Rattler 357 report
I've owned 2 FX Impacts with lots of additional barrels and upgrades over the yrs. I chose the Rattler357 because of the range of projectiles and the power. I do pest control on my farm out here in Hawaii. My pests range from Parakeets to Feral pigs, https://youtu.be/NmJVsXgOm-s https://youtu.be/wFHkNU34Wmw
