Yes and different compatators will give slightly different readings on the same round

@Gibo Yep, hornady comparator. Sits on the blade of your calipers. You need micrometer style dies for them to work properly. I deliberately seat them long, measure them, work out how many thou deeper they need to go, then wind the die down that far. Works pretty well within a thou or so.

I don't have micrometre seating dies but have it pretty sussed how far to turn them. Im sure they would shave off some time though
