The question of whether or not “Do Polymer Coated Bullets Create Smoke On Firing” is a common one among shooting enthusiasts. The answer, as with many things in the world of ballistics, is nuanced and depends on several factors. Let’s delve into the details to understand the combustion process and how polymer coatings play a role.
Understanding Smoke Generation with Polymer Coated Bullets
The smoke observed when firing a firearm is primarily a product of the burning propellant. Traditional lead bullets, often jacketed with copper, don’t contribute significantly to smoke themselves. However, the switch to polymer-coated bullets introduces a new element to the equation. The key to understanding whether polymer coatings create smoke lies in how the coating interacts with the extreme heat and pressure generated during firing.
The polymer coatings on bullets are designed to reduce friction within the barrel, leading to improved accuracy and reduced lead fouling. But when the bullet is fired, the intense heat can cause the polymer to vaporize or combust partially. This incomplete combustion can result in visible smoke. The amount of smoke produced depends on:
- The type of polymer used in the coating.
- The thickness of the coating.
- The specific propellant being used.
- The firearm’s barrel length and condition.
It’s important to note that not all polymer-coated bullets produce excessive smoke. Many manufacturers have formulated their coatings to minimize smoke generation. Some shooters also experience what they perceive to be “smoke” which might actually be vaporized lubricant or residue from cleaning solvents in the barrel. However, compared to traditional jacketed bullets, some polymer coatings can indeed contribute to a slightly smokier firing experience. Some popular polymer coatings are:
- Hi-Tek Supercoat
- ACME Bullet Company’s coating
- SNS Casting’s coating
For a deeper understanding of specific polymer coatings and their effects on smoke generation, consult the manufacturer’s data sheets and reviews from experienced shooters. These sources often provide valuable insights into the performance characteristics of different bullet types.
