But I always liked using them even if they are slow. You have such perfect feel and control of seating depth.
I feel the same way about the Lyman 310 tool's "priming chamber". I have one for the '06 size case head, with which you can prime any case of similar diameter, one for .45/70 size cases, and one for the .45 Colt size which works with any round derived from the .45 Colt. I can even prime 7.62X54R cases with the .45/70 chamber.
