RE: Black powder and black powder suds
Just have to add on the whole time thing -- it amused me at the public range when people gave me a hard time about how long it took to reload the ML between shots, claiming it took to long to shoot them. #1, if you wanted to shoot accurately in the summer you needed 3-5min between shots with any gun (though many of them thought any 100yd group minute-of-pieplate was GREAT), and once I started reloading I learned that it took more time to reload a quality rifle cartridge than to reload a quality ML shot.
The only difference was I had to reload the ML at the range, and I could reload the rifle shell at home during the winter when I had nothing better to do...
