Beginner's Guide ... Loading Marushin 9mm Cartridges

Your modelgun will only function correctly if your cartridges are prepared and loaded correctly. This is intended as a Step by Step guide on how to do this.
Cleaning of used cartridges will be dealt with in a seperate article...

First of all, unscrew the cap from the cartridge and empty the case of it's components.


Tools required are



1. Loading tool 2. Cotton Bud (Q-Tip) 3. Small Brush.
Mascara brushes are ideal for this! Get your Girlfriend, Wife, Mother or just go yourself to the nearest Make Up shop and borrow sample brushes (Debenhams are ideal )

Silicone or Lithium based grease make perfect lubricants



The all important Cap, in this case Marushin 7mm



Check that all the parts are present... Cartridge case, Cap, Dished Washer, Cartridge Base...




Step 1. Run the mascara brush through the cartridge case and over the threads to ensure cleanliness



Step 2. Dip the Cotton Bud in either only a little Silicone Oil or WD40 and smear the inside of the catridge bore. This aids lubrication and gives a little extra smoke effect too.



Step 3. Place the Dished Washer into the cartridge, Flat face of Washer must face you like this...



Do NOT position the Washer like this...





Step 4. Squeeze a little grease from the tube, this much should be plenty, and smear it over the outside edges of the cap. DO NOT smear grease onto the powder charge in the cap.
Marushin cartridges rely on the cap acting as the blow back piston to operate your gun. The cap must be adequately greased to ensure smooth and free sliding inside the cartridge otherwise it will not function correctly.



Step 5. Place the cap into the cartridge, powder charge facing up



N.B. Faulty caps are sometimes found. If the "charge" falls away from the plastic cap like this, discard it as it will not ignite correctly.



Step 6. Push the cap down into the cartridge using the loading tool. Notice that the wider end of the tool is used, push the cap in only as far as the tool will allow




Step 9. Making sure the firing pin in the cartridge base is grease free, screw the base into place,



and there you go,



ready to move onto the next one
