Depends on choke, distance and end state.
The choke is a way of narrowing the barrel. It is designed to keep the shot in a tighter pattern. A full choke is supposed to increase the effective range of the weapon.
Depending on barrel length, load and choke, anywhere from 10-100 or more yards
yes
The JC Higgins Model 20 was a slide-action shotgun made for Sears by High Standard. Value, depending on condition, can range from $100-$225.
It is possible to fire a shotgun without a choke, but it is highly not reccomended, and they don't cost that much If you select a barrel with no choke (cylinder) it will cause the pattern to be looser than for a barrel of a shotgun that has a tighter choke. The extreme is "full choke" which keeps a tight pattern out to the effective range. Full choke is typically used for waterfowl. A shotgun that is pressed into double duty (shot for small game and slugs for big game) would work well to have modified choke. Slugs have to be designed to fire through a full choke without blowing the barrel but you will certainly shorten the life of the barrel by firing slugs through a choked barrel. If you can afford an extra barrel, then use a cylinder (no choke) for slugs. Remington and other shotgun manufacturers have interchangeable choke tubes (see link) that allow you to screw in the appropriate choke for your quarry.
It's a shotgun, not a rifle. Value for the single-barrel 'Newport' guns in .410 run about $75-$100. sales@countrygunsmith.net

J.C. Higgins model 153.17 shotguns were manufactured in the 1950's, making them approximately 60 years old. The price can range from $50 to $300 depending on the item condition.
The Super choke is adjustable to allow the shooter the ability to shoot with an improved cylinder choke all the way to a full choke. A choke is a reduction in width of the barrel at the muzzle of the shotgun. This affects the rate at which the pellets spread after being fired. An improved cylinder choke is a slight adjustment so that the pellets will spread out like an ice cream cone shape while a full choke sends the pellets out with much less spread. This affects range and accuracy of the shot at various distances. The use is to be able to set the desired choke before taking a shot. A shotgun with a single choke setting cannot be adjusted by the user.
