Agree - but clean before the first shot to get anything out that ended up in the barrel during manufacturing - like fine metal dust and oil.

Hey SF,  manufacturers instructions are,
For the first 5 shots clean after each shot, For the next 50 shots clean after every 10 shots, Then for subsequent shots clean as you would clean normally.

I've never worried about barrel break-in. I'm more worried about finding the ammo the gun likes. It's amazing the differences you get between ammo and guns, some guns like cheap stuff, others like expensive stuff. Taking the time to figure out which ammo your gun likes is a better thing to do imho.

Go with what the factory says , Different manufacturers use different steel , different boring and rifling techniques and may or may not lap the bore, with different tolerances  different heat treating . Most blued barrels are blued on the inside as well as the outside , you just cant see it , and may need more breaking in than stainless.
Be careful cleaning the bore , use a stainless one piece rod and quality bore cleaners , there are a lot on the market .
Use a bore guide and make sure the rod is centered in the bore and never touches the sides .
dont let the barrel get too hot to touch .
Will it make a difference ?With barrels costing the factory from a few dollars to hundreds and as each barrel is an individual I believe it is better to be safe than sorry .
  

Shooting is the most fun you can legally have with your clothes on .

The lazy do not roast any game, but the diligent feed on the riches of the hunt.

I'd be inclined to follow the instructions, there's a lot of talk about whether it's worth the bother - but where's the harm in doing it.

I did with my gun - wiped with Hoppes between shots and after 3000+ rounds have never seen a hint of copper fouling.

And edit ........

And as for wearing your barrel out doing it, what a lot of hogwash, you'll be shooting those rounds out of it anyway - sighting it in, and I think Micky's already said that.

After further investigation the manual and the makers website kind of contradict each other. Owell, I'm gonna break it in anyway just to be safe,  but will buy several different brands of ammo and see what it likes  Smiley

Ive done it as described and also just sighted in and gone hunting and have not noticed any difference in performance personally. I do clean my barrel/barrels after every shot or sighting in period at the range though. Probably dosnt do any harm though. My 2cents
  

Every hunt is successful, pulling the trigger is a bonus;)

All these different ideas make you wonder about the guarantee's from different manufacturers about shooting under a moa from the factory...

Do those manufacturers break the barrel in before it leaves the factory ??

i was told by a decent gunsmith, that breaking a barrel in, was essentially just smoothing the rough spots off the edges of the rifling lands, to help settle the barrel in..

my 2c worth..  Shocked
  

there is always plenty of time for procrastination.

This is essentially correct. Another term used is burnishing. Fire, clean, fire, clean. The bullet is smoothing things off, in laymen terms.
I once bought a Rem Model 7 that had been shot a lot but I doubt had been cleaned properly from new as it was a copper mine. Took ages to clean out and I basically had to start from scratch as if new to slow the copper fouling down.

Personally I think its a myth perpetrated by barrel makers, it also depends on the type of rifle you are taking about. A cheap 7-800 doller retail barrel is most likely $20-50 manufacturers cost and finished very quickly / mimal care taken so It may have some truth on cheap factory barrels where the finish can be a bit rough to say the least but from personal experience properly finished/lapped custom barrels neither need to be or should be. Why would you waste some of the barrel life essentially for................ nothing.
A good custom barrel costs upwards of a $1000 fitted and chambered and if its in a magnum calibre the first 1000 rounds are most likely the most accurate so why wast some of them.
I have currently a Rock Creek barrel on my .223 , Shilen on my 6.5SAUM and a Trueflite Ultra Match on my 375WSM all are easy cleaning and shoot well but the Rock Creek and Shilen shoot significantly better than the True flight.
  

I have English Pointers because they don't ever grow up either..

You would think you wouldn't need to break in a custom barrel, but my Trueflite Ultramatch in 7mm mag copper fouled like crazy from new. It eventually settled down after a few hundred shots down it.
At the start it took 24hrs of regular patching and soaking overnight with Boretech Eliminator to remove the copper from one shot.
