Urban Myth. Birdshot at close range is like a slug. It will handily penetrate sheetrock like it isn't there.
Methinks anything coming out of a shotgun at close range will do the job. It's the follow-up shot to the head at close range that closes the deal.
I've taken down Staffordshire Terriers with a wrist-rocket and fishing weights (former paper-boy in a bad neighborhood).
