the swedish sights are fine. They are not as good for battle as other, but for taget shooting in good light conditions, they are good enough.
We're talking about Camp Perry here, where the winners are year after year : M96 followed by K31.
Shooting tips:
Shooting bull target : make sure the bull is a bull, not a dot.
Respect natural point of aim and stable shooting positions.
<< PM me for details on the video, as hotlinking isn't right>>
get a good rest for your rifle.
don't drink coffee that morning.....
sight picture.... and on the bull... shoot all : front sight touching the circle, with a line under, and flat tire. Some shoot center of mass, but is arder to do for a beginner.
You can also try squares rather than bull target. There are plenty o the web to download.
Ammo. The ammo Swedes issued is still some of the best. It runs for 25-30$ per box, but then again, you'll know what you have. Prvi Partizan is not bad, but not outstanding either.
