I'd like to try these out on some jack rabbits

will they adversly affect my 9mm in any way?

thanks for any help

I don't know about the CCI 9mm Shotshell, but I have and do use the Federal .22LR Bird Shot in a revolver, 6 inch barrel. I can tell you it works for snakes at about 6 -8 ft. At 7 yds it scatters and is ineffective. I can imagine a 3-5 inch barreled 9mm being effective at similar ranges, but hardly at a range for rabbits. If you get that close, just grab them and save ammo! <grin> <funnin' ya> It doesn't affect the gun, that I can tell. Maybe someone has used the shotshell and can give ya info from their experience with it.
