Pellet doping

[maurice]

Maurice.
Lets talk airguns.I recently googled napier pro hunter pellets.They lube there pellets. The lube they use increases speed due to the fact that it is gassing off.

I call this pellet doping.I've experimented with this for 2years.Amazing results without any problems.

Soory if you play with this and have no PAL and you get caught by the law YU ARE IN DEEP CRAP.

Anyone else play with this concept.

Do you have any idea what lube they use? This idea intrigues me a lot.

Here is a statement from Napier's of London. they do warn UK'rs to be diligent and chronograph their rifle when using this product as it may put them over the UK limit.

The New UPH Hunter .22
simply the best performing airgun pellet of its type, it is designed to give consistent results in all std powered air rifles, both PCP and Springers. Every tin is pre treated with exactly the correct dose of Napier Power Pellet Lube, and they can be used straight from the tin. No need to sort or grade them, we have already done that for you. Expect improved accuracy, and consistency, it is likely that an increase in muzzle velocity will also be achieved. We recommend that UK airguns are chronographed occasionally to comply with UK power legislation.
Available in .22 cal 5.5 with a nominal weight of 14.5 Grains

Power Pellet Lube 10ml
A quite remarkable simple to use product that will improve accuracy with any pellet and on any type of airgun guaranteed.The unique complex formula does much more than lubricate, in fact it creates a chemical seal around the skirt of every pellet, ensuring that it will not skim or tear on the rifling of the barrel.
This is turn greatly improves the gyroscopic effect and results in improved flight, with dramatic improvement in accuracy.

And it seems they have a business relationship with AirArms

Napier is proud to be chosen by Air Arms for cleaners and lubricants used in manufacture and are the only product to carry their endorsement and recommendation. Now every new Air Arms gun supplied worldwide comes with an introductory sample of our oil


But so far I have not seen any claims about polymerization gases. Please post any info you have.

[maurice]

Merlyn you can purchase napier pellet lube. Read up on it on the web.Be care full how you use it.

I am new to the web and this is the first site i have ever posted info on.

I will not post factuall data about this topic until i am sure it is ok to do so

I'm not following this idea of "gassing off"?

People seem to have found that on some (not all it seems) airguns, pellet lube can help seal the pellet in the bore a bit better- i.e. less gas blow-by around the pellet. Is this what the term 'gassing off' is implying?

[maurice]

Eric no to the qestion.
Gassing off is the production of 2 seperate gases from certain oils, one being creanolein gas the other proethelein.Both are byproducts of the process of polymerization in the process of plastic production.
The heat genarated buy spring or gas ram airguns precipitates this process.

Gotcha....my apologies

[SeanMP]

I have a fairly decent understanding of the polymerization process as my Dad was a polymer engineer for his entire carreer.

What I'm having trouble with is I don"t know of any polymer prosseses that would yeild an exothermic reaction in a thousandths of a second. In fact the processes your describing which requires heat (endothermic) to initiate the catalyst phase produce condensate and heat during the chain phase(exothermic) and thats a relatively slow process as compared to oxidation reactions.

I'm not discounting what your seeing in your tests but from my (limited) knowledge it would seem that an oxidization reaction is more plausible

[SeanMP]

I think the OP might be refering to combustion as "gassing off"

I did follow a thread a couple years ago on another forum where a guy was treating pellets with all sorts of combustible lubricants and cleaners to find out what would happen. The upshot of all his tests is that the combustion of the products did increase the velocity however it was never consistent. The velocity bounced around like a yo yo even from something as small as dipping the skirt in WD40 and shaking off all the excess.

He concluded it was a waste of time.

At this time and experimentation only 20 fps max variation.method of application is crucial.
