Yes. I load them. Handy to keep certain loads visually separate and easy to identify. I also like them for loads that may be stored extra long, since they don't tarnish. They were originally invented so that police loads in leather cartridge belts would not corrode and turn green. Some don't like them. Nickel plate is a bit harder than pure brass. Tiny bits of nickel can flake off, stick in the die, and start to scratch cases. If that happens, I polish the inside of the dies with 0000 steel wool and the "problem" goes away. The only other issue is they are a little bit harder on case trimmer cutters. If you have a carbide cutter, no problem. otherwise your case trimmer may need the cutter sharpened a bit more often.
