INOX / WD40 coated inside Barrel, first couple of shots way off

[tridiumk]

i spray INOX (not sure if you have that in America) which is like WD40 down the barrel of my DTA SRS A1 338 LM after i shoot it and put it away, i dont clean the barrel between shooting.... just coat it to protect it.

I dont clean out the barrel of the lubricant before shooting, i just shoot it clean of it...

My first 2 or even 3 shots are waaaay off sometimes, like i'm talking 6 inches at 200 yards. second shot also goes astray, 3rd shot is usually close, then they are bang on 0.5 MOA consistently after that.

I got to thinking, Cold Bore, or WD40... or both ?

Could the choice of Spray inside it perhaps last a couple of shots before getting the barrel consistent?

Are you patching it out before shooting it?

 

[Niles Coyote]

Anyway you look at it this is not a good idea... at least patch the barrel before shooting. And yes, a lubed bore will shift its impact point.

 

[tridiumk]

Are you patching it out before shooting it?

Nope, just shoot that puppy dry.

 

[BLDTYLRY]

Since you are spraying that stuff down the barrel and not patching it out for the first shot you should know that you are increasing the chamber pressure and can damage you and/or your equipment.

Toss the INOX and any WD40 you have laying around over the nearest fence or use it on a padlock or something else already rusted.
It is really a penetrating oil, not a preservative.

I use a couple of drops of a good gun oil on a patch, stroke it down the barrel a couple of times and then follow with 2 dry patches. Before shooting a couple more dry patches and my cold bore shots are within my ability to hold a group. Note: I only do this if the gun is to be stored for a couple of weeks or so. Shorter time I do nothing and I live in S. Florida with the attendant heat and humidity. At about 400 rounds after tomorrow's range session, I am expecting the bore to need a cleaning soon. I'll see how it shoots tomorrow.

WD40 is spray gasoline and belong nowhere near a rifle ! Just use a quality oil and always run a patch down it and a few dry ones after the oiled ones ! As mentioned ya do not wanta any extra oil in the bore as it will cause serious issues but ya do not want WD40 down it !

WD40 will collect moisture and one day your barrel will be full of rust.

 

[tridiumk]

okay sweet, good advice, thanks everyone !!! I will go back to putting Breakfree oil down it for storage...

The WD stands for "water displacement". How is it going to collect moisture ?

That's what I was wondering. WD40 is more like kerosene than gasoline- neither of which are good gun oils. WD40 is great from a gunsmiths point of view, they get plenty of business 'repairing' guns that are full of gummed-up WD40.

Make the switch to another oil and patch it out of the barrel before shooting. Your first rounds may still be off, but should be more consistent.

MAGUA, he is correct...the moisture it collects is from the tears of those misguided enough to use it.

A non shooting friend recently was left a suitcase full of old handguns from a distant relative who was a Sheriff in the 50's and 60's. 80% of them were were junk, but in among the group were three old K-22's, two K-38's and a really sweet old pre, War M&P, pre M-10.

ALL of them had been sprayed LIBERALLY with WD-40 (An ancient can IN the suitcase) and possibly sprayed every several years to "preserve" them. Then locked back up in the old suitcase and placed back on the shelf in the garage.

NONE of the Smiths would cock or function, a few wouldn't allow the cylinder to be opened. Even removing the grips so I could clean the guns up was difficult. The WD-40 seems to turn to VARNISH over time. Each revolver had to be soaked for a few hours with a liberal spray of KROIL to allow me to open them, remove the sideplate, etc.

WD-40 is great for a rusty lock, old hinges, etc. WHY people insist on using it on fine firearms simply amazes me.

RANT mode......OFF.

Went to buy a german luger that a guy had in a pistol case that he had in his safe and had not looked at in years, he said that it
should be in great shape seeing how he wiped it down with WD40 before he stored it.
Well it was a pile of rust with heavy pitting and pretty much worthless. Maybe it displace's water but not moisture.

 

[tridiumk]

I probably misguided everyone by saying INOX / WD40. I believe now having looked a little more into it, that INOX is very different... it is a completely clear oil, that doesnt leave that same yellow shit that WD does.

INOX sponsor the local pistol club here. I'll post up the back of the can for everyone to read, see what you think about it..

 

[tridiumk]

says "Contains no silicon, acid or acid forming ingredients, diselene or kerosine".

Anyway, point is, i need to clean the barrel before shooting it and not just blast it all out with a couple of rounds !

 

[Rattler56]

The only lubricant in the world with the special MX3 anti-corrosion, anti-moisture formula for the twenty – first century.

Had to look it up to see what you were talking about and it states anti-moisture, have no experience with it, however
seems to work for you.

Do yourself a favor and stop spraying whatever down the barrel. All that is needed is a small, very small coating of oil to protect the bore from moisture. I have nearly 50 guns in my collection and I shoot them all. Most I ever do is swab out the bore with a couple of drops of oil on a patch, followed by a couple of dry patches to remove any excess.l My precision rifle doesn't even get that. I may patch the bore if I have been shooting in the rain. The gun has a hand lapped barrel and a bore scope shows minimal copper fouling and just a bit of carbon fouling, which will attract moisture to some extent. A couple of passes with a dry patch handles that.

I am of the opinion that more guns have been worn out by over zealous cleaning than by actual firing. Your gun will tell you when it needs to be cleaned. Accuracy will fall off. In some cases dramatically in others gradually. This is where a data book can benefit you. Track and record every shot, including your calls. I used to poo=poo this until i got to be a better shot. It is really helpful.

See if you can find anything similar to Lock-Ease:

It's colloidal graphite in a petroleum distillate solution. A lot of shooters apply it after cleaning and leave it on to reduce the CBS's POI shift.
