Yes your Winchester model 1897 pump action shotgun can shoot buck shot through it.
Yes. It sure can.
Depends on when it was made. Go to Browning.com and ask.
A shotgun can shoot up to 80 yards it it depends on what the choke is on the gun.
Ensure you look at the stamped shell gauge on the side of the receiver (12 or 20 Gauge). Should be able to take 2 3/4" and 3" shells.
