What is important, is not to get too little or too much gun for my needs. It's going to be mainly for dispatching predators that I either trap catch overnight, or that I might find in my yard during the day as they free range, which would likely be a dog (hate to do it, but not going to lose chickens if I can help it). One important factor is that I have kids, so until they've learned some respect for guns, wherever I have it kept, it can not be loaded, so likely, I'll have it hanging over a door unloaded, and will need to be able to load it fast. I'm considering getting a 22 semi, so that I can grab the clip on the way to the gun, and slap it in. Thinking it would be faster than bolt action to load.
 
Those are my thoughts so far. What do you think?
