For awhile I've been at a loss as to why people seem to use 00 or even 000 buckshot for their defensive shotguns. I understand these rounds may be better suited for longer shots outdoors since their larger mass will retain energy longer.
However, for indoor defense why aren't No. 1 and No. 4 buckshot used more? Mrgunsngear tests some No. 4 buckshot that penetrates mostly between 12''-15''. Wouldn't this be ideal for a handgun bullet? Why do those using shotguns seem to want to use 00 when it would be considered an over-penetrator in the handgun world?
