dankie

Hello Boeta
My 1c. Het sopas my 243 Tikka M595 (nou AI) met nuwe loop (Pacnor SS SM) ingeskiet, wel amper. Trek by 180skote (begin ook nou toemaak) maar fireform nog doppe (darem op jakke en papier)..
Daar's baie ouens wat jou seker beter kan raad gee (veral die met die bore scopes, wat definitief sy plek het), maar ek dog ek noem maar net my dril.
Ek het glad nie gepeuter met die dinge soos vooraf poleer ens. ens. nie.
As ek dit kort kan laat klink, klink dit so:
Skote 1-10 maak skoon tussen elke skoot. Doen dit deeglik en vat jou tyd, met genoeg lappies. Weet nie wat se skoonmaak middel jy gebruik nie, heeltemal 'n nuwe onderwerp!
Skote 11-30 maak skoon tussen elke 3-5de skoot (hang ook maar af van jou spoed en kruit seker)
Skote 30-50 maak skoon na elke 10de skoot
Skote 50plus maak mens maar skoon afhangende hoe gereeld/baie mens skiet. Ek werk maar so op 20-30 op die 6mm. Elke ou het maar sy manier en omstandighede.

Sjoe, ek hoop nou nie ek praat teveel tjol nie.

ns. probeer maar gerus maar die premium middels soos Kriol, Hoppe's, Shooters choice. Dirk hulle verkoop ook 'n goeie doepa. Ek's nou af van die M98.

Hi Boeta

Hierdie geleen op KRIEGER se site.

BREAK-IN

With any premium barrel that has been finish lapped -- such as your Krieger Barrel --, the lay or direction of the finish is in the direction of the bullet travel, so fouling is minimal. This is true of any properly finish-lapped barrel regardless of how it is rifled. If it is not finish-lapped, there will be reamer marks left in the bore that are directly across the direction of the bullet travel. This occurs even in a button-rifled barrel as the button cannot completely iron out these reamer marks.

Because the lay of the finish is in the direction of the bullet travel, very little is done to the bore during break-in, but the throat is another story. When your barrel is chambered, by necessity there are reamer marks left in the throat that are across the lands, i.e. across the direction of the bullet travel. In a new barrel they are very distinct; much like the teeth on a very fine file. When the bullet is forced into the throat, copper dust is released into the gas which at this temperature and pressure is actually a plasma. The copper dust is vaporized in this gas and is carried down the barrel. As the gas expands and cools, the copper comes out of suspension and is deposited in the bore. This makes it appear as if the source of the fouling is the bore when it is actually for the most part the new throat. If this copper is allowed to stay in the bore, and subsequent bullets and deposits are fired over it; copper which adheres well to itself, will build up quickly and may be difficult to remove later. So when we break in a barrel, our goal is to get the throat polished without allowing copper to build up in the bore. This is the reasoning for the "fire-one-shot-and-clean" procedure.

Barrels will vary slightly in how many rounds they take to break in because of things like slightly different machinability of the steel, or steel chemistry, or the condition of the chambering reamer, etc. . . For example a chrome moly barrel may take longer to break in than stainless steel because it is more abrasion resistant even though it is the same hardness. Also chrome moly has a little more of an affinity for copper than stainless steel so it will usually show a little more "color" if you are using a chemical cleaner. (Chrome moly and stainless steel are different materials with some things in common and others different.) Rim Fire barrels can take an extremely long time to break in -- sometimes requiring several hundred rounds or more. But cleaning can be lengthened to every 25-50 rounds. The break-in procedure and the clearing procedure are really the same except for the frequency. Remember the goal is to get or keep the barrel clean while polishing out the throat.

Finally, the best way to break-in the barrel is to observe when the barrel is broken in; i.e. when the fouling is reduced. This is better than some set number of cycles of "shoot and clean" as many owners report practically no fouling after the first few shots, and more break-in would be pointless. Conversely, if more is required, a set number would not address that either. Besides, cleaning is not a completely benign procedure so it should be done carefully and no more than necessary.


Mooi bly

Ek gebruik maar "Carberator Cleaner" om die kruit uit te haal en dan Shooters Choice of J-B paste.  Altwee werk goed, die CC ding het ek op n Amerikaanse site raakgeloop en werk heel goed.  Gebruik lankal ook nie meer borsels nie, net lappe.

Sien onder Pacnor se aanbeveling.
Barrel Break-In and Cleaning Techniques
Thanks for purchasing a barrel from us!

For best results, of course, it is necessary to 'season' it and use proper cleaning equipment. We like the Dewey coated rods, a good bore guide, copper/bronze brushes and cotton flannel patches, the appropriate size to keep that jag and rod in the middle of the bore. You will need a good bore solvent, like KG 3, Shooters Choice or CR-10 to loosen the fouling, followed by a scrubbing with Holland's Witches Brew or KG 2. After cleaning, nullify the solvents with rubbing alcohol and patch dry. Finish with Tetra Gun Oil, KG 4 or Holland's Bbl Break-in Fluid. Never shoot a dry bore as this will greatly promote copper fouling.

Chris recommends:

Shoot one, clean, for first ten rounds; shoot three, clean, for next thirty rounds; shoot five, clean, while working up load. Allow bbl to cool to the touch before testing a new load to avoid unnecessary throat erosion.

Ja3, Rainie

Is dit werklik nodig om n loop in te breek/skiet. Die ouens hier op die forum vertel van die beste maniere om lope skoon te maak en alles uit te haal behalwe die "lands". Ek weet darem nie. Tip Ex skiet op sy beste as sy loop vuil is en Cutex gee nie regtig om wat ek met haar loop doen nie. Al2 roere groepeer onder n duim op 200m. Vorige lope op die gewere het baie skote geskiet voor hulle klaar was en hulle was ook nie gepamperlang nie. 

Ek is maar stupid met die roere, dalk kan die slim ouens vir my se hoekom waarom en wat.....?

Hoop dit gaan goed.
Ek hoor jou. My 30-06 soek op die oomblik nie minder as 16 skote nadat ek koper/koolstof uitgehaal het voordat hy weer groepeer nie! ...en die loop is nie uitgeskiet nie.
Ken ook 1 of 2 ander ouens met 300's wat dieselfde ondervind.
Ek dink mens moet nie meer as 50 skote sommer skiet sonder om skoon te maak nie (in 'n gegewe tydsperiode/weersomstandighede ens.). Teveel skoonmaak kan meer nadelig wees as te min, mens moet tog die geweer leer ken ook...
Met die loop in-skiet voel ek persoonlik mens wil tot in 'n mate 'n geleidelike slytasie inbring en vreemde aanpaksel uitskakel in die begin van 'n nuwe loop.
Mens is geneig om te vergeet dat giroskopiese stabiliteit van die projektiel eers werklik ontdek is met die inbring van groewe "rifling", om die verswakking in akkuraatheid teen te werk a.g.v aanpakking in die loop.

Ek hoop nie ek los 'n bom nie..

Dit lyk na interresante storie

Het julle in die Magnum gelees van die nuwe metode van "rifling" wat die pelletgun manne nou na kyk. Waar net die laaste 2 duim van die loop van buite gepress word,  om binne die loop te vervorm,  om spin op die projektiel te sit.  MAW smoothbore tot die laaste 2 duim en dan vervorm,  geen groewe...dink net hoe lank gaan lope hou,  het nie "lands" om uit te brand nie.

Weet iemand waar mens nog inligting hieroor kan bekom?

Jou akuraatse skoot is die eerste een deur die loop.Waarna kyk jy met 'n boorscope? Of die groewe se hoeke mooi skerp is.
Die inbreek van lope is begin sodat die loop makers meer lope kan verkoop .As 'n benchrest skut 700 skote uit 'n loop kan kry en hy gebruik 50 om die loop in te breek het hy net 650 skote voor hy 'n nuwe loop moet opsit.Dit maak ekonomies baie sin maar het prakties geen waarde vir 'n "custom" loop nie.

Halo Ja3

Ook nou groen geraak??

Dit is hoogs aansteeklik.

Hallo Jaracal

Seker min tyd gehad vandag om aan lope inskiet te kon dink....

My dag was ook uitstekend. Sal later meer kommunikeer.

Nou nie iets met lope inskiet te doen nie, alhoewel die jong getroudes wel by die post kan baat...
So van slytasie gepraat.
