I have only managed to hit a coke bottle top @ 55yards with mine, never tryied past that.

I was quite inpresed with my self, hit it within 3 shots, and that was sitting on a tree root with the rifle rested on my knee.

I had mine worked on by Tench/Tweeky, off a bi-pod its pellet on pellet @ 50yards (in the right conditions that is, no wind ect)

Forgot to add mine is .22
