Well my friend it's called stretching and you need to work your way up to 12g by stretching the piercing one gauge at a time (30 days between gauges) in order to get to the 12g you want. See a professional body piercer for assistance.
Yes you can get your ears pierced at 12g, just see your local professional body piercer.
Browning.com has manuals you can download for free.
50-100 USD or so

NO!!! A 12 gauge shotgun takes only 12 gauge shells. A 20 gauge shell would fall into the barrel and get stuck about half way to the muzzle. You would be in for a nasty surprise when you put a 12 gauge shell behind it and pulled the trigger!!!
Most likely
Less than $200.
3 Shot only. No removable plug.
rabbit ear refers to the exposed twin "hammers"on a double barrel shotgun. when seen from the rear they resemble a pair of .....thats right... rabbit ears.
it is not safe to fire 16 gauge shell in anything but a 16 gauge.No shells will interchange with other gauge guns since a 16 gauge shell would fit in a 12 gauge chamber, I would think you can do this.
12 gauge wire is used for household plugins, and 14 gauge wire is used for lights. So, 12 gauge is the size to use. But since a freezer has an electric motor, it is best to not plug anything else with a motor into the same circuit.
