You know I think you are awesome, but, I have to disagree with both your assessment of snakes, and pump shotguns.
Snakes eat frogs, that's their nature. If you were able to save the frog then the snake was non venomous. Snakes will do more to prevent mice and rats in your house than a whole clouder of cats.( yes that is what a large group is called)
I have only killed one snake around my house, a copperhead that had bitten my dog for the second time in two weeks.
Mrs. Jusme has the same,attitude as you about snakes as demonstrated by my posts in this thread.

Now for pump shotguns, I taught my daughter and her best friend how to shoot one, and that's what my daughter keeps in her house for HD. My daughter is 5ft 3 her friend is 4ft 11. I started them with bird shot and worked up to 3" magnum 00 buck. This was a Mossberg 500 with an 18.5" barrel. It is all in proper shouldering and stance. My wife is also very proficient with it. For reference I am 5'-8" 165 lbs. I can empty a full magazine (6 rounds) in under 8 seconds.
Please think about relocating snakes rather than killing them, they mean you no harm, and only go where they have a food source. JMHO
