Then why... never mind, I could ask the question, but I won't...
It's not the "echo chamber," it's the collective wisdom of the membership... or so we should believe. I think I know what you were saying, but really, on occasion, folks chime in with some actual knowledge, so I'm not gonna complain too much (although, in the words of Joe Walsh, sometimes I still do) about the diversity nor even the bandwagon effect we see in answers to questions posed by OPs.
PS - I think there actually are some hard rules in the shooting world. I tend to stick with 148 grain or 158 grain wadcutters or JHPs, standard pressure in snubbies.
