Every time I shoot my Gamo .177 pellet gun I get
a small waft of smoke coming out of the muzzle. I cleaned
the bore very well, but it still happens.

Is that "smoke" actually vaporized lead????

Please advise. vty Pete GOA/NRA

A small amount of smoke is normal. When undergoing rapid compression
your air chamber will generate heat sufficient to cause oil to smoke. If
the
improper oil is used, your rifle could actually diesel, not particularly
good
for the gun if it occurs too frequently. Use good high flash point oils
made
specifically for spring compression airguns.

Couple possiblities.

I wouldn't think vaporized lead. Are the pellets coated with anything
which could be scrubbed off during the pellets' passage down the bore?

Is this an air gun or a CO2 gun? If compressed air, it could be
condensing water vapor, sorta like a jet's con-trail, especially if it's
happening in a very high-humidity setting. (I guess.)

What about some sort of solvent or oil which could be somewhat ignited
by the pellet's passage down the bore?

Dunno ... but water vapor seems the most likely.

Try it without a pellet. My guess is that it is water vapor.

nope, i assume the gamo .177 pellet gun your talking a bout is a CO2 operated
pistol. if so the "smoke" you are seeing is just left over compressed Co2, if
it's a phnumatic (sp) guns tend to not have this "smoke". the compressed co2 is
harmless unless you use it so much indoors with poor ventalation that the co2
out does the oxygen

No, that's actually a bit of vaporized oil. I'm not sure if it is simply
atomized by the rush of compressed air going past or what, but I have
noticed the same thing in my pellet pistol. The pellet gun does not have
enough heat (because it burns nothing) to vaporize the lead of the
pellet. --Murphy

If it disappears almost immediately then the "smoke" you see is probably
water droplets formed by the rapid cooling of the expanding gases dropping
below the dew point.

no it is oil in the compression chamber. after 50 or so shots it will stop
smoking. remember it takes just a drop or two to lube it. any more and your
just blowing smoke.

I believe it is smoke caused the same way a diesel engine produces smoke.
A small amount of oil in the tube is put under pressure by the piston and
smoke is produced.

No, it is vaporized oil. Not uncommon with pellet guns.

It's called dieseling it's the oil on the pellets igniting due to the pressure
and friction . Nothing to worry about.

Pete,
I assume we're talking about a single stroke pump here? Something like a
Beeman R-1.
If so that smoke is from oil in the pnuematic tube. It's like a car engine that
fires from compression alone. Dieseling is the term for it, have seen it in
short barreled carbines and pistols of sufficent power. I'm sure that this is
what is going on with your El Gamo. Try firing a few felt cleaning pellets
though it to remove all traces of oil from the barrel before firing.
In any case it's not lead or harmful to you or the gun.
Hope this puts your mind at ease, keep shooting!

If your pellet rifle is CO2 powered, it may be semi-vaporized liquid
CO2. If it happens more on colder days than warmer, that's probably the
ticket. I notice the same thing from some of my short-barrelled CO2
pistols if I tilt the gun upwards between shots(liquid gets in the
valving?)

On the spring-pneumatic types, it could be the moisture in the air
condensing, much like on an air compressor (That's what the water drain
on the tank is for).

When SCUBA tanks are filled, the compressors have to qork quite hard to
compress the air through several dessicant layers to be sure it is "Dry"
in the tank, otherwise the tank and various connecting pieces can
corrode or malfunction from condensation.

Could be wrong about this, but I think the "smoke" might be oil
mist from the lubricated pellets. I used to see the same thing when
shooting my Crosman guns. It smelled like oil. M.Rap.

Of course it is. The air pressure in your air rifle induces a temperature well
above
not just the melting point of lead, but in reality results in a vaporization of
the metal
in question. Since it is lead that is being vaporized, it generally falls
straight down
from the muzzle - the weight / mass, is just to much. You should wear steel
toes
to protect yourself from this heavy vapor from hitting your toes. This also
explains
that none of your projectiles (bullets) ever hit the target. They are
vaporized prior
to exiting the muzzle. Those lead vapor guns in general require a special EPA
license, one of which I am sure you are in possession of?

All kidding aside - have you considered the fact that the manufacturer, in
order
for your arm to work properly, has squirted a lot of oil into the plunger /
pump
system, and you are just blowing out a bit of vaporized oil?

Humoristically,

Klaus

Nothing to worry about. Be sure that you are not overlubricating

Certainly not vaporized lead. Closer would be air compressed then
rapidly expanded would produce water vapor or fog.

Very doubtful that what you are seeing is lead, Peter. While there will
invariably be some lead dust, it would be too small to create a visible
cloud.

What you are seeing is the smoke from the burning of the cleaning oil.
Air guns create a lot of heat when they compress air. And they typically
ignite any oil that is in the chamber. This is called, 'dieseling', just
like a diesel motor operates. If excessive oil is left inside the air gun,
it can actually damage the gun by creating excessive pressures.

I would recommend that you thoroughly dry your chamber and barrel before
shooting. Some companies make felt pellets that you can shoot through your
gun to help dry it out.

Also since airguns depend on their seals, make sure you only use solvents,
cleaners and oil recommended by the manufacturers. Many oils and solvents
will harm the seals and ruin the air gun.

If you have been leaving any lube when cleaning you could be seeing a
"desiel" effect, especially if the air rifle is a 440 or 880 that
pushes out at ~1000fps. You should be very careful about residue oil
or lube in a high compression air rifle since the desiel efferct is a
form of explosive detonation that th erifle is not meant to have.

Not likely. Chances are, it's oil being vaporized. No idea of the source of
the oil in YOUR gun, but it happens commonly.

More than likely, it's vaporized oil. The more you clean it, the more

Spring powered airguns should not be fired without a pellet. It allows
the piston to slam into its stop with too much force. - CW

If it's a spring-piston type gun, air temp may reach 2000 degrees momentarily
as the piston slams forward in compression. If there's even tiny traces of
lube oil in there, it can vaporize and diesel (combust), producing a puff of
white smoke with a distinctive odor. In some cases, severe dieseling (or
detonation) may damage the gun--which is why it's important to lube sparingly
and to use only silicon-based piston oil. Never fire a spring piston gun w/o a
pellet--this causes the piston to slam into the front of the compression
chamber, and may damage the gun (normally the piston "bounces" on the air
column trapped behind the pellet before coming to rest).

If it's a CO2 or air-driven pneumatic type gun, dieseling doesn't happen. What
you're seeing is probably water vapor.

I missed the first post but I think you are discussing a effect called
"deseiling" Basically the oil in the main compression chamber of the gun is
heated to the flash point. This causes the smoke. This a NOT a good thing for
your gun. It can destroy the main seal and/or spring. This will ruin power
and accuracy. NEVER use 3 in 1 oil or anything like it on airguns. It will
ruin them. Only use silicon based oils like the stuff Beeman sells. You
should almost never have to put oil in the chamber. IF you hear the seals
squeeking when you cock the gun then put in maybe 1 or 2 drops tops. Otherwise
just leave it alone. Wipe the outsides down and that should be all you need to
do.

If you are interested in more information on airguns you could try The
Airgun Letter web site at: http://www.airgunletter.net They are a great
place to start. Reviews on airguns, newsletter, dealer and repair station

Boyles Law at work, or PV=nRT. When that compressed air (or C02) hits the
relatively cool ambient air, the moisture in it condenses, like your
breath in front of your face on a cool day. That and/or vaporized
oil/lube on the pellet(s).

That effect is a new one on me. Does it have anything to do with the German
inventor of an internal combustion engine type, commonly refered to as
the Diesel engine?

Or is it a special effect, a la Hollywood?

the Gamo your talking about is dieseling. BUT the dieseling is occuring in
the compresion chamber and will destroy your spring if done to much. Just
don't oil it but every 1500 shots with only airgun oil and you'll be ok. As
for pump or Co2 guns it's water vapor.
