    I recently aquired a Mid '80's Dragunov / PSL I recently aquired a Mid '80's Dragunov / PSL Romanian built .762x54R "Sniper Rifle"
    I have quoted that classification because I realize it is not a true sniper rifle by today's standards, but it was on my bucket list and in it's day it was a very capable and deadly tool on the war front. I am also somewhat into military history. Anyway, I am looking for help with bullet drop math relating to the PS-01 scope which is a serialized matched to the rifle. If any of you out there are familiar with this scope please help. I know all of the ranging lines and relating bullet drop chevrons are in meters. I have zeroed the rifle @ 100 meters using Wolf Gold 150gr fmj ammo. I thought this round should be a close match to the round the scope was calibrated for. Benched and baged it groups .85" @ 100 meters. Using the chevrons on the glass @ 200 meters it groups 3.25 " however it is about 5" high and 1" right. A t 400 meters groups avg 6.5" and 8" high and 3" right. Using the math of 1 moa per 100 yards at 400 yards I should come up about 8 moa from zero. When I do it this way I cut my high hit ratio in half. I don't know, the water is getting muddy in my head,- meters, yards, Ft/s, minutes are minutes anywhere, right? Any Help ??? Also do you think the right from center is spin drift?

    No. most likely the projectile the scope is designed for didnt quite have as high a ballsitic coefficient as the modern stuff youre using. Grab a case of anti personnel milsurp of the same vintage as your rifle and I bet your aiming marks will correspond at thier respective distances. You could also research the ammo its designed to be calibrated for and try to duplicate it with handloads.

    I'll try your idea thanks JLA. Also found a little more info on design. Scope is slightly offset to side which was thought necessary during design to facilitate loading with stripper clips. This was later found unnecessary due to the final design using a detachable magazine. however the optics and mounts were already being produced. windage will have to be adjusted for shots over 100 meters.
