Reload sounds aren't workin

I’m trying to make a Swep for ttt with a model of a other Swep called the M82.
I got the model, and fire sounds working, and the only thing I haven’t got yet is the reloading sounds.
Now, these reloading sounds, just seem to not work, but first, lemme tell you a little about them.

The Swep has 4 reloading sounds, boltup, clipout, clipin, boltdown.
None of em work.
Please help.
