I am thinking of getting some in 40 S&W for my 610. The weather has caused the grass in a vacant lot I own to grow really fast and I have heard from my neighbor that she has seen snakes coming out from the grass. I intend to mow the lot, but I want to have something just in case one of these hideous, slimy reptiles tries to hitch a ride. Are CCI/Speer shotshells suitable for use in revolvers? Someone on the S&W forum says not to use them as the cases will split. Any truth to this? Thanks.
