Oversize bore brush stuck in barrel.

[243winxb]

Well, almost. I now measure the bore brush diameter with a micrometer before using it. Some marked 243/6mm are way* oversize. Almost had one stuck in my Rem 40X. Just seen same on another forum, but a .224" brush. https://www.shootersforum.com/black-rifles/

I always use a oversize brass brush.

Just be sure to pull or push it all the way through to the same direction. I get the brush good and wet with solvent and pull it through from the chamber. That way all of the gunk falls out the muzzle end and not into the action of the gun.

The only time I push the brush from the muzzle is with a worn brass brush when cleaning heavy copper fouling.

Pour some oil down the barrel, rethreaded your cleaning rod on the brush and push or pull the original direction. The softer brass metal will not harm the hard steel in the barrel although pounding on the barrel itself or a on a oversize steel rod is not good.

I use oversize brushes as well, especially on black powder. There are two kinds of brushes that I have found. The ones where the bristle-holding wire "threads" through the threaded end like a needle, and the ones that are crimped in. You have to be more careful with the former, since that leaves the cut end out at the barrel, but I have had the crimped ones come out mid-stroke.

For 243 win

A .248" bronze is ok. The bronze .260" is not. The nylon is .294" and oversize also. The bronze brush should not bend a steel coated rod. I dont think its a common problem, as the problem brushes came from the same online source. (To remain unnamed) Been cleaning 243's since the 1970s.

I got a 30 stuck in a 243 about 1" into the bore working from the chamber. I had to thread on a short rod section and use vice grips at a right angle to twist it back out. I felt lucky to have been able to get it out.

I use a 45 caliber brush to clean my 9mm pistols, it really scrubs the crap out of the bore.

I need to get some larger bore brushes to clean my 45 pistols.

Not guaranteed but worth a try: Twisting it while pulling or pushing it tends to collapse the bristles sideways, which breaks their grip on the bore. Withdraw or push through while maintaining that twisting motion to keep the bristles canted sideways.

Try that with a .38 revolver with a brush which is longer than the cylinder. Or with an auto with the slide locked back for a quick brush-out.

Fun.

BTDT. Both. Ya live, ya learn.

More guns, cameras, small boys and coffeepots have been ruined by excessive cleaning than any other single cause.

Never stuck a bore brush, but cleaning patches, well that's another story.

1) Scrub back and forth; really gets the bristles down into the rifling
2) Wooden dowels; lots and lots of wooden dowels
3) Long aircraft drill bits; basically no different than a cleaning jag

You're welcome.

I am going to disagree and say never reverse a brush in the bore. Push it all the way through, bring it back all the way out.

The brushes only need to be slightly over groove diameter. Brush casually. Let solvents do most of the work. When the brush gets loose, toss it. No steel, no nylon.

I have put too big of a patch on a jag before and when it got tough right away have just prayed I got it all the way through without sticking it or damaging a nice rod.

Some marked 243/6mm are way* oversize.

What brand brushes were they?

 

[230RN]

Ah b'leeves that barnbwt forgot to put a in his post.

And he also forgot about firing another round to clear the bore.

Walkalong, the oversize one is Pro-Shot Benchrest Quality Rifle Bore Brush Bronze. Dewey was out of stock when i placed an order. The nylon one is Dewey and is not as tight as bronze.

 

[243winxb]

223 caliber

Just measured a Pro-shot item #22CF .223 cal benchrest bronze brush. Come in at .246" Seems to be also on the large side.

Barnbwt you forgot to mention ammonia based copper solvent in chrome lined bore. Otherwise you are the patron saint of fails.

Huh. I'm not familiar with that one, not having any chrome lined bores. What's the effect?

If there is a crack in the chrome that copper solvent can get in underneath. Most chrome is applied over a copper substrate coating. When the copper is dissolved, the chrome starts coming off. No bueno.

I worked in a plating shop for five years, we NEVER plated hard chrome over copper. Are you thinking of the triple plated decorative chrome cooldill?
Decorative chrome is chrome over polished nickel over polished copper extremely time consuming work done for auto restoration on chromed trim and such. I cannot see this being done on the bore of a rifle. Even without the polishing.
