Does anyone know the Unertl scope clicks and which ammunition was it calibrated for

The scope is cammed to 800m.

IiRC the elevation is in 50 meter increments with a plus and minus 3MOA fine adjust in 1/2MOA clicks.

42. Elevation and Deflection Drums. The drums are graduated in machined increments to
facilitate simple adjustment of the sight settings. Elevation settings are set to the trajectory of the
bullet for the given range with a fine tune of 3 minutes of angle (MOA) up or down in
increments of ½ MOA. The deflection drum allows adjustment of 8 MOA left or right in
increments of ½ MOA.

54. The main ballistic come ups (for the service match ammunition) are built in to the main
elevation adjustment. The elevation scale is graduated from 100 to 800 m in 100 m increments.
Targets at 900 m may be engaged by dialing 800 m and aligning the first mil dot below the cross
hair on the point of aim. For ranges between the set range settings, set the dial halfway between
the range settings (e.g. for 650 m set the dial halfway between 600 and 700 m). There is also an
elevation fine tune of +3 MOA to allow for different temperatures, ammunition lots, types of
ammunition, and differences in shooter’s zeros.
55. The windage drum allows the sniper to apply corrections of 8 MOA left and right as
required to compensate for windage deflection.

Ammunition was Norma loaded with 168gr Sierra match kings, probably the "diamond line" as velocity has been the only complaint I've heard.

Actual average velocity has been reported between 2450 and 2550 fps.

The book states:

NORMA MATCH AMMUNITION
67. To ensure consistent accuracy with the sniper rifle the sniper must use Match grade
ammunition. Norma match ball is the only current match issue ammunition.
68. This round was selected for sniping because it is manufactured to a higher standard of
quality and is more consistent than normal service ammunition. The component information for
this round is as follows:
a. caliber 7.62 mm;
b. muzzle velocity 2,680 fps;
c. bullet weight 9.33 g; and
d. case length 51 mm.
69. In the event of an emergency, the sniper may fire normal 7.62 mm service ammunition,
but it must be accepted that accuracy will suffer. Since the consistency standards of the service
ammunition are less stringent, the trajectory of service ammunition will vary slightly from round
to round, and will result in an increase in grouping size at all ranges.

Thanks for the help, I had it on six clicks on the windage on sunday at 300 mtrs so 3 moa.

Is the middle rifle an M85 with standard bottom metal?

Some other data if any one is interested in Match loads.
I have not loaded any of these loads so the usual applies chaps start 5% lower and work up I take no responsibility with the load data

Lovely set there.

On the topic of the Unertl 10x, does anyone know if the C3 Scope was threaded for a ARD/Kill-flash?

Thanks,

Hello Kevin,
The C3 Unertl is not threaded to accept a screw on ARD. A special adapter was used to slip over the objective that allowed for an ARD to thread into as depicted below. There is one for auction currently on GB.
