OK : So everyone's got an opinion ,lets hear them .  Breaking in a NEW barrel  what do YOU do ?.

 

I start by Polishing MY bore  not excessively but thoroughly then Clean the dog snot out of it !.

Followed by  fouling shots shoot one ,then clean bore  repeat  around 8-12 times generally .

I then begin too shoot either  #2  or #3 rounds and clean , I might do this 4-6 times .

I then begin load development ,I'll shoot #3 and swab for copper and adjust depending on copper left behind .

By Adjusting I might scrub bore with compound paste or shoot more foulers and clean the Dog Snot out of the bore again .

 

Generally by #50-60 rounds I'm either happy or disappointed with load or barrel accuracy and investigate as too which is the culprit !...

My barrel break in?

Initial clean :(bore snake), then load and shoot.

I've yet to see proof "break in" does anything personally.

A really rough bore may take a few more shots to smooth out, still I don't do anything special.

YMMV.

Well, I have tried to break in my Black Hole barrel and got 1 patch of black powder fouling and then no copper fouling at all. Did that for a few shots and then switched to 5 rounds between cleaning. Still no copper. Stopped messing with it, fired 150 or so over the course of 3 months and then tried again and got the very faintest of blue on the patch. 

 

I am sure some barrels could benefit from break in but it doesn't seem that BHW barrels need it at all. 

 

And I have to say the BHW barrel is the smoothest barrel I have ever driven a patch through. It almost feels like the jag is undersized.

For the last four years all I do is run a wet patch through them and a dry patch.  I then go shoot. I haven't seen a thing that helps these poly barrels on break in. I'm as likely to get a sub- 0.5 MOA group with the first five on target as not if not then within four groups. I clean the barrel after the first 75-100 rounds or so.

ARP warns against excessive cleaning ,I just clean once and shoot until accuracy drops off .Out of my 5 most accurate guns 3 are ARP 6.8s so who am I to argue .

More barrels have been worn out or damaged by cleaning than ever have been shot out. A quick wet patch to clean any dust/dirt/grease leftover from the rifling process, a dry patch to ensure it's clean, then go shoot for groups.

An article written about a precision barrel maker and his take on it. Also where the idea of break in originated possibly?

Old Gail wrote that years ago. Smart man.  BTW the BHW barrels have special wax in them that is best left in place during the first shots It seems to help longevity on the barrel. Something about a bare bullet in a dry bore causes issues.

Initial clean with a bore snake, I fill the magazine, I shoot the magazine.
Clean it once you see a drop in accuracy. For me once a year on some rifles, followed by a range session.

He'd definitely give you some good advice.

You going to the Armory get together? NRA Whittington center with lots of long rang shooting going on!

Before Gale McMillion died he told me barrel break in was desigend by barrel makers to sell more barrels as all they did was to accelerate wear and was totally useless...........

 

OK : So everyone's got an opinion ,lets hear them .  Breaking in a NEW barrel  what do YOU do ?.

 

I start by Polishing MY bore  not excessively but thoroughly then Clean the dog snot out of it !.

It's too bad my big trip this year is to my 50th high school reunion. I'd love to be there.  As fro teaching a class ..I'm not anymore talented than you guys I just paint my self in a good light.

 

My specialty is MATH and how to apply it to the gun. Plain and simple if the math is right and the aim is true, along with maybe twenty other things, it'll be a hit. Mild dots are one of my big things and how they are used to range targets or establish target sizes. Throw in a dose of trigonometry and you have most of my secrets.

 

My approach to shooting is also quite mental, in a good way BTW, in that prep of he brain really pays off. A bit of self esteem/ego that can be pulled up and not be bruised too badly when things don't go perfectly well. I sure didn't develop it but I've found that over time lots of things can be improved with the right set of thoughts. I learned it early on bowling for money. I don't always get solidly into the mind set as much as I should but it's in there.If you read the little vignette on my shooting the groups with the 6X6.8 the other day when the SWAT boys started to watch I can tell you I dug deep that day and buzzers get me into hyper-drive. It's there when you develop and have success with it over time.  

 

This is a little clip that only takes a bit of substitution to apply to us. If I could teach you all one thing this would be it. It was a huge changeling teaching my classes for M/o's, snipers,  over the years with younger guys with some experience but no real foundation in precision shooting. They rarely had the mind set when they got to class and other than the dry math I tried to get them to transcend to that level. Those testosterone charged young studs had to be gentled down to produce on demand and I like to think that they left with the wisdom and experience of the Gene Wilder looking guy who was just a nurse.

 

 

Just some thoughts that are a tad of topic.  Now if you'll excuse me I have 300 cases that need filling.

 

Greg

So according to You .More Barrels have been worn out by cleaning rather than by  Throating ?. ( erosion caused by direct impingement of gas and solid particles traveling across the bore surface.)

 

With Precision barrels such as Lija and Schnieder break in isn't as crucial as with other barrels  IMO . The a fore mentioned are pretty much hand lapped at factory but other off the shelf  barrel and Rifle manufacturers aren't as demanding or picky , their production orientated not precision driven   !.

 

As with any other subject there are  fiction and  tales then there are Facts with proven results , I shall stick with the latter ...

You're kind of being a jerk here. You asked what we (other members) do, I offered an opinion. You countered that and offered up opinions supporting your argument. I decided not to argue, and simply said you do your thing, I'll do mine. Now you suggest my opinion is "fiction and tales", and yours is obviously "facts with proven results"? This is the kind of crap that made gmor almost a pariah around here. His opinion is the only correct one based in "fact", everyone else is simply spewing lies and hate. 

 

Don't be a gmor.
