Tex Jones, SASS 2263 Posted June 1, 2021 Share Posted June 1, 2021 From the Hodgdon web site: This data is by weight. Therefore, a powder scale is required. Do not use a dipper. If you are unfamiliar with this procedure get some assistance. Minimum Maximum Manufacturer Powder Bullet Diam. C.O.L Grs. Vel. (ft/s) Pressure Grs. Vel. (ft/s) Pressure IMR IMR Target 0.452" 1.600" 4.7 734 9,800 PSI 6.3 920 13,500 PSI Link to comment Share on other sites More sharing options...
Lucky Bastard Posted June 1, 2021 Author Share Posted June 1, 2021 Yes 5 grains is what I plan to go with. Thanks Link to comment Share on other sites More sharing options...
Bingo Montana Posted June 1, 2021 Share Posted June 1, 2021 The Lee powder dipper kit has a slide card to do the conversion from approximate grains of powder to Measure (dipper) number in cc. Looking at the slide card for IMR Target 4.2 grains is the 0.50 cc dipper and 5.9 grains is the 0.70 dipper. Link to comment Share on other sites More sharing options...
Cypress Sun Posted June 1, 2021 Share Posted June 1, 2021 Please keep in mind that grains are measured in weight, not volume. Link to comment Share on other sites More sharing options...

Sedalia Dave Posted June 1, 2021 Share Posted June 1, 2021 Yep and if you look at he chart you can usually find a combination of dippers to get you the load you want. With a little practice you can consistently dip exceptionally accurate charges with Lee dippers. As an alternative you can make custom dippers out of small cartridge cases. Solder a copper wire handle to the case and then trim the length till you get the desired charge. Or you can partially fill the case with JB weld and then fine tune the case volume with a drill bit or dremil tool to achieve the desired weight.

Sedalia Dave Posted June 1, 2021 Share Posted June 1, 2021 FYI the chart for the Lee auto-disk lists cc to grain conversions for the newer powders. Or you can use the Volume Measure Density (VMD) chart to calculate the volume of any charge weight. Link to comment Share on other sites More sharing options...

Alos a lot of us have Lee dippers that do not have newer powders on them GW Link to comment Share on other sites More sharing options...
Lucky Bastard Posted June 1, 2021 Author Share Posted June 1, 2021 I do have one small harbor freight one . But I'm using a single stage . And figure a vol. Measure would be easier and check on the scale every 10th round. Link to comment Share on other sites More sharing options...

But I'm using a single stage . And figure a vol. Measure would be easier and check on the scale every 10th round. I use one of these. Better accuracy than any electronic powder scale and costs a lot less. Smart Weigh Premium High Precision Digital Milligram Scale with Case, Tweezers, Calibration Weights and Three Weighing Pans, 50 x 0.001grams Accuracy is better than plus or minus 0.05 grains. The weighing pans are too small to be practical for powder so I just use the pan from my balance beam scale. One thing I learned early on is that these are sensitive to air currents and the air blowing into a room from a heat or AC vent can effect measurements. I have a window AC in my reloading shop and have to turn it off when using this scale. I also make sure it is sitting level by putting a small bullseye level on the pan before each use.

This is absolutely correct. Any decent scale will be effected by air currents. Link to comment Share on other sites More sharing options...
watab kid Posted June 2, 2021 Share Posted June 2, 2021 use good common sense - i watched a guy destroy a real fine revolver last weekend because he was not careful reloading , no one was hurt but it could have been bad , powders mearsue differently in the same dipper - i know nothing of that powder so its worth weighing the charge before you start going along , i agree with phantom on this weigh it , be sure you know what you got before you load the revolver or rifle Link to comment Share on other sites More sharing options...
John Boy Posted June 2, 2021 Share Posted June 2, 2021 This digital scale is not effected by air currents because it has a strong quality strain gauge compared to others on the market. Been using the same one going on about 5 to 8 years ... cheap, Accurate and free mailing ... I even bought a back up if the scale should be discontinued https://www.dx.com/p/kl-50-high-precision-50g-0-001g-mini-electronic-jewelry-scales-0-005ct-2057042.html#.YLb2XC_3ahB Also buy a universal powder funnel pan and your good to go https://www.opticsplanet.com/lyman-powder-pal-trade-universal-funnel-pan-7752433.html Strain gauge ... https://en.wikipedia.org/wiki/Strain_gauge Link to comment Share on other sites More sharing options...
