The range lever on the S.U.I.T. scope gives a ranges of 300m and 600m for British 7.62x51mm L2A1 ball ammo.
Israel re-marked their scopes for 5.56x45mm M193 fired from an M16 at 250m/450m.
I did some figuring... The lever moves a cam that depresses the scope 11.24 mils.
A 25 yard zero with the lever to the rear is also a 300 yard zero with 6.8x43mm SPC firing 110gr Pro-Hunter bullets. That 11.24 mil change resets the zero to 542 yards.
With this zero the bullet hits 5.3" high at 100 yards and 6.75" high at 200 yards.
A 100 yard zero makes the long range setting about 440 yards. At 200 the bullet hits 3.83" low and 15.84" low at 200 yards.
I think that the 300 yard zero is actually more useful!
