I have only been hunting a couple of years, but have shot for much longer than that.

I regularly practice off-hand out to 75 yards, then kneeling to 100. If I can maintain a 5 in. group with that I'm satisfied. Naturally when sighting in I'll use a bench or prone, but those aren't normally available when hunting.

My first kill was last year. 110 yds resting against a tree.
