    .0005" is best case, with the best calipers. If you have spectacularly shitty ones, your accuracy might be more like +/- .005", or ten thou.

    I use calipers for reloading; rifle cases need to be trimmed because brass flows under pressure, and you def. have a minimum and a maximum tolerance.

      Plus handling errors, of course.

      But yeah, a $170 Mitutoyo caliper will also not display anything beyond five tenths, so that’s definitely a hard limit.
