Have my swedish mauser back from the 'smith - rebarrelled from 6.5x55 to 257 Roberts. Looks good - never had to 'break-in' a new barrel - any advice would be appreciated at this time. "Shoot hard, boys." | ||

You can go through as much work as you want but I'm not sure I've ever seen a difference. If you are looking for something to do, Fire one shot and put a little JB paste on a patch run it down the barrel. Follow that with a patch of sweet's. Finally, run dry patches down till the barrel is clean. Then repeat the process for your first 10 shots.

Don't get too worked up about it. I usually shoot one and clean for 20 and then go from there as normal. The main reason is for ease of cleaning. I have not found that much difference in accuracy except for one strange barrel. I think I do it mainly for Westpac's reason.

I stopped with the tedious break-in procedures. I polish a new bbl. with JB and that's it. Also, I never let copper build up and take it out every 20 shots. André DRSS --------- 3 shots do not make a group, they show a point of aim or impact. 5 shots are a group. | |||

Just shoot the farkin thing. If the barrel builds up heavy copper fouling, send the rifle back to the guy that made the barrel with a note that you want HIM to make it right. Lifes to short to spend your time trying to do someone elses job | |||

I guess I'm like the others who have already posted; a JP paste polish and flush before shooting it the first time, clean between shots until fed up with the process or you need a beer, whichever comes first. _________________________________ AR, where the hopeless, hysterical hypochondriacs of history become the nattering nabobs of negativisim. | |||

one of the quality barrel makers turned me on to the following process and although laborious has always been very succesful for me. it must have been hart or shilen but i don't remember which one. clean barrel down to bare metal before shooting. fire one shot, clean with powder solvent, then slowly push patch with copper solvent threw barrel, i use sweets, but there are other good brands. noting amount of color indicating copper fouling. following instructions and cautions on copper solvent clean with same. test by slowly running another patch with copper solvent threw bbl. i use a plastic jag for test. if bbl is not showing any copper repeat this process until bbl. doesn't show fouling after one shot. then increase to 2 shots same process, then 3 shots, then 5 shots. if barrel will not clean to bare metal by using onr treatment of copper solvent. use jb bore compound, you must get bbl. down to bare metal between shots. the last bbl. i did came out perfect after 4 shots, one 2-shots, 2-3 shots.bbl. did not show any copper on first 5 shot group, another hand-lapped bbl. never did show any copper fouling. today both bbls. don't copper foul at all. velocity is like a new car, always losing value. BC is like diamonds, holding value forever. | |||

Me's thinks breaking in a barrel is a PITA. If one spends the money on a quality barrel to begin with, there shouldnt be much of a problem anyway. I use to be anal about it when I first started installing barrels, but i dont anymore. One spends good money on a aftermarket barrel of quality should take care of it, and not let it get out of hand. Run a dry patch down a new barrel and feel how smooth it is from the lapping...NICE! I have not seen any diffrence between the two, just take care of it and it'll take care of you. You'll know when it needs cleaned or not. _____________________ Steve Traxson | |||

Copper fouling on a new barrel is caused by the new reamed throat area. Don't wear the barrel out cleaning it just because the throat will cause the coppering until the throat is broken in. If the barrel is rough enough to copper on its on, you need to send it back. Butch | |||

Some say do, some say don't. I happen to be one that does a break in, old habits hard to quit, but as for JB, polishing compound use, normally do only the first third of the bore, throat and 10" or so beyond for that is where the copper is picked up initially and once that area is burnished, usually no more copper problems. Match shooters would prefer going to a major match with some several hundred rounds or so through the bore and believe that those rounds have smoothed out the entry area of the bullet and you will hear the term "sweet" used to describe that condition. Have had knowledgeable 'smiths and shooters also say shoot a match and it is ready to go. Go figure! | |||

Is JB bore paste an abrasive. I'm told that it does have abrasives in it, and wouldnt using a liquid cleaner be less harsh when used right. I have some JB here in the shop but have never used it after finding out it does have added abrasives. Anyone with a bore scope look after using the paste to see if maybe the land and grooves have been rounded or altered? I have a feeling the abrasives are pretty mild and non-agressive, but i still wander! I was also told of one barrel maker who would not gaurantee their barrels if they knew JB bore paste had been used, But i got this second hand so i cant be 100% about this or any of it...This is why i ask! _____________________ Steve Traxson | |||

I belive the abrasive in JB bore cleaner is vegetable matter. As I understand it< JB will remove the powder fouling and "abrade" the copper off the steal and will "knock" of the the microscopic steal "ridges" but as far as removing barrel steal I suspect shooting removes more "ridges" than any amount of JB will.

Wallhead,break the barrel in by soaking the bore with a pentrating oil like WD-40.This will produce a SUPER accurate bore.Put the red straw in from the reciever end and blast the chamber and bore with oil.Leave the bore soaked with oil for a few days and then wipe it dry with patches before you shoot.This will reduce damage to the rifling when the bore lands are at their most fragile stage-the first few shots.You should then use JB for every three rds for the 257 Roberts,and remove all copper.This should be done always. | |||

Whoa! I don't think I will be using JB bore paste after I shoot my gun 3 times. I can handle cleaning my gun every 20 shots or so but not 3. | |||

For a normal barrel I shoot a couple of rounds and clean it, for a couplle of cycles. For a hand lapped barrel, I shoot one round and then scrub the throat clean where the chambering left the reamer marks. I repeat that 10 times. Why bother getting a hand lapped bore and leaving a sewer pipe in front of it that peels copper from the bullets?

Yes, for break in. but not every 3 shots after. | |||
|
| one of us |
I thought it was similar to the 270win or 30-06 but see that it is more like a 308win or smaller.Therefore,I would clean after 3 only for break-in and every 60 if I am using molly coated bullets or 20 if uncoated. | |||

panther piss and chickenlips ground up fine.. In other words, there's alot of voodoo around this... Fire 1, clean, should be 20-30 mins from first round to end of cleaning Fire 2, clean should be 20-30 mins from first round to end of cleaning Fire 3, clean. should be 20-30 mins from first round to end of cleaning The purpose of breaking it in is to fill all the micro holes and smooth any rough edges ...

AR, might I suggest reading a little closer? If I install/have installed a Shilen, Lilja, or other quality barrel and it's a copper fouling bitch, you can bet your ass that Doug, Dan or whomever will be getting that barrel back. Weather they chose to fix it or replace it I don't care, but I'll be damned if I'm going to be the one doing it. Let's put it this way, you go buy a new car, and if the tranny pukes on the way home from the dealer are you going to return it for warrenty repair, or are you going to pay to have a new one installed? Same thing, factory defective, factory repair. | |||

This was sent to me a few years back and I just ran across it whilst thumbing through some e-files. Another perspective on the subject.  Gale McMillan Senior Member posted September 25, 1999 10:10 AM -------------------------------------------------------------------------------- The break in fad was started by a fellow I helped get started in the barrel business. He started putting a set of break in instructions in ever barrel he shipped. One came into the shop to be installed and I read it and the next time I saw him I asked him what was with this break in crap? His answer was Mac, My share of the market is about 700 barrels a year. I cater to the target crowd and they shoot a barrel about 3000 rounds before they change it. If each one uses up 100 rounds of each barrel breaking it in you can figure out how many more barrels I will get to make each year. If you will stop and think that the barrel doesn't know whether you are cleaning it every shot or every 5 shots and if you are removing all foreign material that has been deposited in it since the last time you cleaned it what more can you do? When I ship a barrel I send a recommendation with it that you clean it ever chance you get with a brass brush pushed through it at least 12 times with a good solvent and followed by two and only 2 soft patches. This means if you are a bench rest shooter you clean ever 7 or 8 rounds. If you are a high power shooter you clean it when you come off the line after 20 rounds. If you follow the fad of cleaning every shot for X amount and every 2 shots for X amount and so on the only thing you are accomplishing is shortening the life of the barrel by the amount of rounds you shot during this process. I always say Monkey see Monkey do, now I will wait on the flames but before you write them, Please include what you think is happening inside your barrel during break in that is worth the expense and time you are spending during break in. _______________________________________________________________________________ This is my rifle, there are many like it but this one is mine. My rifle is my best friend, it is my life. | |||

I think I know what barrel maker he is speaking of. I don't think he makes even close to 700 barrels a year now. Butch | |||

I think JB is diatomaceous earth (fossilized remains of diatoms) in a petroleum suspension. Diatomaceous earth is used in other applications for mild polishing like toothpaste. It may have Fuller's earth in the formula as well. So if you run out of Colgate, you have an option in the reloading room... "Experience" is the only class you take where the exam comes before the lesson. | |||
