What Karl's post shows on the forums is the overwhelming and vast majority of shooters see the 375 as the start if the big bores.
Forum owners can structure things however
they like for their own reasons.
Post a question like:
"
Do you consider the .375 cal a big bore?"
on a forum that often deals with the topic
of DG, Africa and associated rifles, and see
what kind of responses you actually receive.
You may just come out a little disappointed .
