| I'm just starting to learn how to reload and I have a new Lee perfect powder measurer. Does anyone make a powder measurer where I don't have to covert volume to weight? |

Any of the ones with a built in scale would work. But in reality with the different powders out there why not convert? Its easier in the long run. I have attached an Excel spreadsheet I made for the Lee auto disk, it shows the volume to weight conversions. Always weigh the charge and verify before loading up your first rounds.

You set your PM, powder measure, throw a charge and weigh it on a scale. Then you adjust your PM up or down until it is throwing the charge you want. All done in grains. Lee is the only place you will see the volume stuff. The rest of the world weighs powder in grains. Look up some on line powder data if you only have a Lee loading manual.

I'm a newbie also, with the same unit. Do not go by what the micrometer thing says. You can use it to get kinda close, but its mostly going to be trial and error. Also, run a couple hoppers through it the first time you use it. There is some break in period. Run a couple strokes through it after each adjustment before weighing your adjusted dump. |

I gave up on trying to read the micrometer adjustment and just go by trial and error weighing each charge till I have it where it's consistent. I do have to say that once it's set it does seem to be very consistent in throwing charges. |

The marks on a PM (powder measure) are for reference only. Adjust charge. Write down number on the PM in your notes. Next time you want to throw that charge, look at your notes and set PM to that number. It will be very close. So you save time finding the correct adjustment of the PM the next time. |

It is a very accurate PM for the cost and is easily converted to be used on a press. you should have a scale.
Do the conversion to volume then adjust the PM check your charge against the weight thrown. Adjust till the weight is what you would like then record the volume # shown and note it in your records. I do highly recommend the micrometer and double disk kit they work great. |

| Forget about volume completely, that's for black powder. I use a Lee perfect powder measure and it's all I have ever used. Just get yourself an electronic scale to weigh your powder charge. The numbers on the drum are almost meaningless, you need to weigh it and take an average of at least three throws before settling on your charge after you adjust or make a change of adjustment. I like to set it to whatever charge I want using the electronic scale then load my rounds and always check the last throw again by weight. I'm happy with that. |

The only use I get out of the volume scale on the PPM is to get a starting point for drops to be weighed in a new load session. I've started just recording the volume piston length with calipers, though, for subsequent setup starting points for a given powder charge. It is easier than reading the piston & nut micrometer markings and I always use a scale to make sure I am using the intended weight.
