Common sense would say yes, set the site at 100 yards and it should shoot on.

But the Soviets issued one rifle for two men and sent them out that way so how much common sense is available here.

I went up to check mine, they do have a setting for 100 yards/meters, not sure which. But I have not yet shot any of them to know if they shoot on target at 100 yards or not. This does seem to be a common problem as it comes up an awful lot. Most shooters seem to find they shoot high at the 100 yard setting and you can't lower the sights any further to correct it.

Perhaps it is because the sights are in meters, not yards and 100 meters is a bit further than 100 yards, not sure if that is enough to greatly affect the point of impact but it may be an inch or two.
