Good post, Dan.
I like the option of using CB loads in my bolt gun. My first successful use with them was (like you) in a Rem 572. Accurate enough for feral...ehem...you know. CBs would be my choice for the occasional crow (my primary pest) except that civilization has grown nearly to my doorstep and I have to be concerned about where the slug ends up in the case of a miss - just as one would be with 22lr. This has forced me to switch to the (noisier) pellet rifle for such shooting, though I would much prefer to use the CBs.
