This is a discussion on How Many Rounds Before an AK-47 Barrel Is Shot? within the Foreign forums, part of the Gun Forum category; I am curious as to how many rounds a Hungarian AK-47 barrel can take with normal semi-automatic fire before the rifling burns out?
Just wondering ...
Better question is how much prolonged bump firing can an AK barrel take? Mine has seen its share (quite a few 700 round days, lots of burned wood) and will still put about 4" groups at 100 with optics.
I remember reading someplace, can't remember where, that the Russians usually never replaced barrels on AK's. They said the barrels were good for the life of the reciever which, IIRC, was 80k-100k rds. That is for the stamped AKM variant though. I'd think the milled recievers might last longer. However, the Russians were not all that concerned about accuracy.
I wouldn't worry about replacing an AK bbl unless it won't keep all its shots in a 8" group at 100 yds. Some AK's shoot like that when new, though,lol. Most AK's should average anywhere between 3-6 inch groups at 100 yds.
ETA: Maybe an 8" group is too strict a standard though. I think you should deceide when it is not accurate enough for you, and then replace the bbl if you want ;)
That might tighten up the groups a little, I know the bores are a little larger than usual .30 barrels.
7.62X39mm ammo uses a projectile that is a little larger than normal .308 rounds anyway. Soviet block calibers... 7.62X39mm... 7.62X54R... 7.62 Makarov... ect. use a .310 caliber bullet. If you use american made 7.62X39mm ammo... its going to be .3080... that is best used in an american made barrel in 7.62X39mm caliber like a Mini-30.
If you have an AK or SKS... use foriegn made 7.62X39mm ammo for best results. I have a Romanian GP WASR 10... the one with the bayonet lug and the half moon slant break. So far i have put right around 23,000 rounds through it and when the barrel is clean and is cool to the touch i can put down a 3 inch 10 shot group at 100 yards with good ammo and careful aim.
The best foriegn made 7.62X39mm ammo i can find is the Cheeta ammo from South Africa. It is well made, uses a brass casing (brass casings are good for long chamber life) and the most accurate foriegn 7.62X39mm ammo i have found. Oh yea... its real cheap too! :D

Might be best not to clean it too much so that the built up copper and carbon deposits can help protect the lands and grooves in your barrel. That way the barrel last lots longer.
Oh yes... might i add... the reason most AK's dont shoot worth a damn is because people dont take care of the them. You put tens of thousands of rounds through ANY rifle and dont take care of it... its not going to shoot good.
