...do I need to worry about that or do I just wipe them off and keep it well oiled? Mike Legistine actu quod scripsi?

While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down. 5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine. 6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle. 7.

White crusty stuff leaking out after a re-blacking job? It was hot-blacked right? | |||

Yes white crusty stuff...yes it was recently hot blued. Didn't happen until after the second range session. Both sessions were about 50 rounds. Mike Legistine actu quod scripsi?

Not good IMO bud, the caustic blueing salts have gotten in, either through pinholes in the brazing or by undermining the solder. Is the join brazed or tinned? Forgot to ask, what firearm are we talking about here? A friend had the same problem on a shotgun he had reblacked. His barrels were brazed and I don't know if it harmed anything but he is still, two years later, wiping away white stuff. I don't think soft soldered stuff would be hot blacked by any responsible gunsmith, it would probably fall apart... | |||

I don't think the barrel is soldered or brazed to the action. Bleed out of blueing salts is common after blueing. Scrub it off with a toothbrush and some Hoppes or wd-40 and keep an eye on it. It will soon stop. NRA Patron Life Member Benefactor Level | |||

It's common. The old guy, a chemical engineer, who use to do bluing for me 30 years ago use to spray everything down with a penetrant very similar to WD-40. It took care of the problem. You might pull the scope base and blow a little penetrating oil in on top of the barrel threads. Don't drive yourself crazy over it though. _______________________________________________________________________________ This is my rifle, there are many like it but this one is mine.

Had it on my hot blued 404 every so often for about 12 months and I take it that it is in the same place, that is, the barrel - action thread. I kept it wiped off and liberally oiled. Havent seen any now for a couple of years. Von Gruff. | |||

It wasn't boiled out enough after bluing, unless you pull the barrel, take the above gentlemens advice, just a mild aggravation really. | |||

 I didn't think it might be a rifle.... What about my friend's shotgun, is it just a cosmetic problem or should he be worried? | |||

It is a rifle and I will apply the above...especially pulling the scope base... Mike Legistine actu quod scripsi?

While a major pain in the butt as others say scrub it and oil it. A penetrating oil seems to work better. As usual just my $.02 Paul K | |||

Simply bluing salts that has weeped into the threads during the hot tank immersion. Usually a good 45 minutes or so in the hot neutralizing bath, followed by 30 minutes in the hot water bath, followed by a overnite soak in the water displacing oil tank will take it out. If a step or two of this procedure is ommitted, the salts stay and show up later! Most guys bluing do not go to this extreme as it takes 6 tanks in the setup, three of which are heated. I totally removed this problem by bluing with the barrel out of the receiver. Before the nay sayers jump in, yes, the barrel may be installed and properly torqued with the correct equipment and procedure without marring the bluing. You problem may be corrected by removing the barrel and thoroughly cleaning & oiling the threads, both in the receiver and on the barrel. | |||

Just a note...those salts can really raise cain with stock finish. I'd take the action out of the stock and check. Down the road, there will be some pretty nasty rust forming on the threads. Best bet would be to take everything apart and boil profusely. | |||

Yes, Yes, and Yes! Don't ask me how I know bluing salts will eat concrete. | |||

its a bit of salts left in the threads.. brake fluid, wd30, kroil, and a soft brush.. don't tough it, as it might burn you its called salt bloom, and its caustic opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Woodhunter and Duane are right on. I have ran a hot bluing operation many years. If the barrel receiver joint or any other joint in the gun has blumes (bluing salts creeping out) then the person running the hot bath operation did not boil the parts properly with nuetralizer and or clean water. I boil my work out with rain water at a hard rolling boil for 30 minutes, blow off with compressed air, then quickly submerge in ATF while parts are still hot and let soak overnight. I have never observed any creep after this treatment for quite a few years. You can also have your barreled action boiled out with the barrel still on it and the creep will cease if properly done. Stay away from tap water, use only distilled water or rain water or risk rust spots forming. I knew one man who did quite a bit of hot bluing for years and he insisted on boiling the parts out in motor oil. Yes BOILING oil! I never could convince him that bluing salts is soluble with water not oil. You could always recognize his work because it always had some bluing salts creep. How he has kept from burning the building down is a great mystery to me. Craftsman | |||
