How long does a cannon last?

.22Lr cannons ? What are talking about??

I think he's asking about barrel life. Particularly throat erosion, etc.

Either a non english speaker, using Google Translate, or drunk posting.

OP:
Barrel life is affected by a number of variables. Fully automatic fire can destroy a barrel in less than a thousand rounds. High pressure, high velocity cartridges can see reduced accuracy in a couple of thousand rounds. Traditional mid pressure smokeless rounds should have barrel life three times that.
.22lr rifles have basically indefinite barrel.

Yes, the OP is Somewhere in Europe and is apparently using a computer translator.

Radagast covers it pretty well.
A .22 LR will shoot accurately enough for competition 50,000 rounds.
A 7.62 will shoot accurately enough for military use for up to 30,000 rounds (NRA copy of a report from Finland.)
A 5.56 will shoot accurately enough for military use for at least 10,000 rounds (Luckygunner report.)
A .308 will shoot accurately enough for a good conventional target shooter 4500 rounds. (Personal communication from a competitor.)
A .308 will shoot accurately enough for a Master class F-T/R shooter 2500 rounds. (Personal communication from a competitor.)
The Army F-Open team was changing their 6.5x284 barrels at 850 rounds but a civilian who had to pay for his own would keep it until it wore out at 1200-1400. (Comment heard at a shooting match.)

Also, depends on how you define a worn-out barrel.

When you can no longer hold the 10 ring, or when you start to see key-holes.

Further, it depends on the propellant, working pressure, and bullet type. Hot propellants and high pressures don't last as long as cooler propellants and lower pressure.

High performance tank guns with 87,000 psi chamber pressures and 3600 F flame temperatures last about 1500 rounds. Naval guns with 37,000 psi chamber pressures, and 2600 F flame temperatures last about 7000 rounds.

Actually I use a translator, my English is not enough extended. But I assure you that I am not drunk, I come from elsewhere from my shooting club and of course we do not drink.

What I would like to know is the longevity of the guns in 9mm and 38 sp, this for non professional (military ..)

Thank you for your answers

A long time, I wouldn't worry too much about pistol barrels.

Greetings to our sober European friend. Happy Holidays!

Merry Christmas , sounds like you are blessed . You have a gun& are able to legally shoot it. Welcome freind

I'm curious now. How long does a cannon barrel last?

Straight wall casing will last a long time in pistal, where as bottle neck rifle will create a lot of throat erosion depending also on how hot the loads are.

I want to know too


A handgun barrel will withstand tens of thousands of rounds before accuracy diminishes. With proper cleaning of course.

The 16" main battery guns on the North Carolina, South Dakota and Iowa class battleships required replacing or re-lining approximately every 300 rounds. This info came from the official book on the USS North Carolina.

A friend wore out a .38 Special with wadcutters. But it took 150,000 of them.
A 9mm with jacketed bullets will probably last 30,000.

Of course, by that time over 1/2 million lbs. of projectile would have been sent downrange.

I would imagine a 38spl shooting lead at wadcutter speeds will never wear out. I think the action will go long before the barrel. The barrel will probably last hundreds of thousands or rounds. The 9mm using jacketed bullets will last far less, but I dont know how much less. My 1911 in 45 shows zero measureable wear at about 12000 rounds, and my friends cz75 shows zero measurable wear at 15000 rounds, mostly rapid fire too. Ive personally never seen a shot out pistol barrel.

Thank you for your civil response. A true gentleman, Sir.

Sometimes, especially with new or foreign-language writers, one has to read between the lines or gently question them to get at what they mean.

Congrats for your patience. You might add that "OP" stands for "Original Poster," meaning the first poster for this new member.

Ditto on what I said to Radagast, bangswitch. I was going to chime in with "about 250 rounds" for the "cannon" part of the question. I reckon it depends on whether the battleships are trying for 1" (2.54cm) groups or not .

American Revolution cannons are still shootable, as are Civil War cannons.

I am taking modern 5"/54 or the 5"/62.

Battleship guns worked at a higher pressure for range and penetration, also, their life was longer if they only shot HC (lower Vm) not AP.

A 155mm gun/howitzer is good for about 5000. However, there is an applicable muzzle velocity drop over that number of rounds, that must be compensated for in the firing tables. The bore diameter grows about 3mm, and muzzle velocity drops about 2.5%

That's where I got the info I quoted....

The 3"50s, (roughly 76mm, fixed round), on our ship had many rounds through them, barrels were never replaced. Then again, the mounts still had iron spiderweb sights for AA use. No joke. We were WAY low on the priority list for armaments, even during the 600 ship Navy.
I have never worn out a pistol barrel, ever, and I shoot all the time. I also use a lot of home cast lead ammo with powdercoated bullets, so it's not like I'm shooting screamers coated in sandpaper. As long as you treat it right, it will work well for years.
