Jeffhasapond, the Crossman 760 I was shot with had velocity of approximatley 700 fps at 10 pumps, it had been pumped up 16 times just before I got shot, yep, that's 6 more pumps than recommended. I am pretty sure it was pushing 1000 fps when I got hit in the finger.
The other thing is that I have spent some plinking time shooting at 1-2" BG with .22 handgun at the pond, even with a .22 the water slows the bullet down significatly before getting to the fish. I have doubt you could kill a CC or GC with a .22 if they are more than 6" under the surface.
