I’ve been back and forth with ordering one as they are so load specific with their separate rotors. I loaded some 41 special with 220gr Montana cast over 7 gr of unique. Shot very accurate, but I had some sticky extraction with no other obvious signs of excessive pressure.ie. Flattened primers. Figure the gp-100’s cylinders are cut tight. Turns out the dandy has a rotor that will throw 6.6 gr of unique, that’s all I need for a excuse to order one! Results to follow .

Not to be a "Debbie Downer", but that rotor may or may not throw 6.6gr of Unique (you need to check actual charge on a scale - which you probably already know). I have a couple of the powder measures and all rotors (collected over many years). One of my most useful loading tools. If you don't have one, here's a link to a downloadable PDF Chart of rotor charges with various powders -- a lot of currently avail powders aren't shown on the chart. rcbs.com/RCBS/media/RCBSMedia/PDFs/Parts/LittleDandyChart.pdfPaul |

I hope this isn't considered a hijack but does anyone know how to convert this chart to a spreadsheet(Excel)? I don't really want to re-create the whole chart from scratch.
Sure would make it easy to make adjustments to charges based on actual checks. I've got a few actual weights for a couple of rotors. My usual procedure is to throw 10 charges and weigh for a total weight for the 10 and divide to get an average. Sometimes I will do it twice to make sure I didn't mess up.

That link paul105 put up is a quite complete spread sheet type pdf file. rcbs.com/RCBS/media/RCBSMedia/PDFs/Parts/LittleDandyChart.pdf I have it on my computer also. However it's not editable. |

Oh Well! I can always start my own spreadsheet just using the powders I have on hand.
One thing about that link for the chart. It doesn't produce a readable printout. At least I haven't found a way to make it print big enough to read. Even with a magnifying glass, it is difficult for me.

It is a jpeg. Simply hold the Ctrl button in the lower left corner down and hit the + button till you get it the size you want. It has scroll bars also to move it around.

The #13 rotor according to the chart should throw 6.6 gr of unique. In actuality it throws ,at least the one I have, 6.0! Not even close! I threw 20-30 charges and each were 6.0. I even emptied the hopper,refilled and tried again. Very consistent though. So I just bought #12-14-15-16 rotors Figure the next rotor up in volume throws a stated 7.2 grns and the others incrementally higher I’ll be able to come close to the just under 7 grns I’m looking for. We will see! |

I have one and have ended up finally accumulating all the rotors for it. Rotors don't always throw exactly the amounts listed on the chart. I've noticed the weights can be off and tenth or two different times of the year with the same powders. Probably due to changing humidity levels.
I like it and use mine a lot.

I've had mine for years. Accumulated all the rotors. Accurate enough. If more precision required, use the Redding.

Had the :Lil Dandy" since they were introduced, several of my rotors throw "light". They are handy and work well for building plinking loads. I need a #13 at the moment.

I like them for very small charges. Found the very small rotors on Amazon.
