I have had SKS's from China,Russia and Yugoslavia.In my estimation the 59/66 is the best of the lot.You have a fine shooting and well made rifle.
They shoot great out to 150 yards with iron sights and are really good deer rifles.
Take it from one who has tried everything.Don't attempt to put a scope on it unless you use the Choate which requires drilling and tapping and a little stock inletting.The others are not worth the time and effort.
You can get some 154 grain soft point hunting ammunition for this rifle made by Wolf which works great.
