Short side down because 11mm is wider than 3/8”, they always seem to come setup for 3/8” for some reason. This is your problem, just like pictures posted by McNasty.Jay308,
Short side up or down? Short side is now up.

I mounted an Optisan 3x12 on an HW95 using Sportsmatch rings. The scope arrived close to optically centered - was verified by mirror method.
Next step was to set up plumb line and at ~ 5 yards and align vertical crosshair. Did this to align bubble level on scope tube with vertical crosshair.
I then set up mirror 5 yards and align vertical crosshairs to centerline of objective lens and muzzle. I must admit that it not not easy to see objective clearly, but it looked close.
FWIW I also had bubble level on dovetail, which was also pretty close.
After snugging all screws down I took outside to have a look. Set up target at 30 yards and leveled grid. When crosshairs aligned with target, scope bubble level is off. If level scope bubble leveled, crosshairs are counterclockwise a few degrees.
Rechecked scope crosshair alignment to plumb bob and scope bubble level matches.
I suspect that scope not aligned to rifle bore resulting in cant error, but what is most sensible way to correct?
I have mounted many scopes on bolt action powder burners successfully and also one PCP. For some reason this springer is not working out.
That can give a guy a fit . Probably the hardest part keeping it from rolling when tighting no matter how even you tighten .. but old pre used rings it's not so bad as fresh new can be ..the scope can and will rotate as you snug down the rings,
always check and recheck in the mirror,
you cant check enough,
ill check/snug/check/snug etc.....
and have found,
depending on what rings im using,
that sometimes i have to align the crosshair slightly off center towards one edge of the bore or the other,
to get it to be straight and level after the rings are snugged down.
im sorry to burst your bubble,
but,
that super tactical dude doesn't have the slightest clue how to align the crosshairs to the bore the right way.
i only watched till he sat the big bubble level onto the turret and that was all i needed to know lol
It's actually the other way around. An 11mm dovetail is dimensioned to the outside, whereas a 3/8" dovetail is dimensioned to the inside of the groove. A 3/8" dovetail will typically measure 12mm - 13mm if you put calipers across it.Short side down because 11mm is wider than 3/8”
You still need the short end down, to keep it from canting on a 11mm.It's actually the other way around. An 11mm dovetail is dimensioned to the outside, whereas a 3/8" dovetail is dimensioned to the inside of the groove. A 3/8" dovetail will typically measure 12mm - 13mm if you put calipers across it.
The reason leveling from a turret cap is less than ideal is because the reticle itself (in the erector tube suspended inside the scope) may be rotated relative to it. Even premium scope brands may specify a tolerance of 2° to 3°.
The same is true of leveling to any external feature of the scope such as the flat underside of the scope midsection, which is the weakness of wedge leveling jigs like the one from Arisaka.
Ya, it’s always great to have crooked rings and have your scope at a angle…
Referring to the comment about a 2° to 3° tolerance between the turrets and reticle?LoL.. your sprit level ain't seeing that ..
I was just looking at the cheaper mechanist levels at Amazon .. for $25 or less you can get something useable .Referring to the comment about a 2° to 3° tolerance between the turrets and reticle?
Yeah, I was skeptical too until I experimented with a 10pk of cheap, short (25mm) spirit levels to our expensive digital level at work. And by cheap I mean $3.50 for a pack of 10. Surprised to see they were sensitive enough to easily distinguish a change of 0.5 degree, with a baseline accuracy of about the same.
