If you are referring to those brass thingamabobs that measure a priming charge then NO. I usually use a small priming horn or prime with what I'm shooting at the time.
I used to use the other type nut some shoters stated they were unsafe. I found that they did not hold enough priming powder for a full day at the range, they got clogged from soupy pans (high humidity makes the pan soupy or muddy) or I use my main horn.
