Scope bottoming out

Hey all, I'm having some issues adjusting a new scope I recieved. As the title says, the scope is bottoming out, i.e. I ran out of elevation adjustments and the rifle is still shooting ~10-15 inches high at approximately 90 yards. Any input would be appreciated thanks.

Shooting tikka t3x laminated stainless .308 winch
Vortex crossfire II 4-12 x44
Leopold std for tikka mounts
Leopold std low rings
 
The bases are identical/interchangeable, correct? They are the same thickness? Stand back and look at things and make sure they look right.
 
Thanks for the input everyone. I used the bore sighting method and was able to get everything to line up, however it was still shooting high. Bases for this one are not identical so it wouldn't be a mix up of installing them backwards or something of that nature. Going to stand back and examine it very closely, however, at this point it does appear it could be a scope issue. Thanks again everyone for the input much appreciated.
 
You probably know about Vortex's excellent warranty service. It's pretty quick and easy to go through, I did it once. But it might be too tight to get the new or repaired one back before deer season.
 
Silver linings I guess. If it is the scope vortex has me covered. But it would be a bummer to have it stored for the rest of year as I don't have another optic to mount on it.

Unfortunately, the razor line appears to be the only dependable line they offer these days. Maybe some viper models, but I won’t chance it. I was once a vortex fanboy. Razor gen 1 and 2 including the AMG are nice units. Everything else just all kind of blends together now…
The warranty seems to just be another generic, lacklustre feature they attach to all their products.
 
Are the Leupold bases directional? Meaning is one end supposed to be placed closer to the muzzle than the other because they are sloped? If yes, do you have them both installed facing the right direction?

You might want to consider switching to a different style of base and rings before you blame the scope. Warne makes a 2 piece set of picatinny bases for Tikka ($40 at Cabelas). Standard 1" picatinny rings are available from a multitude of manufacturers.

Vortex says the scope has 50 MOA of elevation adjustment. That should be more than sufficient to zero it at 100 yds with 0 MOA bases and rings.

+1 here. Sadly they just aren't what they used to be. I had a few early Viper PST and HS series scopes and they were great, but quality seems to have deteriorated as of late, and prices have increased. All I have left are my Razors and a Sparc Solar now.
 
count the clicks , total for elevation then windage. halve it, thus centering the reticle, with bottom rings mounted, and rifle in a solid mount(will not move) find something to sight on. not your neighbours house. place sight on rings, sight and rotate. crosshairs should remain close to center. if they make a big circle when rotating, the scope is off. if only a bit off, look at base and rings. measure with calipers. some recievers can have a slight taper( loose machining specs) measure with calipers. is it a solid base ? if so, screw one end, check the other end for slight gap. then check the other end, with one screw. the best rings will only transfer errors in the base and reciever.

Yes exactly, 50 moa should be way more than enough . I'll carefully inspect the base and rings and will probably just remount everything again. What irks me is that I had no problem bore sighting in terms of adjusting the reticle, it was just once I started shooting it was way off on elevation.
 
If possible level the rifle in a vise.
Then with a level see if the scope is slanted downwards at the front. It has to be...
