Ballistol Multi-Purpose Oil All-in-One

Ballistol is one of those amazing and successful companies that feature only one product. The multi-purpose oil comes in several different packages, but it is the same product. Ballistol has been in business since 1904.

Ballistol works on every part of the gun, from the barrel to the stock. The product can be used on nearly any metal surface and also works on material such as leather.

Ballistol is unlike other protectants that are basically PH neutral. Ballistol has a PH between 8 and 8.5, making the product highly effective for eliminating mild acids and human sweat. Ballistol contains a combination of anti-oxidants and high-grade oils.

Other lubricants on the market harden over time, oil begins to thicken and becomes sticky. Ballistol’s chemical makeup makes it less susceptible to hardening.  Rather than purchasing a variety of oils, lubricants, sealers, and cleaners, Ballistol performs each function well.

Ballistol can be used with a full concentration on most surfaces. However, as an example, if you wish to polish brass and silver, mix with water.

Why Practice Regular Maintenance?

  • Understanding your weapon better: taking a gun apart to maintain and lubricate helps you to understand how each part works in unison.
  • Reliability and Safety: consistent lubrication and maintenance remove grit and powder build-up for better performance. Residual fouling builds up in the barrel and receiver, creating dangerous shooting conditions.
  • Longevity: quality firearms can last a few years or a lifetime. Proper lubrication and regular maintenance add decades to the usefulness of a firearm.
  • Avoiding significant issues:  a dirty gun impacts everything from bullet drop and velocity to operation as a whole. Rather than waiting for failure, regular cleaning keeps your firearm functioning properly.

Gun Lubrication and Balance

Entire volumes are written on the effects and proper technique of gun lubrication and the correct amount of lubricant to use.  Every shooting enthusiast has an opinion on the right gun lubrication products, how-to, and plenty of tips.

What counts is what works best on your firearm and shooting application.

Lubricants provide some essential benefits to the performance and longevity of your gun. The primary rewards of using suitable lubricants are friction and metal preservation.

  • Identify the friction points on the gun. This identification is quickly made by looking for wear marks on the barrel, receiver, slide, and frame. Other areas of the firearm may need lubrication for friction reduction,  improving the ease of movement when the gun cycles through firing.

The controversy comes into play when the “amount of lubrication” applied to affected areas is questioned. Proper lubrication of a gun requires this basic tenet:

“If the shooter can see and feel the difference between dry metal and a lubricated metal friction surface, They have met the goal.”

Applying Lubricant to Your Gun

The first thing to remember, a little goes a long way. After the lubricant has been applied, if it moves by the force of gravity, you put too much on. Keep wiping away excess until the lubricant adheres to the surface without going anywhere.

If you choose to use high-quality gun grease, the same principles apply. Too much lubricant can be detrimental to the gun. Another point to remember; oil and grease degrade over time, so periodic applications are a good idea.

Final Thoughts

Every firearm enthusiast enjoys cleaning their gun and keeping it in top working condition. Lubrication is a critical product that can mean a few years for your firearm or a lifetime of reliable use.

The products above highlight some of the best new technologies, coming from a few of the best companies in the industry. Choosing a good oil lubricant or grease takes a lot of reading and actual tryouts of the product.

Whatever product or brand you choose, stick with it through the life of your gun.
