3 shot (1 in chamber & 2 in the tube)
It is a shotgun shell.
Yes as long as you get one made for the Winchester model 1300 and chambered for the same length of shotgun shell that the receiver is chambered for.
300-325
i dont know. i think it is
I know very little about model 12's but I do have a 16 guage with a 24" barrel chambered for 2 9/16 old paper shell.
3"
the shotgun takes a 2 3/4 shell
Remington makes a model which does.
