Skeleton sniper farming

[Gallvanos]

I've been trying to get the rifle scope for some time in a dungeon, but, I've only seen two snipers in about an hour. I know that they're rare, but I was wondering if there was a more efficient method of farming them (until then, I stayed near a water candle and drank battle potions, with enough room so that enemies may spawn off screen).
Thanks in advance.

Different enemies spawn in different wall types: http://terraria.gamepedia.com/Dungeon#Hardmode_post-Plantera_Dungeon

I do know that, and I've been staying near the wall it spawns in. But, as I said, there's barely any.

I recommend making an area in the dungeon that forces the enemies to spawn in one, certain place. I don't know how well can I describe that, I hope you will understand:
Example: fill all the corridors around you (I'm not sure about the numbers, how far can enemies spawn) with blocks so enemies can't spawn there, mine a hole a few blocks wide, make a platform, then dig a bit bigger room below you that you can't see the floor of it, so enemies can spawn there. I know I described it a bit horribly, but I think there are guides in the Internet how you can make a good dungeon farm. Because the problem with your farming strategy might be that the snipers you were looking for were spawning in the corridors somewhere else, and they were despawning then because you were moving somewhere else or they just walked out.

I'll see what I can do, as the space with the correct walls is small, but I'll try blocking off nearby corridors. Thanks!
