The .22 bore gets dirty faster than any other caliber - and a brass slotted tip is the quickest way to get solvent into it. This .22 caliber brass slotted tip threads onto a standard cleaning rod and holds a cleaning patch in its slot for push-pull bore cleaning. Fold the patch through the slot, push it into the bore, and work it back and forth to coat the rifling with solvent. Solid brass won't scratch the barrel, unlike the plastic tips that come in budget cleaning kits and snap after a few uses.
No caliber gets more rounds through it per range trip than .22 - and that volume means fouling stacks up fast between cleanings. The first step in any bore cleaning session is getting solvent into contact with that buildup, and a slotted tip does this faster than a jag because you can scrub the same patch back and forth without it falling off. One wet patch, ten back-and-forth passes, and the solvent has reached every inch of rifling. A jag would need ten separate one-way passes with ten separate patches to cover the same ground.
Experienced shooters keep a slotted patch holder and a jag in their gun cleaning kit for different jobs. The slotted tip handles solvent and oil application. The jag handles final dry passes where tight bore contact matters. It's one of the most overlooked gun cleaning accessories - but for bore cleaning on your .22, start with the slotted tip wet, finish with the jag dry, and the full routine takes minutes.
