I sure like my RCBS Little Dandy powder measure; it's a lot faster than throwing charges with my B&M powder measure. I have both an old and a new rotor charge table for it, but neither one lists 800-X powder. I use 800-X in both 45 ACP and 38-40, and like the results. I wonder why RCBS doesn't list 800-X?

I know that 800-X is difficult to measure, however; the big, light, sticky flakes often bridge in the B&M and I have to put that charge back in the hopper and try again. Perhaps RCBS has found the same thing with the Little Dandy; does anyone have any enlightenment?

All I can tell you about the Little Dandy is it is just that!

Second, don't trust the charge tables, new or old, they aren't accurate. They give an approximation, but due to manufacturing tolerances the listed charge will usually be light, as much as 1/2 grain. Just like Unique, 800-X will probably do best in the rotors with the larger diameter holes. Depending on when made the transition between the small hole, ca. 5/16", and the larger, 3/8", occurs between rotor number 12-14. I have a large 12, and a large and small 13!

If you have a scale, and I certainly hope you aren't attempting to reload without one(!), it is easy to create your own charge table. Start out with a rotor that throws 700-X in approximately the charge you want. Then, using 800-X throw and weigh several charges, the more the better, to determine if that rotor is consistent with 800-X. If it is, then throw 10 charges together in the pan and weigh it. Divide the total weight by 10 and you have the average charge that rotor throws. Simply record this information and you are started. Do the same with all your rotors and you have a chart.

If you need a charge that is between two rotors it is easy to adjust the lighter one by drilling the chamber deeper and checking frequently until it throws the charge you want. Be sure to mark modified rotors so you know they have been altered, and note the marking in your chart.

Be aware that a fixed measure like this will throw progressively lighter charges as the powder ages if not all used in a relatively short period of time. This is caused by the solvents evaporating, the mass of actual propellant in a given volume remains the same so don't keep adjusting to get the same charge weight as this happens.

There is also a member who makes an adjustable Little Dandy rotor, he will probably be along eventually.

You're probably right - and then, I think 800X is also rarely used in pistol loads, from what I see. In my neck of the woods, it is not easy to find off the shelf.

I got a couple cans of it at a bargain and I used it in .45 Colt loads for a while. Liked it a lot, but it is a bear to use in some powder measures. After that, I determined it was easier to go back to using powders that metered better in my Dillon.
