I am a little late on this subject. But You should remember that a 22 caliber rifle bullet can and will travel a mile. And it can and will richochet off of the water, rock or stump. I would op for the 22 caliber air rifle, if you are trying to be quiet about it. Most are single shot, but some have multiple shot capacity, I would invest in one of these for snakes. My neighbor uses a 22 cal. rifle for his snake problem I can always tell when he misses !!!! Just a thought since you may never know where that bullet may land , or wish you never knew. But just in case the 22 rifle is still desired , they do make a 22 cal. snake shot for this gun, it works in pistol or rifle. I have some snake shot for my 357 pistol. And if noise is not a problem a 410 shotgun makes a better weapon to hit a moving target. It has less richochet and distance problems.
