flustered anymore and now reading your post the reticle did not seem to be tracking up correctly. I would turn for a 6 moa adjustment and get 1.

Just for a little better idea of what's going on. Starting out with scope zeroed in the center of its adjustment range I fired one shot at 20 yards. I figured out that I was low when the bullet struck the metal frame work of the target holder. I made an adjustment up and was still not on paper so I made another and finally found the bottom edge. This is when I could see that the adjustment were not corresponding with poi. I ended up moving up 17 moa and was still almost 10 inches low with only about 5 moa of adjustment left.

At this point is when I tried the bore sighter just to see if it was corresponding with what I was seeing at the range. Eventually I was able to reach zero with the bore sighter but it took every bit of up adjustment. Either way there is obviously a problem. It is the correct base, visually it looks right and I checked the part number with weaver. As mentioned early these rings and base worked just fine with a bottom line optic which leads me to believe it is the scope. Before I took anything apart I had my father in law look it over just to see if something looked out of place and it did not.

I'm going to give vortex a call and see what they say. Hopefully it's quick and easy to figure this out.
 
FairChase.

Remember if your shooting at 20 yards and you make a 6 MOA adjustment on the scope your only going to see about an 1.5 (or just under) inch change on paper.

 
Very frustrating. I may remount everything and give it one more go this evening just to ensure there wasn't something weird going on that I couldn't find.
 
I'm thinking that a 700 might need a tall mount and a short mount. In any case this is a good reason to try a set of Zee Sig rings. They can be adjusted with the inserts.

he said he has Weaver 1 piece Multi-slot Base. dont think a tall and short mount is going to work very well.
 
I've never had this particular problem, though the guy's bore sighter at the range sure would have made me think that I did a couple of weeks back.

lol. that right there is the truth. never had much luck with them. the laser types are worthless as obama.
 
The laser bore sighter was an after thought to compare what i was seeing on paper. From true center on the scope I started out somewhere over 18 inches low at 20 yards something about that seems strange to me in itself.

I just got off the phone with Vortex and the guy said I needed to try torqing the rings to 15 in lbs instead of the Warne suggested 25 in lbs. This would potentially solve the tracking problem however I'm not sure it would have anything to do with the poi being so low. They of course offered for me to send it in which I will do if the situation comes to that however if I can avoid having to send it off I will.
 
FairChase93,,,,,With the problem you are describing, you need to look at each part of the scope mounting process before assigning fault to any of it, especially an optic of reputable quality...

Place the rifle level in a vise with the ability to view an object at approximately 100 yards away...I used to use a neighbor's basket ball goal backboard as it had a nice square taped just above the basket rim...

Unmount the optic and using the process described above, center the reticle,,,Quote:place a mirror against the objective end of scope and look through,use turrets to bring the reticle images together. ....With the lower part of the rings open, place the scope in the bottom mounts and with the bolt removed, look through the bore at the object selected and then through the scope to see how much, if any, deviation there is between the two views..

Now you have a indication of the source of your problem, as if the reticle is centered and the action/barrel is reasonably level, you should have pretty much the same image in both...If not, then your bases probably need to be reinstalled properly...Just be sure that, if you have windage adjustable scope rings that you don't put too much concern if the windage is off until you adjust them until corrected for that problem...

If everything lines up in the process above, then it's time to take the rifle to the range for fine tuning your reticle to match the ammunition you are shooting...Just be sure that when you install the top halve of the rings and tighten them, that you are not putting an undue bind on the scope....If you have a 'inch pound' screw driver, see what the scope manufacturer recommends for torque on the screws/bolts....

I have a Remington 700 Tactical and used Burris Signature rings with the +/- 10MoA inserts to allow me to shoot 500-600 yards without adjusting my reticle too far off of center for gaining the elevation needed, but for shooting 100-200 yards, the adjustment is minor as well..
 
I had an issue where the bases in the set I had were different sizes could try that? Couldnt tell visually but my 22_250 wouldnt get on paper @ 50 swapped bases and walla
