For all intents and purposes, no.
Appearance and measurement of the throat of the barrel, using a wear guage.
It is not measured in years, but in terms of rounds fired. Parts of the rifle are measured, and replaced as they wear out. A barrel, when properly cared for, may have a life cycle as high as 50,000 rounds.
No because the barrel is made for that specific caliber and will not wear out the barrel.
Girls wear buttie shots and boots because they think it looks good on them.
Dont Know but gun shop by my house has one for $100.00 used condition. scratches and some wear on barrel....

Usually, yes. A longer gun barrel allows the bullet to accelerate longer and thus increases its velocity. But it is a complicated problem. A short barrel and a large powder load has about the same velocity as a smaller load and a longer barrel. A longer barrel suffers more wear. Really big naval guns were good for a limited number of shots and each shot was numbered, being bigger for every shot.

If you are going to a barrel race just to watch then you can pretty much wear anything. But if you are going to ride in a barrel race your choices are pretty limited! Most barrel races have a certin outfit you have to wear or you will be instantly disqualified. To most barrel races you have to wear jeans, boots, a button up shirt, a hat (hats can range from many different things, some people wear cowboy hats, some wear helmets, and some even wear helmets that look like cowboy hats), a belt, and that is about it.
Assuming you are not shooting ammo with corrosive primers, a rifle should be cleaned prior to prolonged storage, or when accuracy or reliability drops off. Most modern rifles are cleaned too much, which can wear the rifling. A .22 rimfire probably needs cleaning after 1000 rounds. A centerfire rifle, 500 rounds.
