I am not familiar with the 22 "bird shot" that uses pellets, I guess I am too old school. The 22 "bird shot" I use is the brass case with a crimped end and it shoots small pieces of lead shavings. It does do the job on snakes and puts out a large enough pattern that it usually does the job with one shot. I would think that pellets would no be a great choice, particularly in a 22.

No the crimped 22 shell you are familiar with holds 25 grains of #12 shot----- Bird Shot.
