Looking for advice on breaking in a new 20-inch HBAR barrel, not chrome lined.
I've read several different methods, from shoot-once, clean (do this 20 times), to shoot-once, clean; shoot-twice, clean; shoot-three times, clean; to "don't worry about, just shoot 200 rounds."
Any experience in this area would be helpful.
Thanks.
I used to do all of that then realized I was just wasting time and cleaning supplies! Just take it out, shoot a match, bring it home, clean it and youre done breaking it in.

For a match rifle, I still do the 1-shot/clean routine for the first 10 rounds, then 2 shots/clean. Guess I'm a little superstitious, and I don't know if it helps the accuracy or not, but they sure are easy to clean after 20 rounds. Besides, I'm usually sighting in or testing loads then anyway. Time at the range is never wasted ;-). I follow manufacturer's advice for breaking in a new vehicle, too; what does your barrel manufacturer say?
Got the barrel from DEZ arms some time ago, spent my time getting all the parts and pieces for the complete AR (lower is new DPMS). I'll finally have some time later this month to spend my time with the rifle, testing it and making sure everything works. This is my first build, so I'm slowly feeling my way.
Appreciate the help.
Read a nice piece by a old barrel maker an his story goes like this. He helped a young barrel maker get started and later he ordered a barrel from this guy and in the wrap was instructions on breaking in his barrel. The old guy gets on the phone and says hey whats up with this, an the young guy says look I only sell so many barrels a year so if I get the folks that burn thur 3000 rds and want to rebarrel thier bench gun ,then I just got them to use up 200 or more rounds, then switch over comes quicker. So you think if it was so good why didn't it happen 60 years ago Mmmmmm. Planned obsolescents !
It says normal maintenance is to clean after 25 to 30 rounds. I guess you're supposed to stop during a service rifle competition and clean your barrel :dunno:Quote:

I think Krieger barrels have instructions. Try looking at their web site.

When I bought my WOA upper, I asked John about break in procedures for the barrel. He said shoot it.............
There seems to be two different procedures.
If you have a chromed barrel, there doesn't seem to be any break-in period.
If you have a non-chromed barrel, it appears that the shoot/clean cycle will result in a more accurate barrel, although it isn't clear how many times you have to cycle through the shoot/clean cycle.
Appreciate all the thoughts. I will try the shoot once/clean cycle for the first 10 shots, then shoot three/clean, then shoot five/clean. Part of the cleaning cycle will be to make sure the copper is remove as much as possible.
I'll see if this makes any difference, as I also have a new chromed-bore barrel to try as well. Should be interesting to see if there are any differences.
John @ WOA is what I've done, and I guess the AMU cleans their guns at about 250 rds. I switched to this proceedure and accuracy remains constant. Butches bore shine and a MINIMUM of brush work.
