The CCI .22 bird shot patterns very well for the distance required to shoot a coiled up rattle snake. I use a S&W 317 and keep the first three chambers loaded with the bird shot and the remaining five with hollow points.
Shot a fox in the butt with the bird shot at 10 yards or so because he was waiting for my puppy to come outside.
Not too good on the fox, he was back the next day. Hollow points worked fine.
