I would like to know the best way to break in my new AW.

Has anyone seen this website before?

Proper Barrel Break-in
ensures long Barrel Life

Proper barrel break-in procedures are crucial for top accuracy and performance. More barrels are damaged by cleaning rods than by any amount of regular shooting a person may do. If not done correctly, one can do more harm than good.

The barrel break-in technique we endorse, is the “Speedy Method” named after Speedy Gonzalez, owner of S.G.& Y Rifles. Speedy is well known in Benchrest disciplines; national champion, world record holder, and Hall of Fame inductee in the National Benchrest Shooters Association (NBRSA). He has given permission to share with you, his expert advice on the correct method of barrel break-in and cleaning.


Rifle Cleaning the Right Way
Barrel break-in. Many of our customers upon taking delivery of their new rifle or barrel are in a quandary as how to go about breaking in their rifle for maximum life and accuracy. With so much written in magazines these days stating use this, don’t use that, brush, don’t brush...what’s a person to do?? At S.G.& Y. Rifles, we have a unique opportunity to inspect many rifle barrels on a daily basis with our video borescope. Consequently, we see the results of a variety of barrel break-in and cleaning procedures, and most of them leave the rifle owners with their mouth agape when they see the fruits of their misinformed labor on our color monitor. We have seen practically new barrels ruined with less than a hundred rounds shot through them by some of the crazy and sometimes humorous barrel break-in methods. Anyway here goes for what it’s worth.

A. Bore guides- If you don’t have one, get one! Without a good bore guide you are just wasting your time trying to break-in a barrel or cleaning it for that matter. More rifle barrels are destroyed by cleaning without a bore guide than by shooting! There are many types and brands of bore guides available on the market and range in price from $5.00 to $50.00. The only one we recommend is the Lucas two-piece bore guide. They are the best insurance you can buy for that new barrel. All other bore guides in my opinion are only good for keeping the solvents out of the trigger and action.


B. Solvents - We recommend Sweets 7.62 for copper and a *solvent mix of our own (Actually Pat McMillan gave me this formula) for powder fouling and for cleaning/storing your rifle for the next match or season. This Speedy Formula is made as follows:

Mix 2/3 rds. Hoppes No. 9 Plus Black Powder solvent with 1/3rd. Regular Hoppes No. 9 Nitro solvent. Let this mixture set overnight and it will form a sort of gel that adheres very well to the brush and cuts powder fouling to a minimum.

* Note: Butches Boreshine may be substituted for this Speedy formula.


C. Procedure for “Break-in” - Before firing that first shot, clean the barrel as if it had been shot by following these simple steps.

Step 1. Insert Lucas bore guide into receiver and chamber. If you don’t have one stop here and get one, if not, just shoot your rifle and forget trying to take any care of your barrel at all. If you do have one, proceed, and give yourself one “At-A-Boy” for being astute enough to have purchased the proper tools for the job.

Note: One “Aw-Sh*t” wipes out ALL “At-A-Boys”.

Step 2. Run one wet patch of Sweets through the bore and let soak for approximately 30 seconds. Do not patch this out.

Step 3. Next, run the brush through the barrel only enough to expose the entire brush. Yes, I know that you still have 12 more inches of cleaning rod you could push out the end of your barrel but we want to protect that new crown. Also, if that rod hangs out that far, you will eventually start wearing down the rifling at the crown from about 4 to 7 o’clock. This is very bad “JU-JU” for accuracy. OK, back to our next step. Once the brush is exposed, saturate it well with our Speedy Formula or Butch’s Boreshine and SLOWLY run the brush through the barrel 10 complete back and forth passes while keeping the rod as straight as possible. This is when the Lucas bore guide really pays for itself! Remember, the key word is slowly. We are not trying to break any land speed records today. Let this sit a minute or two and proceed to the next step.

Step 4. After you have let the barrel soak for a few moments, saturate a patch with the Speedy Formula or Butch’s Boreshine and pass it through the bore. Follow this with 2 dry patches and then dry the chamber with Brake Kleen or lighter fluid. Next, gently wipe the crown off with a soft cloth and lube your bolt (lets not gall the lugs just yet). Now, your ready to shoot your first shot. Then follow the schedule below to complete your barrel break-in.

1. Clean barrel / lube bolt / 1 shot.

2. Clean barrel / lube bolt / 5 shots.

3. Clean barrel / lube bolt / 10 shots.

4. Clean barrel / lube bolt / 10 to 15 shots and clean again.


D. Additional Barrel Break-in and Cleaning Tips -

1. Each time you clean you may also follow the last dry patch with a patch soaked with LOCK-EEZ. This is a graphite powder suspended in a quick evaporating carrier that coats the bore slightly before passing that first round through a completely dry bore.

2. We are always asked about powder fouling and how to remove it. The only product that we have seen that really does a good job on powder fouling, especially on the carbon ring that forms just ahead of where the neck ends in the chamber, is IOSSO Bore Paste. This is used with a Pro-Shot nylon bristle brush and worked slowly in the neck and throat areas, then slowly down the entire bore. Follow this up with a few wet patches, then dry the bore as usual, and your ready to shoot.



E. Follow the outline above for your regular cleaning program and I promise that your rifle barrels will deliver their greatest accuracy and life without a lot of grief and hours of wondering if they are clean.

Good Shooting,

Speedy Gonzalez

Step One: Insert round into chamber
Step Two: squeeze trigger
 
Re: Barrel Break in for Accuracy International AW

Shoot it. After your first trip maybe clean it. After that shoot it till the groups fall off. My AWs first trip was 150 rounds of match grade ammo. My AE mk1, AEmk2, and AW have all shot phenomenally even without a real "break in" by doing what I just suggested. You'll be surprised how long the barrel can go if its anything like my rifles have been... My AE mk1 went about 900rounds suppressed before it started to open up slightly. I didnt clean until around 1200. So.... Just shoot it.
 
Re: Barrel Break in for Accuracy International AW

Decide which way you're currently leaning toward (break-in <span style="text-decoration: underline">OR</span> no break-in). Read posts in this forum for one (1) week. You will easily find several threads during that time period that support your position one way or the other (LOL).
 
Re: Barrel Break in for Accuracy International AW

I switch barrels somewhat frequently on my AW. On a new barrel I tend to shoot it until I see "unusual" pressure signs relative to the previous loads in a similar barrel. At this point I clean it. On one 308 barrel I went around 800 rounds before cleaning (my data book is not handy), on a 260 barrel I have been cleaning it every ~100 rounds since it seems to be "tight" and would show excessive pressure during matches.

YMMV
 
Re: Barrel Break in for Accuracy International AW

Haven't broke in a barrel in at least 10 years, but once and a while I have cleaned them after shooting it, not with anything as harsh as recommended above, I tend to avoid anything harsh, like Sweets.
 
Re: Barrel Break in for Accuracy International AW

I have gone through 3 AIAWs without EVER done any breaking procedure. Guess what, they still shoot better and I will ever be able to. Just shoot it and enjoy your rifle.

I have followed this advice for the last 2-3 years and done some non-scientific research myself. I will not go through the hassle of breaking in another barrel. After experimenting with about 6 different barrels now, I can tell you firsthand breaking in a barrel makes no appreciable difference. I rarely clean the bore either, just when accuracy falls off. I do however like to wipe down the gun with some rust preventative if it is not coated. Just go shoot.
 
Re: Barrel Break in for Accuracy International AW

I don't use Sweets. But if I did I wouldn't mix it with any other solvent and I wouldn't leave it the barrel for too long. If you are really set on breaking-in a barrel, Butch's Bore Shine and Kroil work just fine.
 
Re: Barrel Break in for Accuracy International AW

dont have an AI, but i do have a krieger barrel on my surgeon 338lm, 300 rounds in with no break in and steel at 1200 yards is effortless, around 2 inch groups at around 500 yards

although i am not working with small caliber stuff right now, when i was, we never did anything special for break in other than sending about 20 rounds down range prior to testing
 
Re: Barrel Break in for Accuracy International AW

the only thing barrel break in does is make the ammo companys more money!
 
Re: Barrel Break in for Accuracy International AW

none of our AW,s have ever been broken in apart from brought to the range and just shot. they are all stil hammers. when we are finished for the day and if we are shooting again the next day the barrels are not cleaned. if they are goin back into stores and not going to be fired again for a while they get a patch pushed through and then a wet patch with some oil on it then a dry patch after, keeps the quartermaster off our back. thats it, no scrubing. couldnt even tell you what oil it is , whatever the army has to give us is used,could be cooking oil for all i know!. i dont bother breaking in any of my own personal rifles either.waste of time,ammo,money imho.

and $$$ for the barrel makers and the smiths to intall them...
 
Re: Barrel Break in for Accuracy International AW

I run a couple of wet patches through the new barrel (my new 5R showed presence of copper) followed by several dry patches.

I then shoot it. I might clean it after the first range trip and then again to check clean cold bore. I will usually go to somewhere around 100 rounds or when accuracy falls off.

All barrels will "break in" on their own, all that constant cleaning is a waste of barrel life, patches, solvent and time.

Foaming bore cleaner and hoppes #9 or shooters choice are your friend.

Don't forget about the barrel companies who are replacing prematurely worn our barrels.
