Cutting Shotgun Barrels

[Midnitemo]

no 4 buck is not readily available of the shelf here but I do have a couple of boxes of AAA in the cabinet which I have used for fox control in the past... just thinking about getting a load that covers all bases , a general purpose load of sorts , thinking AAA or BB perhaps....00 buck is a great load but overkill in some circumstances with a fair chance of not connecting at all with a smaller target....thoughts?......have stocked up on 30 and 32 gram no5 and no6 as my hunting cartridge.....I guess I'm looking for a cartridge with the widest application possible.
