I have a list of charges ( capacity ) for a whole long list of metal cartridge casings, in the back of my Hodgdon Data Manual No.23. I think you can also find a similar list in the back of any Dixie Gun Works Catalogue.
The problems with all these numbers is that different manufacturers make these casings slightly differently, leaving more or less metal on the inside of the "web". We are only talking a couple of grains, MAX for smokeless powders, but it can make a difference with black powder--- not enough to blow up a gun----but enough so that someone else's " Favorite " load just doesn't shoot as well out of your dipper, and gun. Very old brass casings, like those made for the .45-70, and .45 Colt, have what is called " Balloon Head " casings. They hold several grains more of powder than do the modern casings for the same cartridges. The old Balloon head .45-70 casing could hold 70 grains of FFg powder. The newer casings hold about 65 grains of FFg powder- some more and some less.
If you are trying to avoid getting an adjustable powder measure for Black Powder, or a powder scale to weigh powder, you are being penny wise and pound foolish. I think every BP shooter needs a powder scale to weight the charges to check to see how close their volume measures are to what data you find written here, or elsewhere, which is given in "grains ", or " drams".
If scales cost a fortune, this would be alarming news. However, you can buy a good balance beam scale from RCBS, or Lyman, and several other companies for under $40.00. Check the big on-line suppliers, like Midway, or MidSouth to see about their prices. The last time I looked for this kind of thing, I found them for under $30.00, and that was in the last year.
I have an RCBS scale I bought 30 years ago, and it works just fine.( HINT: Look for used reloading equipment to get real bargains!) MY brother decided he just had to have one of those new electronic scales, and paid a lot of money for it. He gets a reading faster than I do with mine, but I don't personally think that " convenience " is worth the extra cost. If I was doing volume reloading of cartridge cases, I might be able to justify such a scale, as I like to check every 10th case of powder for weight to make sure the powder measure is throwing the same weight. Again, that is very important with smokeless powder loads. Its not with Black Powder.
One of my adjustable powder measures for BP has been set in the same setting for years. I decided to give it a good cleaning, to remove tarnish, and some vertigris that had formed. I loosened the set screw and saw a substantial difference between the oxides on the exposed shaft compared to that part that was inside the trunk of the measure. After cleaning the brass up with some copper cleanser, and then oiling everything, I put it back, and set the screw in the same place. Its gained a new patina in the last year just sitting in the bag.
Because handling Black Powder is going to get your hands dirty, that dirt is going to transfer to every brass think you have on the range, or in the field. Soap and Water will clean your hands, but most new shooters never think to take towels, water, and soap with them to the range. I have shared my gallon jug of water, soap, and paper towel roll with guys at my gun club for years at the end of a shoot- and sometimes during it!
Obviously, my " crud " level is not particularly low. I get around to cleaning brass stuff once a year or 5! :rotf: :surrender: :wink: I know men who spent way too much time in the military :hatsoff: polishing brass, and can't live with tarnished brass for a minute any more. Its in their blood! :shocked2: Just make sure you clean that powder measure along with everything else brass that you clean after a trip to the range, or field.
