=== Shellholders ===
[[File:Shell holders.jpg|thumb|Different views of a standard type of shell holder.]]
A shell holder, generally sold separately, is needed to hold the case in place as it is forced into and out of the dies. The reason shellholders are sold separately is that many cartridges share the same base dimensions, and a single shell holder can service many different cases. While most modern single stage presses use a standard shell holder some older presses may need special holders.

Progressive presses, however, may use shell holders specific to the press manufacturer, and will generally only fit a certain make and model of reloading press.<ref name=nonte_2 />  A different type of shell holder is also required for use with some hand priming tools (e.g., Lee Autoprime tool)<ref>https://leeprecision.com/hand-priming-tool-shell-holder-set</ref> as well as trimming tools.
