I don't have any experience with the bayou bullets but you could do some penetration testing into various media to see how they perform. I'm also using the MBW 200 grain WFN-GC. I don't think it is too much bullet for anything. Granted, I live in Alaska and may have different woods defense needs than most folks but I've never heard anyone say they shot their black bear (or grizzly/brown bear) in defense of life or property with "too big" a bullet.
