DAL,
The short answer is not really. I do that all the time.
Now a precision benchrest shooter will no doubt take issue with that but, that is only because of the extreme precision and tolerances they are trying to maintain when loading their ammo with regard to headspace and the like.
For the average reloader, basically they are referred to as "Universal Shellholders" and that's the way I think of them.
Redding is currently making benchrest type shell holders with different top rim thicknesses for regulating shoulder position (headspace) in a given bottleneck cartridge. It creates the same affect as some reloaders do by grinding the die bottom down to shorten the shoulder to head length(headspace).
I'm Contender, and this has been today's moment in Reloading Die history.
