Basic answer is ~ 4 moa with milsurp ammo for all milsurp rifles.
Some rifles...like Swiss and swedes do half that or less.... easily.
Handloads can shrink that as well.
My swedes are on average 1.5 moa rifles. Some do a little better..my M41 sniper for one and my AG42.
Finn mosins are also good shooters...I have two m28/30s that are <2 moa with handloads.
Some guns are just shot out and won't do anything...
So in short..." It depends"

Apparently, the accuracy standard for the m/28-30 involved the following:
-10 shots fired from a rest by a capable marksman at 300m
-the best 8 shots had to fall within a circle with a 15cm radius measured from the MPI, which would be 3.44 MOA
-at least 4 of those 8 shots had to fall within a circle with a 7.5cm radius measured from the MPI, which would be 1.72 MOA
-if a rifle inspected (4% of rifles were randomly chosen for inspection) could not do the above, it was not accepted for service
Supposedly, the average m/39 inspected was slightly more accurate than the average m/28-30 when tested to the same standards.
I'm not a good enough shot to be able to shoot up to my m/39, yet. At 500m a couple of months ago, my 20-shot group was 5.74 MOA extreme spread, 3.76 MOA mean radius. The rifle is almost on for windage, though. MPI was only a little over 2" to the right of my POA in that plane at 500m.
