It's mostly been said, but I'll add just a little bit more, and this isn't "a basic"! I use pre-poured & pre-measured powder charges which I dispense from red tubes made by Rightnouer Manufacturing Company:
www.rmcsports.com . They're called EC loaders, and I use the little red ones with the orange tops (red tubes in photo on web site only have red tops for some reason, so don't get confused). These tubes are great, especially when loading a revolver's chambers. No funnel is required at the range, and you wind-up with more range time used for actually shooting and less spilled powder! For transport to & from the range, I use empty cigar boxes and the tubes lay well horizontally stacked.
I use my powder measure at home on the Kitchen table, with a paper towel on top of my plastic tablecloth to catch any spilled powder from being wasted as I pour the charges. I pour from the one pound can via the spout attachment with the rubber nozzle cap/stopper. It screws right onto the can. Pour from the can to the measure, tap a few times, top it off, then twist the funnel top of the measure and then put tube onto funnel and invert the combo. I do this for every charge I need for all of my black powder guns. You can develop a system of handling powder this way that will guarantee consistency and make it much easier to get accuracy with the Holy Black. When I'm done pouring charges, I carefully fold the paper towel in half, using the seam as a trough and then with the aid of a can funnel, pour the spilled powder back into the one pound can. Clean-up is a snap, with a soapy wet paper towel on the plastic tablecloth.
So like I said, a little more than basic......And a really good pistol loading stand isn't a bad idea either!
Have fun in this great hobby!
