Shotguns

That all depends on the shotguns overall condition,and bore condition also.

depends on condition- $400-$750

Improved cylinder

Westernfield was a brand name used on guns sold by Montgomery Ward stores- and made by gun makers such as Remington, Mossberg, High Standard, etc. We cannot tell the model from a serial number, and cannot tell the age except in general terms.

They range from 80 in bad shooting shape to over 300

The "crown" of any firearm is the front end of the barrel- the muzzle. It refers to a rounded shape of the end of the barrel.

Depends on model and condition. Typically $100-$150.

In most states, yes (check YOUR state game laws through the game commission website) HOWEVER- I would not recommend it. The load of shot, or the energy of a .410 slug, is simply too small to reliably and cleanly kill a deer. It is more likely to wound a deer that will die in a day or two.

These were made many years ago, and may not HAVE a serial number. Serial numbers were not required by law on rifles and shotguns until 1968. Yes, it is perfectly legal to own a firearm that never HAD a serial number IF the law did not require it at the time the gun was made. It is illegal to remove any serial number from a firearm, or to possess one that has had the SN removed.

The bore refers to the hole in the gun barrel thru which the projectile (bullet) passes. Some guns have a smooth bore, but many modern guns, both pistols and especially rifles, have a rifled bore, that is, the bore has a helical (spiral) groove that causes the projectile to spin as it flies thru the air. The diameter of the gun's bore determines the size of the bullet or shell (e.g. .22, .45, 9mm, etc.)

You dont, you keep it on.

Shotguns fire shells with many small pellets- or shot. The shot string is a 3 dimensional view of the shot in flight. When bird hunting with a shotgun, your goal is to have the shot string intersect the bird in flight.

Boito was an inexpensive line of shotguns made in Brazil in the early 1970s. Value is probably in the $150-$175 range, depending on condition. These were typically sold through K-mart, G.C. Murphy department stores, etc.

It's called a choke, and restricts the bore a few hundredths of an inch. Most are round, for hunting, but there are some called "duckbills" that spread the shot laterally for combat purposes, though they're not popular anymore because they didn't offer a significant advantage. There are fixed chokes, permanently part of the barrel. There are adjustable chokes, which turn to constrict. There are removable chokes, which set in place with a wrench.

Yes- that is what the poly-choke is for.

Rifled slugs. Sabot slugs will not be as accurate- hose are meant for rifled barrels.

Unlikely, but contact havlin Sales through their website. They are the "go-to" company for ANYTHING related to Mossberg- and very nice people to deal with.

$50. Safety recall on these. Contact Sears. They will trade you a $50 gift card for the bolt from the gun.

These were built by J. Stevens company for Sears and other stores. They're quite common. Depending on condition, that specific bore and brand typically sell for $250-$400 in 2012.

Depends on your state and how quickly your results come back on your NICS background check.

About $65-$75, depending on condition.
