I really only use three of the same.
I entered five on the survey, but I forgot a couple.
Three Dillons; these get the most use. I have a small pile of charge bars which I use for specific loads. (I find trying to re-set a charge bar for exactly 7.2 grains of 'Something' powder a pain in the yarmush.)
One Frankfort Arsenal measure which I use - occasionally - for precision rifle loading. In fact, the Dillon measures do an excellent job of measuring out uniform doses in most cases. It has a 'micrometer' dial which is frustratingly misleading trying to find 'that exact setting' that worked so well three months ago.
One rather old Pacific Pistol measure. Back in the pre-Dillon days, the bushings provided an excellent system for repeating charges later in the month or year. However, the Dillon system works a bit better over all and so I haven't used this old dear for many winters.
A Lee 'Perfect' measure. It sounded so great; sort of like the Pacific Pistol measure, but for rifles as well. Of all the Lee reloading products - and I use many - this is the only one that really disappointed me. At first it leaked ball powder, then it leaked everything and it jammed all the time. I don't use it at all.
There's also a loading charge bar on the shotgun loader. It is integral with the loading machine so I don't think of it as a measure; it is, of course, but not in the conventional sense of being used for other applications.
