Mines zeroed at 50m and I get 20p sized grouping at that range, in my somewhat limited opinion, .22 fills the void between air rifle and .17hmr.
From what I've read/heard of people's experience, .22 is great for lamping as it's quite and .17hmr for daytime at longer ranges.
Not getting my .17 until my license comes back with it on so only going by what I've heard.
