Barrel Break-In

Would there be a difference in break-in requirements between a run of the mill target rifle, say a Remington 700 SPS and say, an Accuracy International rifle?
Would the Remington need it and the AI not?

My AW user manual describes the following. They don't make it sound like it is overly important as their barrels are very well finished at their shop. I bought it new, cleaned after the first 5 and then said screw it. 2000 rounds through her now still shoots lights out and does not build up copper.

Good answer.
My AT manual says somewhat differently.
Paragraph two has been deleted!
That says a lot to me.
The two 5 round groups and the thorough cleaning at the factory are enough for me. Just shooting it.
 
Why does this sound like a SNL/AirFarce skid.

Do we follow the break in procedure to a T? YES SIR
Do we look at the resulting patch for self determination on further cleaning? NO SIR
Is break in cleaning a waste of time? NO SIR.

Dismiss. <FlameSuitON :)>

'But believe what and who you want'... 'yes myth'.

Dude, in professional militaries, for maintenance of equipment including weapons, we follow guidelines set forth at command level, which are adhered to to ensure quality of maintenance and modification of such equipment, where the 'running in' of barrels in specific weapons is required. There's no myth about that.

McMillan has an opinion, which is not followed by those far above my paygrade, who are indeed the 'Einsteins' of mechanical engineering, who write policy based on more than one man's view.

As for my experience, I've been an armourer longer than you've been alive. I see according to your profile, you strictly shoot as a hobby, I did it for a living.

But thanks for your input anyways.

Me, I just follow maintenance procedures prescribed for the type of weapon I was working on. If that written policy states when rebuilding sniper rifles, with a new barrel replacement, to fire 5 rds of 7.62mm ball, clean using bore solvent, and repeat for a total of 50 rds, I do that, for as a professional soldier, I am entrusted to do so. It's my name that goes on the serviceable tag, and electronically on file should something nasty happen later on in the service life of the rifle. None of us would ever short-cut policy, when other's lives matter down the road. If some one else has a better idea, based on fact, the onus is on them to forward this information on for further investigation, which may lead a policy change, but until then, policy must be followed. To have some clown (Mike) seem to call me out for something he has only read about... well, that answers pretty much why after 11 yrs on this site, I rarely post and only observe. :). Cheers.

Well, it's clear to me.
AR type rifles, of course not.
Run-of-the-mill target rifles might benefit. Did someone not find shavings?
Rifles with high-end hand lapped barrels, better to not break-in.

SNL? Airfarce Skid? Ya lost me there.

I did spend a few years in base level of repairs and re-builds on a variety of small arms :). It was a most extreme rigid and anal place to be posted to. That was part of my Army career progression. Sorry if you don't like following procedures, and though I may not agree with some of them, they are still there to follow, like it or not.

Thanks.

it's been over 20 yrs since I watched SNL, and I never paid any attention to the dreaded CBC ref the latter.

OP's question is "a break in procedure. I was wondering, if it is really necessary or just a myth? "

Your classic army answer in BOLD. aka Don't ASK.

Why the cheap shot?

My classic 'army answer' eh. What is it your trying to say here?

I reckon whatever floats you boat there Burnaby, you wanna be an army hater, or one of those anti-authority FTW types, that's entirely up to you, met many along my travels, no biggie.

You'd think though, with the amount of posts you have on here, you'd be much more responsible in your response, and having a vast amount of posts does not give you license to be disrespectful to others just because you can. I may have been a mbr here for 11 yrs, and it's people with your attitude is why I remain on the side, observing rather than post.

I wonder if you'd be such a mouthpiece in person.

My initial response to the OP was this "These aren't fancy sniper rifles which need to be run in. . If your AR is 'mil-spec' grade with chrome bore, etc, just shoot as per normal routine. I've never heard of a 'break-in' period for an AR platform. Clean/maintain afterwards as you would after any range time."

Ref AR's, I'd just remove that silly cardboard tube form the bore, clean and get to the range.
