Improper performance.
I would use any shell except steel shot shells in your 1961 vintage browning shotgun.I would check to see if your chamber is for 2 3/4in shells,or for 3in.shells.Other than that I would use whatever shell fits the game that you expect to hunt.
Steel or lead pellets... you know, the stuff they already come loaded with.
Physically aggressive behavior.
You would use f1 450 12 gauge shells
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.
Depending on condition and wether or not it has shell ejectors the value would be betwenn $500-$2600.
The same as is it was fired from a gun, except the explosion would be broader.
yes but why would you want to do such a cruel thing
Eight valence electrons would complete the out shell. If the outer shell was complete it would still be called the same thing, however the charges would be different.
Cut off the top of the shell, remove the shot and the wad, then pour out the powder. Though, I don't know why you would want to.
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!!!
