a krieger bbl ???...just shoot it.......
This I can't argue about since I have never owned a Krieger.
The first time I tried to break in a custom bbl with moly I got yelled at by the manufacturer.
He said to break in with uncoated bullets first. Just my .02 for what it's worth.

My last 2 kreigers broke in at about 3 shots....I spent the money for the whole "kitten ka boodle" so I figured a few more shots would not hurt a thing plus I'm firing forming brass. So I went through whole "break in" . But Really I think I might have went overbored. Good steel!!!! Good barrells!!! I have heard that if you use moly, be sure to break in with naked bullets first..I do not use moly so I have no room for intelligent comment...chris

My last Krieger also broke in with about 4 rounds. That is what I would do- load 3 or 4 naked bullets and clean after each one and then shoot groups.

I quit breaking in barrels after reading an article that said a good barrel maker puts the finish in them that he wants. The article suggested that it is arrogant of an end user to believe they can do better to finish the inside of a barrel than a professional barrel maker. The writer suggested that people are more likely to damage a barrel by running abrasives through it than by just shooting them. It made sense to me. The maker said he would void a warranty of anyone who ran abrasives though his barrels.

And there are plenty of barrel makers out there that advocate a very precise break-in process. Whom are we to believe??

Isn't breaking in about smoothing out the burrs that might be left from chambering?

How to Break-in a Barrel
-- A Dissenting Point of View
Gale McMillan, of McMillan Stocks fame, was one of the finest barrel-makers and benchrest shooters of all time. Here he argues that elaborate barrel break-in procedures do more harm than good.
Comments collected from Gale's Gun Forum postings.
As a barrel maker I have looked in thousands of new and used barrels with a bore scope and I will tell you that if every one followed the prescribed [one shot, one clean] break-in method, a very large number would do more harm than good. The reason you hear of the gain in accuracy is because if you chamber a barrel with a reamer that has a dull throater instead of cutting clean sharp rifling it smears a burr up on the down wind side of the rifling. It takes from one to two hundred rounds to burn this burr out and the rifle to settle down and shoot its best. Any one who chambers rifle barrels has tolerances on how dull to let the reamer get and factories let them go longer than any competent smith would.
Another tidbit to consider--take a 300 Win Mag that has a life expectancy of 1000 rounds. Use 10% of it up with your break-in procedure. For every 10 barrels the barrel-maker makes he has to make one more just to take care of the break-in. No wonder barrel-makers like to see this. Now when you flame me on this please [explain] what you think is happening to the inside of your barrel during the break in that is helping you.
Consider this: every round shot in breaking-in a barrel is one round off the life of said rifle barrel. No one has ever told me the physical reason of what happens during break-in firing. In other words what, to the number of pounds of powder shot at any given pressure, is the life of the barrel. No one has ever explained what is being accomplished by shooting and cleaning in any prescribed method. Start your barrel off with 5 rounds and clean it thoroughly and do it again. Nev Maden, a friend down under that my brother taught to make barrels was the one who came up with the [one shot one clean] break-in method. He may think he has come upon something, or he has come up with another way to sell barrels. I feel that the first shot out of a barrel is its best and every one after that deteriorates [the bore] until the barrel is gone. If some one can explain what physically takes place during break-in to modify the barrel then I may change my mind. As the physical properties of a barrel don't change because of the break-in procedures it means it's all hog wash. I am open to any suggestions that can be documented otherwise if it is just someone's opinion--forget it.
It all got started when a barrel maker that I know started putting break-in instructions in the box with each barrel he shipped a few years ago. I asked him how he figured it would help and his reply was if they shoot 100 rounds breaking in this barrel that's total life is 3000 rounds and I make 1000 barrels a year just figure how many more barrels I will get to make. He had a point; it definately will shorten the barrel life. I have been a barrel maker a fair amount of time and my barrels have set and reset benchrest world records so many times I quit keeping track (at one time they held 7 at one time) along with High Power, Silhouette, Smallbore national and world records and my instructions were to clean as often as possible preferably every 10 rounds. I inspect every barrel taken off and every new barrel before it is shipped with a bore scope and I will tell you all that I see far more barrels ruined by cleaning rods than I see worn out from normal wear and tear. I am even reading about people recommending breaking-in pistols. As if it will help their shooting ability or the guns'

Jerry,
I confess. I've been around Nev Madden ever since he started making barrels, and long before that.
However, the process, as I apply it these days doesn't involve shooting hundreds of rounds, or even tens. Just last weekend, I took a brand new barrel to the range, fired one shot & saw that dreadful black soot with coppery-bronze liberally thru the lands & grooves. I gave it a hit with a good metal solvent, followed by old faithful Subaru upper engine, patched out & let off the second shot, which gave no evidence of metal fouling & laid a nice grey soot at the muzzle. I cleaned out just with the Subaru this time & fired three shots to confirm that she was shooting clean - and that was it.
Happens it was one of Nev's barrels & John Giles is a fair to middling gunsmith - heck, he can shoot OK occasionally when the mood takes him - but that was the quickest walk in I've ever done on a barrel. Usually, I would expect to fire around 5 individual shots before the throat settled down.
