Tell your gunsmith to do it. Weeds out a lot of em
I don't do it anymore, I used to, but being old it's a waste of time for me. Some barrels can benefit from it, ...I guess, but I could never prove it. Today my custom barrels are already hand lapped, so no barrel break is necessary...IMO.

Its not the barrel lapping that break in takes care of its the chambering process
I know the difference between barrel lapping and barrel break in...so what are you talking about?...The bullet doesn't touch the chamber...the throat area could be polished where the bullet enters the rifling, but that is not barrel break in, in my dictionary... Do you call it chamber break in? In any case I don't do it anymore. And I always inspect my own work with a borescope...after chambering.

You said you dont do barrel break in because your barrels are lapped. Barrel break in has nothing to do with barrel lapping its the chambering process that needs to be broken in
@ Ray,..
When the Reamer's "Throat" area or, AKA "Leade area" CUTS into, the start of, the Rifling, IT produces, "Burrs"
A polished / Lapped, Throat area and Rifling edges smoothed a bit, cleans up, BOTH Copper and Carbon fouling deposits,.. way easier. And hopefully, the barrel shoots, more CONSISTENT "Cold Bore" shots that ARE "closer" to the middle of the group. ( my First, "cold Bore" shot, is only 1/4" to 3/8th's inches, away from the Group ) and Velocity speeds up, faster instead of, taking 200+ rounds to achieve, Max Break-in, speed.
I ALWAYS do MY OWN form of, Bbl / Throat, "Break in process" on New, Factory Rifles !
JB Slathered on a Patch over a Bronze Brush for a few Strokes in the Throat area and 10 strokes down the Bore. Then, I Clean, shoot 3, clean, shoot 5, clean, shoot 10, clean,.. DONE.
Bore Shines like Chrome and cleans, EASILY !

I didn't mean I don't break in barrels because they are lapped...cause most breakin lapped barrels.
Lapping just gets the tool marks that are running perpendicular to the bullet out, and leaves parallel to the bore fine finish lines. Barrel break in was to have some how a burnishing effect on the bore " "seasoning it". Shoot, clean, shoot, clean, repeat a bunch, depending on who's directions you follow, and what procedures and solvents... "prepare the bore for better accuracy and less fouling"...maybe? I don't do "that," prep the bore, shoot, then clean regimen, over and over, which is what I refer to as "barrel break in". To me it has nothing to do with chambering the rifle except the throat area as stated...but you do your procedure of barrel break in or chamber break in, however you like...most do.. fire lap, Tubb final finish, ceramic internal barrel coatings, lots of people use different methods and products...I don't. But others swear by them, and it may work for you.

New Custom Barrels, usually have, the Rifling "Lapped", at the Factory. Doubt if, most Gunsmiths after chambering,.. De-Burr/ Poilsh the Throat area, tho ! These Burrs, may cause, severe Carbon, deposits stuck to "Throat" area. The Process I use, is for New Factory Tikka's or Remington Barrels ( Not Factory Lapped ).

What really happens is the leade scrapes off copper and it gets ionized and ironed in all down the barrel giving people the false assumption the barrel itself is doing it when in reality its the leade that needs broken in. Some gunsmiths do it for you, some reamers cut it smooth enough, and some do it by repeated firing. Doesnt take many rounds to get that swarf smoothed out then its all unicorns and rainbows- barrel finally smoothed out right?
@ Dusty,..
YES,.. well put !
I try to, AVOID ALL those,. "Issues" in my Factory Tikka's and Remington Barrels !
Did My same process, to a New Criterion 6 XC, Barrel and it shoots, in the .2's and .3's and cleans, EASILY !

I chamber my own rifles, that's the area I was referring to the throat...I use JB or lately Isso paste on the throat after chambering...I check with a borescope...no burrs, a nice even transition angle in the leade...and I polish down the bore and very little at the end of the bore. Then I go shoot ... no break in need as far as I'm concerned. My chamber and throat are new and already polished.
I haven't bought a new factory rifles 22 years except for the 50 BMG. I put new quality barrels on most of my old guns. Build my own for my liking...so basically we are doing the same thing if you call polishing off any burrs left by the reamer in the throat area, barrel break in... but I don't continue the process out at tbe range. Just on the bench one time, then inspect with borescope...and done. But that doesn't mean my proceedure is for you, or your factory barrel techniques, do what works for you...cause if I thought I'd gain something by doing the range time cleaning and shoot process, I might, cause I have for years in the past...now being older I do things differently, as to what matters, or what concerns me. Some of it is how you define it. Good input, on the proceedure here, defined as "barrel break in" so we're on the same page of understanding...barrel break in, is throat or lead break in, now defined as the same. That wasn't the case 20 plus years ago.
