When you buy a Hoppes .22-.270 500 Cleaning Patch 500 Pack, you won't have to worry about stocking your cleaning patches for a while- depending on how often you use your gun. Part of being a responsible gun owner is doing regular maintenance on your firearm. After many uses, sediment and moisture cause the barrel to rust. Not only does this affect accuracy, but a rusted barrel will cause the gun to malfunction. Hoppes .22-.7270 500 pack cleaning patches are pre-cut for the appropriate caliber and gauge and uniformly woven for consistent maximum efficiency. All you have to do is attach the patches to the adapter of a bore cleaning rod and swab the inside of the barrel to remove sediment, and later oil. Hoppes cleaning patches are also ultra-absorbent.
