Default Barrel life

What burns out a barrel faster? Is it higher pressure? Higher speed? Bullet weight?

I have also wondered this but I don't know.
Also what happens if you wear out a gun?

The throat of the barrel gets eroded from the high pressure gases/flame produced when a cartridge is fired.Depending on the caliber and powder charges used,will tend to have a major bearing on how long a barrel will last.
In general,most barrels will last a lifetime for a person that hunts or casually shoots their guns.A person that shoots competition might go thru several barrels a year,depending on how often they shoot,the particular caliber,and how hot they load their ammo.

I have friends that have become "Speed Freaks",and they burn through barrels a lot faster than guy's that load for the most accurate loads.Faster doesn't mean more accurate,but you can't tell them that.

Moderate loads, lead bullets, barrel will last longer than you will. SCREAMING hi velocity, jacketed bullets, some will lose accuracy at 1000 rounds.

What happens when you wear a gun out? You get a slingshot.

You rebuild it, of course. Some folks that shoot at little TINY targets WAY out there demand a much higher degree of accuracy than a plinker or hunter- barrel life for them can be a few hundred rounds.

Powder charge in relation to bore size seems to have the most effect. "overbore" cartridges like the 220 Swift that have a bunch of powder and a small bore size seem to suffer the most. Strangely the .25-06 is not known for burning throats.

Shotguns operate in an entirely different pressure range than rifles- and do not have the ultra high temps at the forcing cone that a rifle has at the leade.

You have a first quality, well built shotgun (for around $2200, it damed well BETTER be!) I doubt that you will EVER wear out the barrels. At some point the lockup may start to get loose, and need the attention of a gunsmith, but with low energy clays/trap loads, that could be a LONG way off.

It used to be a problem with older guns, but better metals are used now. That Beretta will likely outlast you.

Not to pick a fight here, I'm just a little sensitive with one of my favorite cartridges.

To quote the Hornady Handbook of Cartridge Reloading, 8th Edition, page 212, "Because of bad publicity as a barrel burner, the popularity of the cartridge gradually faded. The ill-fame stemmed mainly from the extreme pressures at which it originally operated. Modern barrel steel and newer cleaning techniques have substantially improved barrel life. Also, with loads reduced slightly (c. 100 fps), case and barrel life compare to any cartridge of equivalent powder capacity."

A great example of an overbore cartridge is any WSM or WSSM. if you have them same hornady manual I quoted before, see what it says about a .223 WSSM.

Long slender powder columns (like the 25-06, or the 300 H&H Mag) aren't nearly as hard on barrels as short fat powder columns (like a RSAUM, WSM, or WSSM). I can explain the physics, if you really wanna know, but that much typing on a iPhone sucks. Just don't get the barrel too hot and it should last long enough for an average shooter.

I agree it is mostly reputation. Your mileage may vary. Modern steels and reasonable loads will certainly extend the life of a barrel. Many people get rifles chambered in hyper speed cartridges like the .220 Swift or .264 Win Mag and want to shoot as fast as possible. The pressures and heat involved in pushing a bullet to nearly 4000 fps (or beyond) then shooting over and over will certainly test the mettle of the metal.
