Rifle Scopes Tangent Theta TT525P Troubleshooting

[Boogeyman]

Looking for some input from Tangent owners on the hide here.
Recently mounted up my first Tangent and only getting 15.5 MILS (one full revolution) of mechanical travel in the elevation turret.

-Tangent Theta 5-25-56 TT525P
-20 MOA rail
-NF xtreme duty ultralight rings 1.125” (lapped and bedded - 2” scope height
-Kelbly Atlas Action chambered in 6.5 SAUM
-Proof Sendero barrel

I have ran FFP ATACR’s on all my rigs including this one. On this action so far a 4-16, 5-25 and 7-35 all milxt. Was getting much more mechanical adjustment on the NF scopes.

Question for other tangent owners here is how much mechanical adjustment are you getting after zeroing your rifles on these tangents?

I called and had a pleasant conversation with David at armament today. We troubleshooted the optic and am sending it back for them to look at upon my request. He told me one solution would be to put a 30 MOA rail on but that would only get me a couple more mils of mechanical. Super happy with the customer service, armament in general, and the build quality of the scope. Just want to mount it up on a 300 Norma being built and try and get 20- 24 mils mechanical out of it.

Hoping someone might have some ideas or input on where I’m going wrong here.

David's super cool. That's all I have to add.

The TTs have only 28 mils if I'm not mistaken. So your at 14 right out of the gate. 20moa is roughly 6 for round numbers. If everything on your rifle was perfect for zero you would have little less then 20 mils of come up. Your rifle may take a few mils to zero it regardless of what scopes on there.

The 7-35 NF is known to have up to 35ish mils of adjustment. At least the ones I've had and the guys I shoot with have. So that right there is 7 more then the TT if your comparing the two.

Editing to add: Not sure why the rings were lapped and bedded. Not needed in my opinion with those NF. But inconsistencies with that and or the bedding could account for any difference your seeing. I would be the scope comes back fine.

Not sure if lapping the rings would directly impact that, but you shouldn’t ever bed/lap quality rings. I’d look there. I know you said you’ve had a few different NF in there, but it may affect the TT in a different way. You could always try to get a 30 or 40 moa base instead of the 20.

I'm getting 23.5 mils mechanical.

20MOA rail and an additional 10MOA in the mount. Also running 1.5 tall Spuhr. Scope height around 2.375.

I’m getting 20.5 mils elevation with Hawkins heavy duty rings on an Impact action with my tangent 5-25

 

[nfoley]

For reference my Nightforce 7-35 atacr on an Impact action with the same Hawkins rings has 21.2 mils elevation left after zeroed

Agreed. Gentleman and a scholar.

I would assume the scope comes back fine as well as David mentioned he’s only heard of this one time out of 100 from another client. I still want love this optic. My wife and I are leaving to montana next Friday for a hunt and I wouldn’t run anything I’m not confident in on an animal, so sent it in with the rings for them to take a look at and thru back on an atacr.

Is that the sp-4302?

Hadn’t noticed a detriment on my 7-35 atacr with the lapped and bedded rings Piercision also did but good point here.. I’ll throw the TT on a set of OEM NF rings I have still in the box tomorrow and see if there’s a diff. Thank you.

 

[Perceptiv]

Out of my 4 TT 5-25s I range from 18.5-21 mils of travel left after zeroing my scopes. All on 20-30 moa bases.

Yes

 

[Boogeyman]

Mounted up a 20 moa spurh to try tomorrow.
