adding 200+fps to any gun with no mods?

Reread my last post and that is exactly what I stated. But in all fairness if an airgun comes up that I have never heard of (most of them) it is a quick easy reference and a place to start ones research from. Like anything else though, dont' believe everything you read without doing a little of your own research. The Blue Book of Airguns 5th edition is a great jumping off place for further research, and does have some great pictures. And as, has been stated, just because the book says a certain pistol is worth so much, it doesn't mean squat when it comes to actually buying or selling an airgun.

^ If you meant me, I was just agreeing!

IMO it's a virtually worthless document except as a guide to what Dr. Beeman would like the prices to be, in his mind, based on what he has or likes. Or is promoting. Just my opinion, the market determines the price, the book is a guide with extreme prejudice.

Doing a bit of searching on the net, I was able to find three Barakuda's that have been put on the market within the last year. One was really beat up with a refinished stock for about 450, one for about 1300 and one for 1800. The one for 450 was on GunBroker and it sold, the the others may or may not still be listed, as it was a cached document from Google. The beater was a very old one, most likely from the late 50's going by its 5 digit serial number. Mine is 6 digit and was made in 1967 according to an email from Weihrauch.

As to the value of the Blue Book? I would only use it as a quick picture reference guide as there are numerous airguns that I do not have any information on. I find that the market will pay what it wants and I am sure that if I set my rifle up for sale in a show like Little Rock or Roanoke for 2500, it would sit there forever. Come to think of it, PT Barnam's saying might come true about one being born every minute. You never know.

Naw, I would probably only offer $2300.00. I think it is all agreed then. that it makes a good quick reference quide with some nice pictures and some information that should be taken with a big grain of salt until researched further.

For those that want to try to get their AG/S to diesel you may find this informative ...link..

Seems to me that this while the use of chamber lube with synthetic seals is not needed or recommended, the case cited in the link has little or nothing to do with the use of chamber lube. The seal pictured appears to be a factory original piston seal from an FWB 124. Those old seals have a known reputation for crumbling just like that, lube or no lube. Thermal degradation of a piston seal shouldn't be a problem in a gun thats functioning properly since any heat generated lasts only a couple milliseconds. Theres not enough actual heating of the seal to even say so. If the seal had been damaged by excessive detonation caused by combustibile oil in the chamber it would be burned and/or melted and cracked, not fallen to pieces like a crumbled cookie. That seal is just old and made of inferior material, with damage made worse from the owners continued use after the seal came apart. Nothing more or less.

Using a 'fuel' that ignites on compression might not be real good for the gun (seals) etc. There's going to be a pressure spike as well when the fuel ignites. Might want to plan on having some spare parts around in order to rebuild the gun

I think the main idea is much like what is pictured here:

This will bugger your barrel also they are not powder burners so the metal on the inside of an air gun barrel is softer & not made for a small explosion It's also very dirty.

Adding any combustible fuel will definitely detonate at the correct pressure but it will undoubtedly damage you air gun in a short period of time if continued, it really is not a good idea as it is extremely hard on the gun and the spring due to excessive pressure and the piston rebound. Many of the smaller or less powerfull airguns will not create enough chamber pressure to ignite the fuel but a high power airgun will. Have a look at many of the USA airgun web sites and you'll find with some searching that this is a taboo thing to add any fuel or combustible into the chamber of your gun or barrel. As for CO2 it will not support any combustion as the gas / fluid is inert. Need more power, best way is to get your FAC wich is not hard to do and buy a high power air gun, no chance of damage and power is always reliable and consistent. Normally an airgun fired with fuel in the chamber does increse velocity but the accuracy is 100% terrible as the amont of combustible is not metered exactly the same each time and the gun does not alway create the same chamber pressure every time. Accuracy is more important than power usually.

Hey, Razpizdiay

The same russian sites explain that the only advantage of such method is extra power.
Disadvantages are numerous and include:
- Unpredictable and non-repeatable pellet speed, which kills accuracy.
- Supersonic pellet speed kills accuracy.
- Internals of gun are eventually damaged. Mostly the piston seal, but even the mainspring may break in powerful springers.
- The bore is being polluted by the combustion products, which also kills accuracy.
- Diesel effect is unlike to appear in PCP/pump and especially in CO2 system.

If you still go ahead, then really no need in diesel fuel.
Virtually any flammable liquid does the job, including any lubricant oil.
And remember, the liquid vapors are dieseling, not the liquid itself.
