cz527 in 7.62x39 chamber cleaning

[86304]

how do you guys clean the chamber (not barrel ) on your 527's in 7.62?
bronze or nylon brushes? what size? solvents?
been shooting sealed primer GT and just wondering how to best clean the chamber.
thanks for your sage advice.

I don't how sage my advice is, but there is a lot of sagebrush out here...
A bronze bore brush works fine, use on for 9mm or 40SW, pull the bolt and run it up throught the back of the action straight in. Solvents I use are either Weapon Shield CLP, or Hoppes Number 9 for serious dirt.

thanks, that's what i'll do

I use an AR chamber brush plus Ballistol.  Insert from the rear, a couple of quick turns and every thing should be golden then do the barrel.  I use Wolf 123 grain steel exclusively.

i've got an AR chamber brush that i'll give a try with the ballistol.

I typically run a wet patch of Ballistol and let it sit for a while (10 or 15 minutes).  Then I use a chamber brush with more Ballistol followed by dry patches to finish the job.  Ballistol does a fine job of getting "under" fouling if you let it soak for a spell.

do you use the ballistol full strength or cut down with water?

I always use Balistol full strength.  I guess I'd dilute it for cleaning a black powder barrel.

When you clean the barrel, pull the patch/brush from the chamber to the muzzle.  That way the crud you are trying to remove goes out the end of the barrel rather than getting pushed back into the chamber and receiver.

At least it'll be quicker/easier to clean the chamber.

I haven't brushed a chamber in years.  I just put the solvent on the patches and pull them through the chamber/barrel from the receiver towards the muzzle.  I'll usually spin the patch around in the chamber a few times before pulling it to the muzzle with the cleaning rod.

I don't get tore up about coated/non-coated rods.  I don't use jags (because I don't push anything through the barrel, from either end.

Pushing a jag/brush/patch & tip through the barrel means you put a compressive force on the rod - which causes it to bend and rub the lands as it passes through.  The bore guide a lot of people recommend will not keep that rod from contacting the lands if you push brushes/patches through the barrel.

If you pull the brush/patch through the barrel from the chamber end towards the muzzle and do it slowly you put the rod in tension and it will stay straight and not contact the lands unless you pull it sideways and make it contact the lands.

This has worked for me for about 40 years or so.
