Bore cleaner questions
« on: January 23, 2009, 08:06:26 AM »
hey guys and gals I have a mosin nagant 91/30 and a jap arisaka carbine and both bores are pitted and I know I can't fix that but was wondering what was the best way to make sure all the copper fouling is out of the barrels.  Any secret remedies and formulas anyone wants to share.  I tried the foaming stuff and I used almost an entire can and its still coming out blue.  Thanks if advance for any advice.

JB bore paste or Flitz metal polish.  I put a felt patch around a bristle brush and use this to scrub the bore good. (it could take 30, 40, or even more passes to clean a dirty bore) After I have scrubbed the barrel good, I run a couple patches of hoppes #9 thru and check for crud.  The first couple will be removing polish or bore paste residue.

After bore is scrubbed and cleaned with the Hoppe's.  I clean the chamber area with a bore mop and clean the barrel crown.  Everything should be clean so this is when I run the first dry patch to check my progress.  When I get a dry patch to come out clean, I am done and ready to follow up with an oil patch then put the gun away.

If shooting corrosive ammo, start with hot water patches so the corrosion stops.

Wipeout foaming bore cleaner. Spray it in let it set a while the patch it out, repeat if required. This stuff flat works better than anything I've ever tried. 8)

Thanks gonna try this week to get them clean noticed that the nagant was smooth for the first couple of inches at the muzzle that gonna hurt accuracy alittle  :)  Might have to get the barrel shortened from the 27.5 to like 24 or 22.  More manageable but louder.  And I'll lose my front sight so I guess gonna have to think about this for a while.  Thanks again.

You can use an electric bore cleaner. I have tried it and it is effective beyond belief. I had a sewer pipe barell that turned into a shiny bore. I did it with a steel rod, electric tape, two wires, and a 9V battery, and i plugged the muzzle with the cut-off finger from a rubber glove and tape.

The last 5 or 6 inches of the bore seem worn by cleaning with the steel rod. You can have a gunsmith counterbore: he will drill a 8.5-9 mm (or such) hole along the worn portion of the bore. That way, you could still keep the front sight. Actually, a longer barell allows you better aiming because of the longer sight radius.

First clean it with Hoppes and patch it dry.  The patch it wet with Windex with Ammonia, let it sit, scrub it with a brass bristle brush and patch dry.  The Ammonia lifts a incredible amount of crud and old copper from bullet jackets.  Then, if you want, use some of the other products the guys mentioned.

I have used this process any number of times and the results make me very happy.  As for worn throats and muzzles - they might not affect accuracy as much as you think.  You will always have some throat erosion and most likely a lot of muzzle wear but the rifles may still shoot accurately.  Clean those babies up first and shoot them before you decide on any gunsmithing work, you may be a lot happier with the results before you start having work initiated.  

Sometimes pitting does not affect the accuracy, it just allows crud build up but bore lapping can help accuracy problems from pitting if that is the culprit.  jmtcw.
