| Rubbing or Polishing compound to lap barrel? | Login/Join |

I was curious if Flitz or any other type of light abrasive would polish the inside of my barrel, since I already have it on hand. | ||

I wouldn't try it. It may do no damage at all. But what if it makes the barrel just a red hair too loose? I'm sure there are bore-polishing solutions out there, but I know of none. Maybe some of our more knowledgeable members can give us the skinny... | |||

Flitz is/was used by a lot of folks to remove copper. Not so necessary now that we have so many good copper cleaners. The best way to polish a bore is still to lap it. Some people like fire lapping with grit impregnated bullets and some say it is damaging. you can probably find a lot of comments by searching the site for either Flitz or fire lapping. "Experience" is the only class you take where the exam comes before the lesson. | |||

You could stroke flitz in and out till the cows come home and achieve nothing. Just shoot it smooth. ________________________________________________ Maker of The Frankenstud Sling Keeper Proudly made in the USA Acepting all forms of payment | |||

So flitz is out. What about pushing through about 10 patches with rubbing compound and 10 with polishing compound? I am just curious cause my frickin Browning a-bolt shoots the first 5 shots great, then the groups open up. | |||

No, wasting your time. Get a specific firelapping compound. I recommend NECO #220 to get rid of rough tool marks and #800 to polish. Both cost $15.00 each. You rub the stuff into bullets, load them then shoot them at a reduced velocity. Clean between each shot. You can also order a complete kit of 50 bullets with the lapping compound already applied for $50.00 | |||

Embarrassed to admit I tryed some dupont rubbing compound "once" a long time ago on a old frosted barrel just for the hell of it cause there was a can I happened to spy sitting on my self, Didnt do shit and it turns into a mess as I remember | |||

Sounds good guys. I guess there is a reason for fire-lapping kits. I think I will try one of those then. Which is the best for the buck? | |||

Just curious... What rifle and barrel do you have and why do you think it needs to be lapped? DOUBLE RIFLE SHOOTERS SOCIETY | |||

NE, It is a Browning A-bolt 300wsm with factory barrel. I broke in the barrel correctly (depending on who you talk to) when I first bought it. Since I have put about 400 rounds through it. Accuracy degrades pretty fast in it with out my secret barrel lube (white lithium grease)  | |||

Before you lap it, try giving it a good cleaning with J&B Bore Paste or Rem Clean. Finish up cleaning with ProLix. It is made by an Idaho company. www.prolix.com I do not think it is a good idea to shoot a highpowered rifle with grease in the barrel... DOUBLE RIFLE SHOOTERS SOCIETY | |||

I was joking about the "secret lube." I just put a little spry of lithium on a patch and work it all over the patch, then run it followed by another patch. My rifle shoots much better when I do that every 3-5 shots. Its crazy, but works. I didnt think there would be enough grease left over to hurt anything since it is just a tiny bit on a patch followed by a dry one. | |||

MRAMSAY, I DO NOT mean this (seriously!) to be a wise-ass reply to your post but...if you have to ask "how to" in the first place you really shouldn't be doing the work yourself if this particular rifle is valuable to you. Pay a professional to do it right and save yourself a potential disaster in case you screw it up. On the other hand, if it's a gun that you don't care much about or just want to mess around with, then go ahead and see how it comes out. Good Luck either way! Just my 2 cents!

Leo, You aren't just born knowing how to do things. You have to learn from those that know how to do it, so that is what I am trying to do. I enjoy this WAY too much to always take my guns to a gunsmith for every little thing. I understand your point, but most of my guns I am learning on are not worth a bunch of money. Tsturm, I'm not flinching till at least round 20 | |||

In that case then I would definetly do it myself. Let us know how it goes and good luck!!

The 'trick' with fire-lapping is preventing the abrasive grit from getting into places it's not supposed to go. To this end, I make myself 'fire-lapping' bullets that hold the abrasive inside the case neck. The beauty of fire-lapping is that is is more vigorous at the begining of the bore than at the end. I have had a rusty bore lapped by a gunsmith which I then fire-lapped my way, exposing sharp rifling that was until then, rather 'rounded' and shallow. If only cleaning and polishing the bore is the desire then shooting paper patched bullets is the thing to do. Some folks have said it can take as many as a hundred paper patched bullets to achieve best accuracy. (Paper patching will make a worn bore shoot again - due to 'custom' sizing of the bullet to the throat and bore). Regards 303Guy | |||

I suggest everyone should look at Krieger barrel's Website and click on the barrel break- in heading. They have concluded that J-B Bore Cleaner, Flitz, etc. does NOT harm a barrel in any way, in other words it does NOT remove steel. They also say DO NOT fire lap their barrels, "Warranty Voided". "The right to bear arms" insures your right to freedom, free speech, religion, your choice of doctors, etc. ....etc. ....etc.... -----------------------------------one trillion seconds = 31,709 years------------------- | |||

The idea of shooting a sand covered bullet thru my bore gives me the willys.  Aim for the exit hole | |||

I would personaly never use a firelapping kit, but know people do with good results. I use JB bore polish. It is differant from the paste and works absolutely beautifuly. As someone mentioned, it does not remove metal. It is too fine to open the bore up, but it will smooth out tool marks and help reduce fouling and prolong accuracy before you have to clean again. The KG polish is good too. Use these at regular cleanings and after a couple times, you will see a visible differance in the bore, especially if you have a bore scope, and get less fouling etc etc. That is my professional opinion. Either that or pay a professional to do it for you! Curtis | |||

Several decades ago, it was common for match shooers at Perry and other locations to apply a product known as "BonAmi" with bore mop and finished off with hot soapy water to clean a bore and polish as well. The product's motto was "barely scratch the surface..." meaning a polishing compound. As mentioned, tooth paste will work fine. Engine cases on cycles, show cars, etc. use a product known as CimiChrome which can be found at cycle shops and serves as a very good bore polish compound. Krieger's position on such application is good enough for me for I have found their barrels work well and are not prone to a lot of fouling. | |||

Hey MFD, That is darned close. Your memory is better than mine. Perhaps that is what it said before the can I have. I have a relatively new can of Bon Ami in my hands right now. It says, "Bon Ami won't scratch fine hard surfaces as other cleansers do.* *Bon Ami's feldspar and calcite abrasives are softer and milder than the silica (quartz) found in other cleansers. ----- Many years ago in one of the Gun Rags, Bruce Hodgdon recommended making a Paste with Bon Ami and your favorite Bore Cleaner to remove H870 Residue. Many of us used a lot of H870 because it was relatively inexpensive and you could use all of it that you could cram in "most" Cases with Heavy for caliber bullets. As you used lighter weight bullets, the H870 did not burn as clean and it ended up leaving a very tenacious Residue just ahead of the Throat. But, the Bon Ami would take it right out. Thanks again Mr. Hodgdon for that excellent tip. | |||

Years ago, we got a whole bunch of BRNO 452 rim fire rifles. And a discussion resulted after we looked at the barrels with a bore scope. Some barrel looked pretty decent, and one in particular looked a bit more rough than the others. We decided to shoot ammo with abrassive we got from NECO. I have no idea how many rounds were fired through that barrel. But we did get it mirror smooth! The funny part was, that rifle never shot as well as any of the other rifles that did not have their barrels smoothed. | |||

Use JB bore paste. I talked to Frank White of Compass Lake Engineering, on Commerical Row at Camp Perry, about barrel cleaning, life, the universe, and everything. Frank sees more barrels and barrel problems that most people ever will. Frank claimed that barrels are often sent back by owners claiming the tube lost its accuracy. Through the use of his bore scope Frank claims that he has seen impacted carbon (and maybe other stuff) in the barrel throats. In his experience chemical cleaning will not remove these deposits. So Frank recommended the occasional use of JB Bore paste. This will mechanically remove the impacted gunk and has radically restored accuracy to barrels. You have to be careful with abrasives. I do not recommend ersatz abrasives. Mess up a $300.00 barrel and you wil regret it. Only use abrasives sparingly. They add wear to the barrel throat. Also funnies happen. On 308 barrels with 3500 plus rounds, I have seen the zero radically change after cleaning with JB Bore. I mean MOA changes in standing, and it has taken as much as seven rounds before the barrel fouls to a stable state. Shoot, examine the shot placement, click to compensate for the changing elevation. Shoot and pray to God that the elevation stops changing before the score goes all to heck. Your 300 Win Mag is a high intensity barrel and it is not unreasonable to believe the throat is all clogged up with gunk at 400 rounds. | |||

Exactly my point I have been on my soapbox about for years!!! Most are just dirty and the user does not know any better. Without a Bore Scope you are just guessing unless---You use JB or as I use Iosso to get the tube clean!! My Bore Scope is the best tool I own... | |||

Isn't JB Compound "Dimetrious(SP?) Earth"? | |||
