Better 7N6
Hi PM...
In an SSG-82, groups with Soviet 7N6 have been hovering around 1 3/4".
Pretty good for military ball. Bulgarian has been anything over 2 1/2"
The commercial Barnaul lead-core that was available a few years ago is notably better, with 1 3/8" being typical in that gun. Also, it is non-corrosive, the unlined East German barrel has seen more of that ammo.
Dynamit Nobel (RWS) that came with these guns is sometimes a sub-minute (1") performer, but not reliably.
The gun is action-bedded in glass, and the barrel unsupported. Standard 4x glass, six shot groups at 100 yards from a shooting-bagged rest.
Oddly, the mil-spec Bulgarian '74 builds often seem capable of an honest two-inch group with Soviet 7N6 ammo when shot off of a rest. Izhevsk Design Bureau did their homework well. Bulgarian 7N6 shoots a three to four inch rested group.
Has anyone here tested Soviet 7N10 enough to see how it groups by comparison?
