The Lyman Large Primer Pocket Uniformer (part number 7810215) cuts a large rifle primer pocket to a uniform, SAAMI-spec depth so every primer seats at the same depth for consistent ignition. Precision rifle reloaders run this steel-and-wood hand tool on large-primer-pocket rifle brass as a case-prep step before priming, since an inconsistent pocket depth is a real source of ignition and accuracy variance.
