FPS info?

[Wham-O]

I bought a gun collection from a gentleman a couple years ago and in the collection was a registered pellet rifle.
I asked the guy why I had to transfer the pellet rifle to my name and he said the muzzle velocity was more than 500 fps.
Now I've been kicking this thing around for a while (shanghi China Model 62) and to tell you the truth, if I shot a normal phone book from 15 feet it doesn't sink in 1/4 of the way.
Now....I think the power of this rifle is below 500 fts. Can I deactivate this from the system if I prove it's less that 500 fps?
How do I prove this?
If not...Is there something I can do to "strengthen the power" in it?
Much appreciated....

The registration of the firearm is based on two factors, actually. Many people focus on the velocity, but it has to be a combination of greater than 500FPS AND generating more than 4.2FPE (foot pounds of energy). BOTH have to be true in order for it to be classified as a firearm.

As for determining velocity, you can always get a Shooting Chrony (I have the base F1 model, about $125.00 or so). That will give you an exact readout of the muzzle velocity.
