i would be hard pressed to say that its more accurate than a barrett made rifle..
i have fired Dragunovs before.. which is a terrible rifle to shoot.. kicks like noones business and the ammo is generally rubbish .. the .308 versions are much better
if this KSVD is using a larger calibre round in the same platform, then it will be like being ####-slapped by the devil himself, every time you pull the trigger
EDIT: after doing a small ammount of reading it appears that the KSVD is a type K SVD .. so its the standard dragunov firing the 7.62x54R case ... this rifle sucks to shoot, and is no more accurate than a run of the mill M14. the version you have pictured is the 'Tigr' a shorter, folding stock version for paratroopers.
they have been chambered in 9.3x64 Bernneke .308 and 30-06 for export.
