DO NOT ADD ANY FLUID TO YOUR RIFLE SUPPRESSOR!!

You can get a substantial sound reduction by adding some fluid to a pistol-caliber suppressor. The energy from the burning gasses heats and vaporizes (boils) some of the liquid. This robs energy from the gas, reducing the energy available to make sound.

The reaction in a can from a low pressure / low volume pistol can makes a noticeable difference. However, the much higher gas pressures and gas volume generated by rifle cartridges has resulted in damaged suppressors. I can only imagine what the much greater gas volume of a .50 BMG would do if you try to shoot your can wet.

If in doubt, check with the suppressor manufacturer. But I would expect you to trash your .50 cal can in short order if you were to try shooting it wet.
