If it suits some ones needs, sure why not. I carried/shot Underwoods 125gr +P gold dots for quite some time and they are as stout, if not more so, than the BB 158gr. Btw, I was using them in my S&W 637 which is currently at S&W being destroyed due to a broken stud.
When I get my replacement (which in fact is a), I won't be shooting nearly as many super stout loads out of it. I'd like this one to last.
