how many shots have you taken with it since new? it might still be dieseling... take a shot then open the barrel and look thru the bore (from the breech side!!!) see if you can see the light at the end of the tunnel.if you can't blow in it and you'll see the smoke come out of the other side. it will tell you if there is still residual oil igniting upon firing the rifle.

hey ok i fired right around 500-700 shots uhm and i smell a really bad stench after i fire but it just stoped smoking to days ago it quit cold turkey ha sorry bad joke

that is the best to quit. do me a favor, get a cleaning kit and run a rod with a swab coated on goo gone or gun solvent to clean the bore. then pass a couple of swabs to soak the residual goo gone. then run a swab with 1 DROP of gun oil. up and down twice. then pass clean, dry swabs until they come out clean and dry. your barrel will be clean. it should not diesel anymore which will give you quieter shooting. as for the twang, no real solution but fitting a gas ram. hope it helps.


PS. i hear that filling the stock with rags or foam muffles the twang. have not tried it on my shadow, but is not that loud anyway.

HI Jason,,,,

Do go ahead and clean your barrel, sounds like it needs it..... but DON'T use any gun solvent.  Matter of fact don't use a metal cleaning rod either.  

Get yourself a length of "weed whacker" line.  Sharpen one end to a point and take a lighter and heat the other end to form a small round "bulb" on the end then let that cool.  

Use the sharp end of the weed whacker line  and thread a clean patch soaked with "Goo Gone" .  Insert the weed whacker line from the breach end and push it till it comes out the barrel, then grab it and pull the patch through the barrel.

Use this technique and keep alternating with the Goo-Gone and the clean patches until the patches come out clean.  ONce clean you won't have to worry about cleaning again until accuracy starts to diminish.  

Never a good idea to use regular gun solvent in an air rifle, it'll ruin your rifle for sure.....   Goo-Gone is all you need to clean the barrel.  
I wouldn't advise running an oiled patch down the barrel either.

your big cat comes coated with a polymer based oil from the factory to save the bore from rust while is being shipped (generally by plane, in their little carbord box wich can't keep condensation out) then placed on a shelve til we happily adopt them. that coating is thicker than oil so it takes sometimes up to 50+ shots to burn it off. when it burns, it does not necessarily walk out of the barrel, but it sticks to the rifling in the barrel, disrupting the original grooves and slowing down the pellet. The solvent i use is used once to remove this coating only. it is not to be used for general maintenance. that is why i told you to make sure that it is completely removed by running swabs until they go in clean and come out clean. I have had a shadow for 5 years now and the barrel is in perfect condition. it is a bit tired now but originally it spat out 7.9 g at 910+ fps. cleaning the bore brought that number up to 940+ for 4 years. it now needs a spring but it is shooting fine and accurately so until it becomes unshootable, i'll keep it in then i'll ram it.

i'll retract the solvent, but do use goo gone. I did with wonderful results.

were would i get the goo gone?

You can usually pick it up at any good hardware store.  Also, I've seen it in the large pharmacy chain stores like  "Rite Aide", "Genovese" etc.  Look for it in the "Cleaning Supplies" isle.  It's a citrus based cleaner that is advertised for removing sticky gummed labels and such things.

one and last thing u want to do is open the back of the rifle ,the butt section and there should be two screws holding not sure cause i dont have that model but it s helpful in any gamo ,once its open stuff it with form not the expending one regular form put it tightly so u wont here so much twang that should help preety much beside gettin a turbo tune from cdt or gene ,this should help ....good luck and let us know how things went in case u need more assistance .....jorge...

You could fill the hollow stock with memory foam like I did, that will help quite a bit.

You could also do a home tune on it if you have the skills and tools but you will need a spring compressor to remove the spring.  Don't even think about removing the spring without a spring compressor.  You can find info in the "Library" section of GTA on some simple spring compressor plans.   Do some searches here and other sites and you'll find some helpful info on doing a home tune.  I'm sure the other members will help out.  

Of course there is also the option of sending the rifle to a pro tuner also.

Taking the rifle apart and doing a basic home tune is not all that difficult but it can be a little nerve wracking  the first time.  Of course it does require you to be confident in your abilities to take on the task.....

ok one last thing where can i get "form" and is it expensive can i put to much? or am i safe
: Re: gamo twang
: gamoluver1 May 05, 2009, 02:06:47 AM
if i were to put tar on the spring would i need a compresser?
: Re: gamo twang
: longislandhunter May 05, 2009, 02:43:48 AM
Yes because you need to remove the spring......

AS for the memory foam,,, I picked mine up in one of those home craft stores.  They sell curtains, pillows stuff like that,,,, they also sell the material to make your own pillows,,,,,,, including the memory foam.  AS for putting in to much, don't worry about that..... just filled the hollow stock until it's packed in full and you'll be fine.

Any furniture, auto, or marine upholstery shop will have ALOT of small scraps of various types of foam. Many foam distributors are no longer taking back the shops scraps to shread  and recycle, so you can probaly get them for free.

awww man so there gos my chance of tar on the spring =( ok well ill try the memoryfoam ppl say if you stuff the stock with diapers towels etc that helps also is that true?

".......... diaper towels..".



Not the used ones. they've already done enough "absorbing". ! :D

Question, why is it that one shouldn't  use gun barrel cleaning solvent  in a pellet gun barrel,....

..... but it's ok to use an citris based (acidic) cleaner in a steel barrel ?

Paul.
: RE: gamo twang
: gamoluver1 May 05, 2009, 04:12:41 AM
ok it's not just a steel barrel its because solvent is flammable wich means put that in a springer barrel = boom it will blow your seals and say good bye to your gun. citric is acid based not solvent

Foam comes in blocks and rectanges of various size and thickness, none of which are used in those sizes in the end product.

Since home, auto and boat seating is not block or rectangular,there is ALOT of cutting to shape whatever foam is being used. Dealing with all those scraps winds up being a major head ache and can fill trash cans rather quickly by the end of a weeks work. Any scraps too small to be used as part of a car seat, chair, or boat cushions get tossed.

Many foam distributors used to pick up the scraps during regular deliveries, grind them into small chunks to be used as chopped cushion filler, and give them back to the shops as part of their service. With the cost of doing business going up, suppliers want to sell more new foam so many have dropped that free recycling service.

Blow up the barrel ? Really?

Any gun solvent I've ever used, the instructions say to repeatedly patch the barrels dry until the patches come out clean - no fouling or solvent appearing on the patches. Then oil and dry patch after that until no oil on the patches.

Following the bore cleaner manufacturer's advice, I can't imagine there would be enough of anything left in the barrel to do any harm ?  

Not to argue, but I'm curious to know why that procedure would be a problem with a springer. And since that's exactly how I clean mine why it hasn't blown up ............. yet ????    :0

hmm well good for you i just know from expirience that ive had fire come out of my barrel

: RedFeather May 05, 2009, 05:11:21 AM
First, solvents like Gun Scrubber, Hoppes No. 9, etc, can diesel like they said.  They also can have harmful effects on the breech and piston seals which may not be made to stand up to them.  Second, your gun will still be a bit loud, even after you tar the spring (and you use very, very little tar - not gobs).  This is just what you get with springers, particularly the magnum class.  That piston is slamming to a stop with tremendous force and the spring is making some noise of its own, too.  Best bet is to stuff the stock with foam, as recommended.  

Do get that barrel cleaned.  Any dieseling is hard on the gun's internals.

goto Walmart, buy a $12 memory foam pillow, cut about 1/3 of it off, shape it to the stock and pack it in there. Use the other 2/3 of the pillow to, well, sleep on.

You will have yourself a memory foam stuffed butt ; )


Or, use a bedsheet  :emoticon:
