I hate to dispute your .204-slandering rabbit claim, because I can't prove it's false with mere on-line research. But have lit up a few 8-12 pounds varmints with the .204 and, gee, they flew!
One of my .204's set a state record in Wyoming for how high a prairie dog flies, but it's not valid in Montana because the air is thinner in Wyoming.
No picture, no proof. Who is going to yield first? I don't seeany 204 invading my safe in the near future...
