Lee Primer Pocket Cleaner Lee 90101 Primer Pocket Cleaner

The Lee 90101 Primer Pocket Cleaner is a double-ended reloading tool designed to maintain clean primer pockets across your spent brass. Whether you're prepping large or small primer pocket cartridges for a reload, this simple hand tool removes residue and debris that can interfere with primer seating. Clean primer pockets mean more consistent primer engagement, which translates to tighter groups and safer, more reliable ammunition. If you reload rifle or pistol rounds with any regularity, this is one of those small-cost accessories that pays for itself in precision and consistency.

The two-sided design eliminates the need to swap tools—just flip it over to match your primer pocket size. It's straightforward to use: insert the appropriate end into the pocket, give it a turn or two, and you're done. No complicated setup, no learning curve. It fits naturally into any reloading bench workflow, whether you're batch-processing brass or doing a case-by-case deep clean before the big hunt.

Lee Precision built their reputation on making reloading tools that work without the premium price tag of name brands that rely on mystique rather than performance. The Primer Pocket Cleaner follows that playbook: practical, reliable, and effective at its single job. For handloaders who understand that ammunition quality begins with case prep, this is a no-brainer addition to your toolkit.
