What type of powder coating is used for bullets?

Use of a spray gun is called ESPC method = Electrostatic powder coat (applied with a spray gun using a static charge). You can always buy an Electrostatic PC gun to get the smoothest finish, but it comes with more setup, more cleanup time and some powder will be lost.

What is coating on bullets?

There are three common bullet coatings: Molybdenum Disulfide (Moly), Tungsten Disulfide (WS2 or Danzac), and Hexagonal Boron Nitride (HBN or “White Graphite”). All three products have very low coefficients of friction, and, when applied correctly, all three will do the job.

How fast can you shoot powder coated cast bullets?

In the . 308, consistent accuracy of 1.5 inches or so for ten shots is fairly easily attainable at velocities nearing and exceeding 2600 FPS with 165 gr. cast bullets.

Why do people powder coat lead bullets?

Coated bullets offer several advantages for handloaders. Coatings that cover the entire bullet, including the base, reduce or eliminate the exposure to lead during handloading and airborne lead particles when shooting. It also means you no longer have to scrape out built-up wax lube from your seating and crimping dies.

Are coated bullets any good?

Advantages of polymer coated bullets are less friction between the bullet and the bore, less smoke, less debris such as lead left in the barrel, no toxic off-gassing, contains no Moly-Disulfide to gum up your dies, works great in bullet feeders, great for indoor shooting where lead bullets are restricted, non abrasive …

Are coated bullets faster?

Generally, the coatings are good for velocities in the 1200-1500 fps range, similar to copper plated bullets, which covers the speeds of most handgun cartridges. My experience has been that they produce about the same velocity as cast bullets with the same powder charge, but may be a little slower.

How long does liquid ALOX take to dry?

Mix the bullets around until they are all coated. Lay the freshly coated bullets on some wax paper to dry. Liquid Alox will usually dry enough overnight to reload the next day, depending upon the humidity. If you subscribe to the “more is better” line of thought, your coated bullets may never dry.

Why do you lube cast bullets?

Cast bullets require lubrication to prevent leading. Bullet lube serves not only to lubricate the passage of the bullet down the bore but also to seal the propellant gases behind the base. One of the most important properties of this lubricant is that it must be able to flow to be most effective.

Why does powder coat Your Bullets?

Why powder coat? Lubed bullets are simply that, grease applied to the bullet alloy to reduce leading; Powder Coating (PC) is more than just another lube or coating providing lubrication. Since PC does not leave a lead residue it can be shot in polygonal barrels such as Glocks. PC is a superior bullet lubricant at preventing lead deposits.

What is ‘powder cutting’?

Frequently Asked Questions. Powder cutting is oxygen cutting in which a suitable powder is injected into the cutting oxygen stream to assist the cutting action (definition from BS499:Part 1:1991 Section 7 No.72 008). Oxygen cutting (also known as oxy-fuel cutting) is the thermal cutting of materials by chemical reaction with oxygen after…

What is powder coat system?

Powder coatings are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives. These ingredients are melt mixed, cooled, and ground into a uniform powder similar to baking flour.

What is a powder coat gun?

The powder coating gun serves the purpose of electrically charging the powder and propelling it towards the parts you are powder coating. The amount it charges the powder is measured in KV/kilovolts (1,000 volts = 1 kilovolt). Cheaper guns have a pre-selected KV and more expensive guns allow you to choose.
