The Hoppe’s cleaning swab for .40 to .45 caliber is a soft cotton swab that threads onto a cleaning rod and wipes loose fouling and debris out of a large bore after shooting (Hoppe’s part no. 1324). It comes as a 10 pack, so a fresh swab is always ready for the next gun on the bench. Hoppe’s sells this swab in its rifle swab line and describes the cotton as soft enough that it will not scratch a smooth bore. The .40 to .45 sizing suits big-bore barrels where a small swab would slide through without touching the walls. It is a simple, inexpensive part of a cleaning routine that keeps fouling from building up between sessions.
