Rest the gun in a vise with the action open and muzzle slightly down. Put an 8" piece of rubber surgical tube on the Wipeout nozzle and stick the other end into the breech. Hold it tight to the breech, it will seal somewhere in the forcing cone, and give about a healthy 1 second burst. Hold the tube until the Wipeout stops expanding out of the muzzle then remove the tube. This method keeps the stuff out of the action and cuts down on waste.
I use the same method.It works great and no mess.
