They are bonded together in a way that ensures they will not separate. The main body of the case is one section, while the shoulder/neck is another. The polymer section of the case is molded in two separate operations. Weight-obsessed backpack hunters and rifle competitors who have to carry gear over long distances also will appreciate the weight savings, however minute. Not to mention the savings of the shipping costs for the military, which has to move vast quanities of ammunition across the globe. For example, an individual soldier can carry three extra 30-round magazines of True Velocity 5.56mm at the same weight as traditional brass case ammo. This might not be a huge advantage for a trip to the range, but it is a game changer for military applications. A given load of True Velocity ammunition is roughly 30 to 40 percent lighter than comparable brass-cased ammo. There are other benefits of the mostly polymer case, one of them being weight. Anyone who has had to police brass after a major training event can appreciate how valuable this is. Using a magnet, cases can be picked up with minimal effort, which has the side benefit of reducing an individual’s exposure to toxic chemicals that are byproducts of fired ammunition. The case starts with a stainless steel head, which True Velocity calls the “insert.” Steel offers three important qualities here: It’s strong it can be machined to exacting tolerances and it is magnetic. True Velocity’s cases are manufactured using state-of-the-art equipment, most of which is automated. The case can be tightly controlled during manufacture and does not transfer heat like brass does. True Velocity’s ammo consists of a polymer case and a steel case-head insert. By molding rather than drawing the cases, True Velocity claims it can produce superior dimensional consistency, both inside and out, to any brass case on the market. With today’s bullets, primers and powder, brass is often the weak link in the chain.īy eliminating brass from this equation, True Velocity is able to build incredibly consistent ammo, and when it comes to reliably hitting the target, consistency is everything. Quality, strength and dimensional characteristics can vary wildly. The quality of the end product can vary based on the materials, processes and specifications used in production. In most cases, the brass is annealed after each step in the forming process. The traditional method of producing brass involves drawing batches of raw material through progressive dies, punches and trimmers until the case meets its proper dimensions. That’s where True Velocity’s technology comes into play. To accomplish this, we want the case to be as straight and consistent as possible, and we want the material to flex appropriately when fired. In order to do those things well-to produce accuracy downrange-is where the wheat is separated from the chaff. The case encapsulates the propellant, holds the primer, secures the bullet and obturates to seal the cartridge into the chamber as it is fired. Let’s begin by discussing what a cartridge case is. Polymer-case ammunition is here, and the results are impressive. The result is an innovative product that is already having a big impact on both the military and civilians. Brass has served us well for decades, but is it really the best material for the job?Ī company called True Velocity Ammunition decided to push back against the conventional wisdom that has permeated the ammunition world for years.
The material is so synonymous with cases that the term “brass” will be forever part of the shooter’s lexicon. Since the latter days of the Civil War, most of the world has used brass cartridge cases for centerfire and rimfire ammunition.
