I just fired about 50 rounds through my buddy's Nagant a couple of days ago. Clay pigeons (4" clay discs) at 80 yards were easy targets with the iron sights. One shot and they were obliterated... They are cheap rifles, and the surplus ammo is also cheap. Easy to maintain but you have to get a good one out of the box first! My friend went through a couple of them before he got one with a good looking bore. The bores are almost always rusted or pitted in some way or another because the milsurp ammo is corrosive, and the bore must be washed with either soap & water or an ammonia based cleaner to deactivate the corrosive salts that have been fired down the barrel.
All in all it is a fun shooter, but a bit expensive to order ammo for. If you're looking to get into target work, might I suggest something a bit cheaper and easier platform to get into? The Savage 93R17 (.17 HMR bolt action) is a rimfire, cheap rifle, and the .17 HMR around here isn't being bought at least. Nobody has them because nobody finds them useful until they see how accurate they are... Just a suggestion!
