Out of down elevation - MDT ESS w/ X-high Elite MDT rings

[TikkaTenderfoot]

Quick summary - @100yards - shooting 4-5” high & scopes out of downward elevation....SUGGESTIONS?


Just finished assembly on MDT ESS chassis for my Tikka t3x in 7mm rem mag. Have a Steiner 5-25x56 mil dot mounted with MDT Elite x-High rings (1.5”) & high MDT 20MOA rail.

Took to range today to sight it in today. Bore sighted at 25yards, loaded a round and smacked about 1/2” low right. Shot one more round out at 100yards and adjusted windage and dialed down elevation after round hit 8” high, 5.5” right.

Windage is A-ok but scope ran out of downward elevation...

Tried couple more shots and they were all 4-5” high still.

Been doing some reading/investigating online and leaning towards shimming the rings but I’m curious if anyone has any suggestions before I go this route.

Rail is only able to be mounted one way so not problem... swapped front and rear rings in case ones out of spec, same shot result. Checked torque (in/lb) on action screws, rail screws, scope ring screws. Same result...

Should I zero at 300yards and call it good? Overall scope height shouldn’t cause this should it?

Check your manual. Possibly your zero stop has been set

Damn... feeling little stupid. Went out to range with all the tools for chassis and rings but forgot my little set screw allen key.

Will try that tomorrow!

Good chance the zero stop has been set. If it isn't that; then you have a good example of a rifle that didn't need a rail in the first place.

Likely another rookie question but are all tikka action screws the same? I need a replacement set and would like to get torque bit ones...

Looking at mountain tactical ones, but would they be right length for an MDT Chassis!?

loosen fore end screw .take 12 gauge shot sheel cut brass and crimped part off cut shell in half, take one half and insert between barrel and fore end tighten screw ,if not enough double it .shoot at 25 yard,s to start

Don't shim the rail, you'll bend it when you tighten the screws.
Possibily silly question, but can you put a tikka rail on backwards?

Tikka action screws are different than say Remington, your scope has a pile of elevation adjustment, you likely just have to move your zero stop. Just refer to the manual and it should solve your problem.
