Sort of correct.No, it wasn't supposed to be for 762 x 39. The 762 x 39 scope reticle only ranges up to 400m.
I suppose in the rush to sell stuff, some dealers may come up with ways to use scopes designed for 762 x 54 rounds for the 762 x 39 !
The ranging icon for the x39 round is only up to 400 meters is true. Although the chevron's are only for 100, 200 & 300 meters as shown below;

Contact TeaPot2 for any POSP scope questions as he retails them.
Now as for the reticale that you are using. That one is designed for the x54R round and yes the range finder start's at 200 meters and works out to 1km for a man sized target. Also the chevron's are only for 200, 400, 600, 800 & 1KM BDC for that round. This 1's do not line up with the x39 round at all.
