This is a general method for breaking for the average shooter. The important part is do not damage the crown when inserting the cleaning rod. Use rod stops to have better rod control and crown protectors to guide the rod if you can not enter from the breach.
Breaking in a barrel (pics coming soon) THIS IS FOR A RIFLE THAT WILL NOT BE SHOOTING MOLY COATED BULLETS 1. We use the fire three rounds then clean method, we do this for 3 cycles then clean every 10 shots for another 3-4 cleanings. This has worked well for us and MANY of our competition shooters who buy from us, you will hear the advice shoot one clean one for some UN-Godly amount of rounds, I personally think this is overkill and a waste of time. Again, only my opinion. I have tried many methods on different types of barrels, I have noticed no increase in barrel life or accuracy with a clean after every shot approach. 2. We always use a bore guide and a one piece cleaning rod with a swivel handle (Dewey, etc) NOTE: GO SLOW!!! Watch the crown (end of barrel) and chamber (where cartridge case sets) damage to this area will affect accuracy, treat it with extreme care) 3. We soak bore with a wet (CLP) cotton patch (let sit a few minutes) 4. Run Brush through barrel 3-5 times 5. Run wet patch back through 6. Run a dry patch through 3-5 times until coming out clean and copper free. NOTE: The best way to get this baby clean is use a solvent made to remove copper (there are 100's in the market place), let it soak for time recommended on bottle, a bluish green frothy gunk will come out, this is the buildup of copper. http://www.rbprecision.com/rb_precision_ar15_performance_tips_.htm I would recommend J-B Cleaners and Paste st Brownell' s or local gun shops for periodic cleaning. For copper removal there is nothing better an Sweet's at Brownell's or local gun shops. Just read direction carefully and do not soak for long time period. |

I saw a write up, that quoted reputable people about barrel break-in, basically recommending against using Moly Coated bullets and instead use moly products to coat and burnish the Moly into the bore of the rifle. The logic being, a lot of the moly gets scraped off the bullet in the throat of the barrel and then it can harden in there by the heat/press and it can't be removed without a big risk of damaging the throat.
http://www.internetbankingcaixa.net/barrelbreakin.shtml It appears the are talking about Match Grade Barrels, but what is stated in that write-up makes a lot of sense. Burnishing Moly or a similar substance that can be Burnished into the metal of the bore (forced into the pores in the surface to stay there) "SEEMS TO ME" to be the only thing you coat a bore with that will last longer than the next shot. A coated bullet, it makes sense to me that most of the coating on the bullet is scrapped off at the throat and what ever remains is only wiped on the beginning of the bore, NOT the entire length. Someone with a lot of experience with Moly Coated bullets may have another opinion, OR, post a warning on how to avoid what they talk about in the write-up. I've got a lot less experience with NEW barrels than a lot of people on this board, take this with a grain of salt, but IMO, a barrel does break-in, its just for most barrels, all that is required to do a proper break-in is normal shooting with a little caution, that's it. Yes, there are imperfections in the bore, that rounds fired down it will wear down, etc. BUT, anything you coat a bore with is removed by the next bullet traveling down the bore. I think you'll see most people recommend just fire like normal to break-in your barrel, I'll only add the use a little caution, the first 100 shots are NOT the time to abuse your barrel with MAG Dumps and heavy rapid fire, shoot and clean it at least once before you start in on the heavy stressful usage. If you have a chrome lined bore, seen lots of people and manufacturers state there is nothing you can do to change the break-in, just shoot it. |
