I hope I am not digging up too old of a post here...
There is a great reference book that was translated by maj Gebhardt that you can get from Amazon:
http://www.amazon.com/Official-Sovie...1363469&sr=8-1
This is a translation of the Soviet MOD manual and its pretty good on how to run this weapon... not on sniping.
Next question... since not all 7.62x54R ammo is created equal... and some is better for this rifle than other...whereas others are just usless, What kind of ammo do you have? Confirmed Soviet 7.62x54R?
Reason I ask... is that some of the Russian stuff will allow you to have more than reasonable groups with the SVD... where as the Chinese stuff is useless. You would be better served throwing it at your target.
Hope this helps.
