Re: Loopskoonmaak
Beretta, dankie vir terugvoer, wees asb meer spesifiek. Ek was nou die dag by Agra se wapenwinkel in Windhoek en toe vra ek hul om die produk te bestel, verwysende na die artikel in MAGNUM. Die een verkoopsman noem toe dat dit k#k is. Ek het vir Koos Barnard van Magnum geskakel maar hy was nie op sy sel beskikbaar nie, het toe maar 'n boodskap gelaat. Sal dankbaar wees vir terugvoer.

Re: Loopskoonmaak
Manne.
Ek wil aansluit by Jaracal - ek is fanaties oor 'n skoon loop en die beste produk wat ek in my lewe nog gebruik het is Eliminator van Bore Tech - hierdie produk is absoluut ongelooflik!
HIER KOM DIE BESTE DEEL:
Iemand(JB) het gevra hoe jy 'n kroon skoonmaak - veral as jy met 'n knaldemper geskiet het?
Vat 'n lappie en spuit bietjie Eliminator op en plak hom voor teen jou kroon vas - los hom daar vir so 5 - 10 minute en vee dan die ergste swart aanpaksel af, ek herhaal hierdie stap 2 tot 3 keer waarna ek Eliminator op 'n laaste lappie spuit en dan die laaste bietjie swart afvee. Geen geskuur of 'n geborsel nodig!
BELANGRIK!!!!
Moenie Eliminator op jou houtwerk laat kom nie - hy vlek die afwerking en vreet die vernis op die kolf.
Koop gerus hierdie produk vanaf S&O @ ongeveer R400 vir 400ml - PUIK produk.
Groete.
Jaco
O ja, het amper vergeet om te noem, moet ook nie dat die Eliminator op vroulief se nuwe deepfreeze drup en dit dan nie afvee nie - dit maak sulke lelike geel vlekke op 'n Defy!!! Vroulief is nou nog vies oor daai een!

Hi daar.
Ek gebruik water en Cleen Green in my voorlaaier. Ek wil jou net s? ek dink nie jy moet daai pad loop nie.

Interesant om al die skoonmaak goed op die mark te sien. Ek het nie al die pos gelees nie maar het iemand al die nuwe produk in die Magnum probeer?

Robla solo is n goeie kooper solvent, maar het n sterk amoniak basis. As jy deur die proses is om koper uit die loop te haal, sal ek jou aanraai om eers n olie lap deur die loop te sit, en dan weer die olie uit te haal, dws die loop droog te maak.
Ek het dit lank gebruik, en een aand my geweer mooi silver skoon gemaak, net na die koper uit was en lappie skoon uitgekom het, het ek gaan slaap, die volgende oggend wou ek seker maak die loop is skoon, en het n skoon droe lappie deur die loop gesit, groot was my verbasing toe die lappie rooi v/d roes uitkom. Ek het toe maar n olie lap deurgesit en weer die loop drooggemaak. Vandaar altyd na die loop skoon was eers weer n olie lap deurgesit en dan weer loop drooggemaak.

Re: Loopskoonmaak
Ek volg 'n paar riglyne:
1. Ammoniak basis produkte word nie op vlekvrye staal gebruik nie.
2. Ek gebruik net 'n brons borsel as ek roes uit 'n klient se geweer moet uithaal. My en my kliente se gewere weet net van lappies en moppe.
4. Pasta en boresnakes is goeie produkte as mens lope en teleskope ook verkoop en 'n wapensmee afdeling het. Dit bring baie besigheid.

Wat doen jy met die lappies en moppe...
Vertel meer vand e nitraat ding wat dei koper verwyder en nie loop skde doen nie,
Ek raai maar net, Sien Hedrik het mooi handleiding geskryf vir loop skoonmaak..
Maar toe ons ebgi het en slegs die amoniak basis produkte beskikbaar was , het ons ook gelees dit is onskadelik vir n loop.
Sommer so in die algemeen... wat gebruik jy vir "blink loop" en wat gebrui jy vir n "swart loop"?
Is daar n verskil?

how does a bore snake damage a rifle if you pull it out straight ? i mean it's made from copper and cloth both of which are softer than steel .
i know you say that of the 4 rifles you've inspected with oval crowns the owners used bore snakes , but were they bore snakes or those pull thoughs we used in the army ? the US army basically issues bore snakes to the troops and they test every thing a million times before using anything .
i'm not saying it doesn't damage the crown but how ,what causes the damage ?
thanks bobby

Ek gebruik slegs Boretech se produkte nl: Copper Remover en Elliminator, en M98 wat plaaslik deur Gerard vervaardig word. Ek het nog nooit iets beter gesien nie, en glo my, ek het al alles op die mark probeer.
Ek trek net n olie lappie deur as ek klaar skoongemaak het. Probeer dit, en jy sal nooit weer terug kyk

En so het elkeen sy geloof wat hy in glo.
Ek is weer van mening dat niks beter werk as Ballistol se Robla solo mill copper remover. En daarna 'n goeie penetrasie olie en Ballistol olie.

Hallo Piet
Moet eerlik wees , wag al rukkie dat jy vir ons iets se omtrent die skoonmaak van lope.
AS ek so voorbarig mag wees, vertel bietjie meer van julle manier van skoonmaak as jy nie omgee, van die begin tot einde en produkte wat jy sal aanbeveel.
Met daardie groeperings wat julle skiet moet gewere defintief goed na gekyk word.
Baie dankie

Moet ook byse ek maak my loop eers na sowat 200 skote daarmee skoon.
Het 2 jaar terug gesien hoe dit koperdrade uit n 308 loop haal,wat gereeld met n ander produk skoongemaak is.

Hallo Meerkat
Ek wil my nie as n kenner uitmaak nie, maar kan maar net vertel wat ek self ondervind het. Soos Danie .243 s?, het elke ou maar sy eie voorkeure. Ek het ook voorheen onderandere Robla gebruik, as ook n klomp ander produkte wat ammoniak bevat.
By die Noord Kaap ope verlede jaar het ek vir Willem Immelman en John van Safari & Outdoor ontmoet, en by dieselfde gastehuis op n plaas gebly. Na ons inskiet oefening, het ek my geweer goed skoongemaak, soos die gebruik met my is. Willem het ook sy geweer skoongemaak, en soos dit nou maar is, het die gesprek toe by verskillende produkte gekom. Willem het my verseker dat die Boretech produkte die beste is wat hy nog ooit gesien het. Hy vra toe vir my om dit te probeer, nadat ek oortuig was dat my loop heeltemal skoon is met die Robla. Toe ek die Boretech Copper remover deur my skoon loop trek,en so paar minute los was ek geskok om die resultaat te sien. Ek was onmiddelik oortuig.
Die proses wat ek volg is eenvoudig. Ek trek eers n bore mop so paar keer deur, wat goed nat is met die Elliminator, om die ontbrande dryfmiddel te neutraliseer. Ek los dit so 10 min in, en stoot dan n skoon lappie deur , so 4 maal. Dan neem ek weer die mop met Copper remover, stoot hom so 4 tot 5 keer deur, en laat dit ook staan vir so 10 min. Ek neem dan n nylon borsel (nie koper nie), en trek hom so paar keer deur. Daarna druk ek skoon lappies deur tot hulle skoon uitkom. In die Stainless Steel lope, gebruik ek dan weer die mop wat ek uitgespoel het met water, en was die oortolige Copper Remover uit met die klam (water) mop. Dan druk ek weer droe lappies deur tot dit skoon en droog uitkom. Laaste druk ek n olie lappie so 3 keer deur om die loop te olie.
Voor ek skiet, druk ek so 4 tot 5 skoon lappies deur die loop, en skiet
Ek gebruik Kano Kroil olie daarvoor.
Ek het vir die eerste keer in my skiet loopbaan agtergekom dat ek eers so paar "foulers" moet skiet nadat ek goed skoongemaak het. Dit is vir my ook n bewys oor hoe goed die produkte werk. Nog nooit voorheen met al die ander produkte wat ek gebruik het, was dit nodig nie. Wat ek ook opgemerk het, is dat ek geen rooi neerslg (koper) meer sien as ek voor by die loop inkyk as die son hom reg vang nie, nadat die geweer skoongemaak is.
As ek weet dat ek kort na die skoonmaak moet gaan jag, of n kompetisie skiet, gebruik ek eerder gewone Nitro solvent om in die loop te los, ipv die Krano Kroil olie, aangesien ek agtergekom het dat dit die groot oorsaak is van die verskil in POI voordat die loop weer bietjie ge "foul" is.
M98 wat plaaslik vervaardig word werk ook baie goed, en ek is oortuig dat dit dieselfde chemiese samestelling het, aangesien dit dieselfde voel op jou hande en ruik, en werk net so goed.
Dit werk beslis goed, kyk maar na die groepe wat Johannic ook op die forum skiet met sy .243, en hy gebruik ook Boretech se produkte. Dit verwyder die koper chemies uit die loop.

Re: Loopskoonmaak
Hier is n vraag,
Nadat n loop met n produk skoon gemaak is wat die koper uit haal, vat dit dan eers n paar skote om die loop in te skiet? Of is hy dan reg soos hy daar staan?

Marius.
Dit verskil maar van geweer tot geweer. Jy sal moet toets om uit te vind.
My 243 se eerste skoot uit 'n koue skoon loop val altyd effens regs en laag terwyl my 308 weer op die nommer is - skoon loop of-te-not.
MAAR ek moet darem noem dat die 243 my langafstand roer is terwyl ek nie sommer die 308 gebruik om ver te skiet nie - ek kom nie so mooi reg met die gradeboog nie!
Mooi gaan.

Re: Loopskoonmaak
Thought this may be interesting;
"I've spent the last few months trying to get a better understanding of what a barrel break-in process is and how to properly clean a rifle. What to do and what not to do.
I've spent a lot of time on this board, the BR board and other shooting boards listening to members and what works for them. Conclusion, what works for some, doesn't work for others. Being an engineer in the telecommunications field, when it's broke or you don't understand something you go back to manufactures specs and schematics. So that's kinda what I did on this subject.
I've talked with 4 metallurgist and 3 barrel manufactures (Rock Creek, Hart and Shilen), on the subject. From a scientific point of view, they all said and agreed to pretty much the same thing.
First, barrel break-in processes keep them in business. This shoot and clean, shoot and clean every round or few rounds break-in process only damages your brand new match barrel. Think of a car engine for a moment. Why do we use oil in the engine? To prevent metal-to-metal contact and reduce friction between two metal surfaces. Your barrel is no different from the engine. Mike Rock at Rock Creek barrels gave me the most detailed explanations on barrels and ballistics. Mike has his degree in metallurgy; he was also the chief ballistics engineer for the Army for many years at the Aberdeen Proving grounds. Stan Rivenbark was one of the top ballistic engineers for Raytheon before he retired in the 70's and also has a degree in metallurgy. I also talked with two local metallurgists here in North TX. I confirmed my findings with each person to see if they agreed or disagreed. Conclusion, they all agreed with each other's assessments.
When Mike worked at Aberdeen proving grounds, the Army used high speed bore videos with mirrors, thermal imaging and computers to analyze any and everything that happens when the firing pin hits the primer and the round goes off. When the primer ignites there is enough pressure to move the bullet forward into the lands. The bullet then stops. As the primer ignites the powder, more pressure builds moving the bullet forward where it can stop again. Once there is enough pressure from the round going off, the bullet is moved down out the barrel. All of this happens in nanoseconds (billionths of a second). Your bullet starts and stops at least twice and sometimes three times before it leaves the barrel. This is fact.
If you clean every round or every few rounds during your barrel break-in process or clean your rifle so well after shooting that you take it down to the bare metal, you've created a metal-to-metal contact surface for the next time you shoot the gun. So what's the problem with this you ask? Just like your car engine, metal-to-metal contact will sheer away layers of metal from each surface. So if your bullet is starting and stopping two or three times as it leaves the barrel, that's two or three places for metal-to-metal contact to happen as well as the rest of your bore. The use of JB's and Flitz can and will take you down to metal-to-metal contact. For all intents and purposes, JB's and Flitz are not the most ideal products for cleaning your rifle.
According to Mike Rock, and the other barrel manufactures agreed, all you need to avoid this metal-to-metal contact is a good burnish in the barrel. Shilen, Hart and Rock Creek will all void your barrel warranty if you shoot moly bullets and for good reason. This is not to say that moly is necessarily bad for a barrel, but it is when applied to bullets. There is no way possible to coat a bore with moly bullets. The bullet contact surface in the barrel is only so big. But when your round goes off, moly comes off the contact surface of the bullet in the throat area of the rifle and is bonded to the barrel due to the excessive heat and pressure. We're not talking coated or adhered to, we're talking bonded, d**n near permanent. With this, some of the jacket coating comes off the bullet. Follow this up with another round and you've now embedded the copper jacket between layers of bonded moly. This is the beginning of the black moly ring, which ruins countless barrels and is so hard; it can hardly be scraped off with a screwdriver's corner edge. This is what happened to a new Shilen SS select match barrel I had to have replaced with less than 400 rounds through it. I can't talk for Fastex as I don't or none of the folks I talked to knew enough about the product to comment on it. When I talked to Mike about my new barrel and the barrel break-in process, this is what he had to say. He first hand laps each barrel with a lead lap. He then uses two products from Sentry Solutions, a product called Smooth Coat, which is an alcohol and moly based product. He applies wet patches of Smooth Coats until the bore is good and saturated and lets it sit until the alcohol evaporates. The barrel now has loose moly in it. Next he uses a product called BP-2000, which is a very fine moly powder. Applied to a patch wrapped around a bore brush, he makes a hundred passes or so through the barrel very rapidly before having to rest. He repeats this process with fresh patches containing the moly powder a few more times. What he is doing is burnishing the barrel surface with moly and filling in any fine micro lines left by the hand lapping. He then uses a couple of clean patches to knock out any remaining moly left in the bore.
With the barrel burnished with moly, this will prevent any metal-to-metal contact during the barrel break-in process. My instructions for barrel break-in were quite simple. Shoot 20 rounds (non-moly bullets) with no cleaning, as this will further burnish the barrel. Done! Now shoot and clean using your regular regimen of cleaning and if you have to use JB's or flitz type products, go very easy with them, or better yet avoid them. Never clean down to bare metal. He said most of the cleaning products do a great job, don't be afraid to use a brush and go easy on the ammonia-based products for removing copper fouling. Basically don't let the ammonia-based products remain in the barrel for long lengths of time.
Well that's the long and skinny from the scientific point of view on the subject. If you're ever in doubt about the real condition of your barrel, take it to someone who has a bore scope and even better if someone has a bore scope that can magnify the view. You may be surprised at what is really going on in your barrel.
I'm sure this will spark a debate here and there, but that's good thing. The more information we have, the better off we'll be."

If you clean every round or every few rounds during your barrel break-in process or clean your rifle so well after shooting that you take it down to the bare metal, you've created a metal-to-metal contact surface for the next time you shoot the gun. So what's the problem with this you ask? Just like your car engine, metal-to-metal contact will sheer away layers of metal from each surface. So if your bullet is starting and stopping two or three times as it leaves the barrel, that's two or three places for metal-to-metal contact to happen as well as the rest of your bore. The use of JB's and Flitz can and will take you down to metal-to-metal contact. For all intents and purposes, JB's and Flitz are not the most ideal products for cleaning your rifle.
According to Mike Rock, and the other barrel manufactures agreed, all you need to avoid this metal-to-metal contact is a good burnish in the barrel. Shilen, Hart and Rock Creek will all void your barrel warranty if you shoot moly bullets and for good reason. This is not to say that moly is necessarily bad for a barrel, but it is when applied to bullets. There is no way possible to coat a bore with moly bullets. The bullet contact surface in the barrel is only so big. But when your round goes off, moly comes off the contact surface of the bullet in the throat area of the rifle and is bonded to the barrel due to the excessive heat and pressure. We're not talking coated or adhered to, we're talking bonded, d**n near permanent. With this, some of the jacket coating comes off the bullet. Follow this up with another round and you've now embedded the copper jacket between layers of bonded moly. This is the beginning of the black moly ring, which ruins countless barrels and is so hard; it can hardly be scraped off with a screwdriver's corner edge. This is what happened to a new Shilen SS select match barrel I had to have replaced with less than 400 rounds through it. I can't talk for Fastex as I don't or none of the folks I talked to knew enough about the product to comment on it. When I talked to Mike about my new barrel and the barrel break-in process, this is what he had to say. He first hand laps each barrel with a lead lap. He then uses two products from Sentry Solutions, a product called Smooth Coat, which is an alcohol and moly based product. He applies wet patches of Smooth Coats until the bore is good and saturated and lets it sit until the alcohol evaporates. The barrel now has loose moly in it. Next he uses a product called BP-2000, which is a very fine moly powder. Applied to a patch wrapped around a bore brush, he makes a hundred passes or so through the barrel very rapidly before having to rest. He repeats this process with fresh patches containing the moly powder a few more times. What he is doing is burnishing the barrel surface with moly and filling in any fine micro lines left by the hand lapping. He then uses a couple of clean patches to knock out any remaining moly left in the bore.
With the barrel burnished with moly, this will prevent any metal-to-metal contact during the barrel break-in process. My instructions for barrel break-in were quite simple. Shoot 20 rounds (non-moly bullets) with no cleaning, as this will further burnish the barrel. Done! Now shoot and clean using your regular regimen of cleaning and if you have to use JB's or flitz type products, go very easy with them, or better yet avoid them. Never clean down to bare metal. He said most of the cleaning products do a great job, don't be afraid to use a brush and go easy on the ammonia-based products for removing copper fouling. Basically don't let the ammonia-based products remain in the barrel for long lengths of time.
Well that's the long and skinny from the scientific point of view on the subject. If you're ever in doubt about the real condition of your barrel, take it to someone who has a bore scope and even better if someone has a bore scope that can magnify the view. You may be surprised at what is really going on in your barrel.
I'm sure this will spark a debate here and there, but that's good thing. The more information we have, the better off we'll be."

Tx for the informative piece, quite interesting I must say. I'm not about to argue the points you raised. In my own experience I am shooting F-class and hunt quite extensively for the last 12 years, and have shot out a few barrels as well. I follow the break-in procedure as prescribed by Krieger on their website, as well as Border barrels from Scotland, as well as the disciplines taught to me by Chris van Niekerk. They all recommend JB paste, and are quite persistent on the break-in process.
I am not guessing about the state of my barrels, I use a borescope after every cleaning session.In addition, I actually do round counts, not guessing how much I have thrown down the barrel. I must therefore state that I do not agree with the opinions of the people mention in your post, my eyes tell me something rather different for the last 12 years.
The Moly issue has been discussed somewhere on the forum, in my experience not a bad thing, and certainly not as bad as Mike Rock explained, but also not something that will give you a 50% increase in barrel life and performance, closer to 10-12%.
But, and this is a big BUT, as you have mentioned, this subject boils down to an "each to his own" situation, I can therefore not discredit the information in your post, I am by no means qualified to do that, it's just that I use different methods/products/procedures, and it works for me.
Thanx in any case, some interesting points that were raised, and well researched.
