What's your farthest shot with a .22 in a hunting situation?

I have a Ruger 10/22 and I have it sighted in at 100yards. it shoots about 2" high at 50 yards. I was just wondering how far other people on this forum can shoot their .22 effectively.

My farthest kill shot was at 50 yards on a rabbit with iron sights.

Also, does someone know where I can find a ballistics chart for .22?
