Chrome lined Barrel life
About how many rounds will a chrome lined barrel last before the chrome lining is worn away/accuracy begins to suffer, assuming you use non-corrosive ammunition and the proper cleaning solvents. After how many rounds should the barrel be cleaned?
Just curious to determine the state some used guns are in when the seller states approximatly how many rounds have been fired through them.

i have a pair of TYPE 99 ARISAKA SHORT RIFLEs (late 1939, and early 1941 production)(JAPANESE NAVAL INFANTRY ISSUE) that have chrome lined BBL`s. both guns are well over 60 yrs old, and one can assume that not only have they both been fired alot, and that they saw use under pacific thearter combat conditions. mil spec corrosive ammunition was used...
both guns are a bit beat up, and show heavy use, but the bores are mint, and they shot better than MOA groups at 100 yds.
i think a better question would be how long will the chrome liner last based on who made the gun, and what the level of initial production quality was.
one has to assume that my 99`s were cleaned and maintained under pretty pore conditions with only the most basic military cleaning equipment. both bores are near perfect...
a few random thought...

Hi,
A chrome lined barrel will last longer than any of us if used properly and not fired excessively.

i have put thousands of rounds through my ak's and haven't seen a problem yet. but my grouping has always been a bit loose. i blame me not the gun. it would be interesting to know, great question.

I also have an old type 99 that literally looks like it got jammed up an Elephanys arse, left there a year, taken out and not cleaned! There is likely 3 ounces of glue holding the badly split stock in about 8 places, there is somewhere in the area of 90% rust coverage and the bolt handle is bent back about 3 to 5 degrees by a blow it recieved falling from the rafters of the garage where my friend found it. It is a mid war Kokura gun that is one step short of a last ditch rifle and looks every bit of it. The one shining element to the gun is a mint, sharp, bright and shiny bore. All I have ever done to the gun is clean off the rust, clean the bore normally and stone the trigger/sear and it shoots like a bandit. I am a big believer in the idea that no gun is going to outperform its barrel limitations regardless of the amount of time and care put into the rest of the action etc.
If this gun shot as poorly as it looked, I would not stand within 50 yards of it when it was discharged, but it just does an amazing job. The gun was no doubt subjected to incredible abuse by its' original owner and never faired too well after that due to 50 years of really poor storage. Given all this, I think you get a basic idea of just how durable a chrome lined bore can be.

As with a non-lined bore,..it will still depend on rate of fire. Although the chrome lined bore will take far more rounds,..it will erode at an accelerated rate as the heat builds. I wouldn't plan on shooting any benchrest matches with a chrome lined bore however[;)]
why chase the game when the bullet can get em from here?....

I read a story about a South African AK 47 that had been burried for a number of years. The rifle was very rusted. It was recovered in a crime insident and the rifleing was still good enough when fired that it matched[;)] the bullet to the crime. Best, Robert
