Why your cleaning rod matters more than your solvent

A bore is a precision-machined surface measured in ten-thousandths of an inch. The two things that wear it out fastest: incorrect cleaning, and corrosion from poor storage.

What kills a bore

• Multi-piece aluminium rods that flex and rub the muzzle crown — the single most accuracy-destroying part of a barrel.
• Stainless steel rods used without a bore guide.
• Reversing brushes inside the bore (always push out the muzzle, then back).
• Skipping a bore guide on a bolt-action — solvent washes into the trigger and chamber.

What to buy instead

• A single-piece coated rod (Dewey, Bore Tech, Tipton — the brand matters less than the construction).
• A correctly-sized bore guide for your action.
• Bronze (not steel) brushes one calibre size below the bore.
• A brass jag, not a slotted tip, for patches.

Total spend: under $150 for kit that lasts decades and treats the bore the way the bore deserves.
