This is all over the Internet, so I'm not going to post any videos. But if you go to Youtube and punch in, "dieseling a air rifle" you'll get enough on the subject to keep you busy.
Apparently this got started in the UK and France, where air rifles are a lot more popular, because of strict laws governing firearm ownership. What it basically involves is taking a pellet and applying a dab of pure petroleum jelly, (Vaseline), into the hollow base of the pellet itself.
Then inserting it into the barrel and firing it normally. The high compressed air temperature entering the barrel "ignites" the Vaseline giving the pellet more velocity and energy. (Much the same way a Diesel engine operates).
The increase in velocity and energy can be substantial. Some guys are experimenting with other over the shelf combustables like WD-40 and such. This obviously won't work with CO2 powered guns because CO2 is not an accelerant.
I haven't come up with anything that shows seal damage, or anything like that. So I'm going to investigate this a bit more, and "give it a shot" in a couple of my air guns. It does produce a louder crack, similar to a .22, so I'll wait until my next trip to the range.
