Loading Marushin 9mm MP40 / UZI Cartridges

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

What is the length of the wider end if the tool ? (step 6).
I have a Marushin S&W M39 and some cartridges.
I tried to load some carts but they won't fire.
Maybe it is because I don't have the right tool ?
The M39 was sold without the loading tool.

Yes they are good
I'm gonna check that as soon as possible.
Thanks Cerwyn !

i also put silicone grease on the screw thread as it helps to seal the round but also to stop the base sticking to the thread which tends to happen after a few shots.

Thanks for the tip Claymore
