A while back, I bought one of those $30 Chinese pellet rifles. Its OK as long as you don't want to shoot tight groups. Anyway, I saw a fellow diesel firing his pellet rifle and it was pretty interesting. WARNING: Diesel firing a pellet rifle can ruin it or at least cause you to have to repair it. For $30, I figured, what do I have to lose, so I tried it today. Yep, it works. I shot at the side of my tin shed and then diesel fired at it and the second dent was a little bit deeper. It also makes more noise when you diesel fire it. Its not as loud as a 22 but it is a bit louder. If I had to use it for hunting or defense, I would definitely diesel fire it. For those who don't know how to diesel fire it, you just smear a tiny bit of Vicks Vapor Rub(or other fuel) into the cone of the pellet. The extreme pressure then heats the fuel until it ignites and gives the pellet some extra boost.
