It wont be the same as the momentum of the heavier bullet and BC will affect it, but theory is if you can hit a gong at 1000 metres with a 308, the 400m with a 22 is a similar challenge.

I have pushed a 22LR out to 200 to see and has some success at 150m (I will admit there was some luck involved here as well) but the 22 is capable of hitting things at ocer 500m IF you can work out hold over etc. (From memory hold over for zero at 75m to hit a target at 500 m is something like 50 feet above the target at 500m.....)

Ironically it is apparently easier to get consistency from sub sonic or target ammo, as the 22 going transonic as it slows through the sound barrier causes "wobble".... I saw a youtube video of someone trying this some time back. If I can find it again I will post it.

Yeah I shoot CCI SV or Subs, seems to group nicely. At 120m I can hit my 200mm gong every time without an issue. I normally shoot with a bipod though. At that distance I can sometimes 1...2....3 and the group of bunnies never moves.
