Hi everyone,
I’ve got a S&B in Optilocks on a Sako 85, bore sighted the scope and found I was dubious about how low it was and after factory and hand loads it’s still 7” low at 100yds and the dial is on the stop of the vertical adjustment. Windage is near centre, all the hardware was torqued properly etc.
I’m pretty stumped so if someone has any fix’s for this or any advice I’m all ears, thanks in advance.
Are you getting any vertical adjustment at all?
What would happen if scope was turned 90 degrees so windage becomes vertical?
Yes, I started by winding it back to centre of the windage adjustment and shot it, was very low and worked up until I ran out of adjustment but still too low. It needs to be 3.6” high at 100yds for the load I’ve got and I don’t want it sitting against the stop eitherQuote:

May have to shim, the mounts aren’t able to be swapped aroundQuote:

What he said. Try unscrew elevation dial. Lift off and place back with "0" back at the original position before retightwning screws. This should give you another dials worth of elevation.
From memory the S&Bs have a small dial in the turret that shows how much elevation is left and it sounds like Uplander is saying it is indicating it has bottomed out.
Uplander have you got another scope you could fit just to see if it is your mounting system or a fault in the scope?
Are you sure you don't have an out of spec mount holding the scope?
I have seen that before.
Try another scope on there and see how you go,or measure your mounts against another set of identical mounts.
Yep, try another scope before anything else, will eliminate the rifle or the scope, much easier less mucking around
I put the Contessa rail on and different rings, sat up quite a bit higher but still way to low. It’s also for sale but mounting g up in the mean time to see if it’ll do
Ok
I’ll offer 1000 bucks for the scope and rifle as is.
Will take the risk that I can’t sort it.
:)
Can you post a bit more detail of the scope model and mounts ?
Have either the scope, rifle or ammo ever shot better than this ?
I once had trouble with 2 piece optilocks where the big screw holding the rings onto the base had come loose after 1000 rounds. Shots were going about a foot low but inconsistently. Wasted a bit of ammo and it took a while to find. You dcant see it unless you take the base off the action. The scope did rattle in the end. Tightened the screw and it’s fixed.
Could you also confIrm whether you’ve checked there isn’t a whole lot more adjustment range available if you shift whatever zero stop mechanism you have ? A scope will usually have over a metre vertical range at 100m.
Sorry, I'm not wanting to hijack your thread - just offer encouragement that it'll be something simple you can fix yourself.

Uplander,
Work through each item as discussed above to determine where the fault lies scope, rings or rifle.
If it is the rifle and it is new then talk with Beretta. I have heard of barrels not square with action faces on the odd occasion even on Sako’s. You should not need to shim a new rifle.
Chris, I think the mounts Uplander is using are the Optilock ringmounts as shown here. https://www.nzhuntingandshooting.co....-bender-56500/Quote:

The 30mm ringmounts do seem to come in just one height and for the 30mm Version and it’s better suited to a 50mm objective.
Leupold List a lower one suitable for 40 or 44mm obj depending on Barrel contour.
There’s not much can go wrong with those one piece ringmounts. Perhaps it’s the plastic insert causing problems ?
Has any work been done on the rings or the barrel in the past ?
