Tikka T3 and Zeiss V4 zeroing advice please

[NickJL]

I’m hoping you might be able to help the ‘new boy’ here. Just picked up my Tikka T3, Zeiss V4 and Optilock Low mounts. Went down the range to run the barrel in and zero up. Bullet impact a mile above the cross hairs. Dialled as far as the scope would go. Bullet impact still shooting a mile high. At least 12 inches. Shooting at 50 yards initially. Tried switching the rings around but made no difference. Bases have a front and back because of the retaining pin so couldn’t switch those.
Tried taking the ballistic turret cap off and giving myself more winding down on the scope but now at max and the bullet is way high. Not even on the paper (it’s an A4 sheet and I am aiming at the bottom).
I did also try winding the scope entirely the other way in case I was being a numpty and going the wrong way. I wasn’t. That made it worse.
My much anticipated afternoon on the range (having just got my FAC) sure had the shine taken off it taken off it!
Any guidance on what to try next is much appreciated.

New scope? New rifle? Bought from an RFD?

You do know the ASV needs to be removed with a small Allen key for zeroing? Then replaced once you are zero’d.

if yes to the RFD take it back to them and ask them to put it together properly.

if bought separately you can still take to an rfd and they will just charge.

Sounds like a problem with the mounts. Optiocks have various variable bits that need putting together.

If you know how to bore sight then you can do this to test your setup before heading to a range.

The rear of the scope may be mounted too high.
Remove scope and rings.
Clean receiver dovetails and bases.
Check nothing is holding the rear base up. (blanking screw etc)
Set Optilock rings onto the bases ensuring that they are seated and tight.
Refit bases, make sure both are hard down onto the receiver. Torque clamps to 45in lb.
Fit plastic inserts onto scope body,and lay scope onto the ring bases. Turn plastic inserts to the align the splits with the top of the bottom rings, both the same side.
Refit top rings, tighten down until they are tight, loosen ring cap screws so that you can set eye relief and square the reticle. Torque down rings to 15in lb.
Remove any zero stop adjustment on the elevation turret.
Then bore sight the scope. That should get you onto the paper at 50 yds.
If there is still a problem try a different (proven) scope.

Thanks guys. I’ve done what I can from home with removing and reseating the mounts and scope. I’ve changed the gap in the plastic rings to both seat at the bottom of the scope. I’ve bore sighted as best I can but garden isnt massive.
I did remove the ASV yesterday but had no joy. I still think it’s something I’ve done wrong so I am hoping to start afresh today and take the other steps you’ve suggested.
it is a new rifle, new scope etc. I bought the scope and mounts from a different place to the gun so hoping I can sort.
Thanks for the advice. I will let you k ow how I get on.

Just a thought ,did you fboresight it first

 

[mealiejimmy]

Boresight it and then set up a target at 15 yards.
That way should at least be on paper when you fire at the target
Zero the scope at 15 yards and only then move back to your desired zeroing distance, where you can fine tune the zero settings

Cheers

Scope has a zero stop you need to reset that? It should do just fine…. If all else fails 20moa mounts but most likely something is up usually human error in my experience.

Watch this video to zero your scope after you have checked the mounts

 

[Yorric]

Nick, If you put the split in the plastic inserts at either top or bottom dead centre, rather than both to the one side, the result is that clamping forces that have to overcome more sliding / friction between the rings, the scope and the inserts are greater and mounting is more problematical. --- It sounds a bit illogical, but it does make a difference. (not saying that is the cause of your problems though!)

Thanks folks. That did the trick.
I took everything off. Put the scope back on with the gap in the rings facing down on both the front and back. Counted the elevation clicks so I knew I was bang in the middle of the adjustment. Bore sighted at 15 yards before I went to the range. First shot 4 inches off zero at 100 yards!!! Big relief. Little bit of fine tuning and spot on.
I’m I think my next set of questions will be about reloading given the price of ammo

Too right Nick, prices going up and perhaps more with all this copper malarkey
