can anyone tell me a bit about this, 1 where to buy, 2 how to do,ive read some interesting stuff on this on the yanky sites and appears to have a lot of positives,CHOP.

Hi Chopper , I use Moly Z powder made by Dow corning . I got a small bottle via Ebay .. but I know you can also get it from industrial suppliers like CBC bearings or Blackwoods ( if they are feeling motivated to help ) as well as places like http://www.sinclairintl.com ( online order / from the US )
I also tried a different approach to the actual coating of the bullets ( being bit of a tinkerer and wanting to get things done fast rather than the 3 - 4 hours for tumbling I had read about ) . I went to bunnings hardware , bought a $20 palm sized orbital sander . I clamp this up side down in a bench vice with rubber vice protectors to absorb some of the vibration and noise . I then get a rectangular plastic air tight kitchen container ( food container ) about 500 ml in size . Add 1 teaspoon of powder , about 100 30 cal projectiles that have been cleaned in hot soapy water then rinsed off with Metho or lighter fluid and allowed to dry . Cable tie the container to the base of the sander and turn on for 5 - 7 minutes . When complete , dump the contents into a sieve with a clean piece of paper underneath .. shake to separate the moly and return the extra powder to the container . Then put the coated projectiles in an old towel , roll up ( into a tube ) holding each end and shake back and forth to remove the extra moly and polish the projectiles . So far I have coated about 500 projectiles with the same 1 teaspoon of powder so it does last a long time . Andrew Smith

As a side thought , Moly powder is hydroscopic ( absorbs moisture ) . The bottle I got via ebay must have been opened / old stock as the powder was " clumpy " rather than a very fine - free flowing powder . To fix this I spread it out on some Aluminium foil in my oven on low for about 1 hour to drive out the moisture ( also dried out my moisture absorbing silica gel packs at the same time ) . The powder is now stored in an air tight container with a silica gel pack in it to keep it dry .

Chopper,

Pro-Cal has moly powder in small lots.

Another idea for tumbling is to bind a plastic container in a towel and put it in the clothes dryer!

Alan,
If i put anything like that in the clothes dryer, you would hear my beating in Maffra. Some how i do not think "she must be obeyed" would not understand.

Hi Peter
I built one with a 12v windscreen wiper motor and a 150mm dia piece of conduit, glued one end and put on a screw end onto a piece 150mm long and put in 3 pieces of 20x20mm timber to grab the projectiles, works very well and tumbles at the right speed.

Yes the clothes dryer would be risky. If something went wrong it could be "she who must be grovelled to for a considerable length of time"!
