New Rifle -What you do before use

[longrange]

Clean following cleaner instruction and send. I “broke in” my AI barrel but that’s because I’m OCD. Not required

According to a very well known (in Canada) long range rifle shooter I have had conversations with, he said their rifle team did this and it kept the rifles ability to shoot well before foulings - in other words - you could shoot a match of 50-100 rds without needing to clean the rifle until you were done.

Shoot 1 shot and clean, shoot 2 shots and clean, 5 shout and clean, 10 shots and clean, 20 shots and clean.
You should now have broken in the rifle well enough. You will know when you clean it

By "clean" it means - run 2 wet solvent patches then follow up with a copper cutter solvent, then a dry patch to get the solvent out.

Personally I would never run a brass brush down any rifle or pistol. Just wet and dry patches

You have obviously never seen some of the gun we see a patch would be lucky to knock out the spiders

 

[BSAMarty]

I was referring to cleaning a new rifle, not a new to me (used) rifle.
Still would not use brass brush though.

 

[User00057]

surely breaking in a barrel is pointless considering it will of just been shot when proofed. Surly if it was to detriment the damage will have been done when proofed ?
Not sure but I thought all rifles are shot while in factory still

Give it a good clean and then put the bore scope down it again. If those "cracks" are still there I'd take it back to the dealer with your bore scope in hand.

Getting sent back, supplier request, think they are not happy either

Good stuff. It looks total pants to me so great to see you're getting some traction via the supplier.

Keep us updated, please.

Will do

So were the "cracks" still evident (same location and shape) after a good clean?

 

[Mungo]

Those really weren’t cracks! At least, not what was in the first set of pictures. Very clearly bits of thread.

 

[Brave Echo Niner]

How did it shoot would be my No. 1 concern!

Borescopes are useful, but I would have at least tried to see if it was shooting well!

 

[doigan]

It was the roughness at throat area and poor condition, it would not chamber new ammo, bolt was very tight to close and bullet heads were getting scratched even tried making the rounds very short

 

[Utectok]

99% of barrels I’ve borescoped look horrible but shoot fine.

As I say couldn't even get it to chamber using brand new Lapua brass and short rounds

Ah yes, now I can view the pictures on a proper monitor rather than my phone those do look like threads.

Would never have passed proof if the headspace was that poor.

 

[doigan]

No idea, but could only close bolt if forced, COAL is 2.217 I made it 2.2 and still wouldn't close. Only close with case only.

I was recently looking into this for a Barrett Fieldcraft I picked up.
If Barrett aren’t recommending anything other than check for obstructions and using it, that’s good enough for me.

But then again, Proof Research recommend the below, but stress not to over think it:

 

[doigan]

Just watched an article last night, they quoted Tikka/Sako informed them that cold forged barrels do not need broken in, this is to do with the manufacturering process. Might be why I couldn't see anything in the manual

 

[HonestJohn]

Still would not use brass brush though.

You’ll be doing more harm ‘not’ using one by leaving fouling and deposits not picked up by patches
