Here's the problem with your question sir: hubris. The majority of the opinions requiring a big bore rifle are thinly veiled justification for whatever pet caliber the particular individual is fielding. Some say "the client" and the is expectoration is audible with the last syllable as surely as "doesn't need a stopping rifle" will follow. Shoot the largest rifle you can handle well and enjoy yourself without regard for the opinions of others. Pursue the caliber that speaks to you and direct it well.
