Quick Answer
For 7mm Rem Mag rifles, a cleaning kit should include a solvent like Hoppes No. 9, a brush for the bore (e.g., a 7mm Remington Magnum chamber brush) and a rod. Use a dedicated rifle cleaning solvent for the magazine and action. Additionally, a bore snake can be useful for quick cleanings.
Cleaning the Bore
When cleaning the bore of a 7mm Rem Mag rifle, use a solvent like Hoppes No. 9, which is specifically designed to break down and remove lead and copper fouling. Apply a small amount of solvent to the bore and let it sit for a few minutes to allow it to penetrate and loosen debris. Use a 7mm Remington Magnum chamber brush to scrub the bore, working in sections and using a gentle back-and-forth motion to avoid scratching the rifling.
Cleaning the Action and Magazine
Use a dedicated rifle cleaning solvent, such as Break-Free CLP or Mil-Comm CLP, to clean the action and magazine of a 7mm Rem Mag rifle. Apply a small amount of solvent to a cloth and wipe down all metal surfaces, paying particular attention to the magazine and bolt face. Use a soft-bristled brush to clean the bolt face and other crevices.
Using a Bore Snake
A bore snake can be a useful tool for quick cleanings of a 7mm Rem Mag rifle. To use a bore snake, feed the snake into the barrel and pull it back out, rotating the snake as you pull to help loosen debris. Repeat the process several times until the snake appears clean, then wipe it down with a cloth and store it for future use.
