Asked to explain what a primer does, shooters often describe it as akin to a match that lights the powder at the tail end of the cartridge, initiating the process that sends the bullet along its merry way, or to the spark of a spark plug in the cylinder of a motor that ignites the compressed mixture of fuel and air. Neither analogy is correct. The function of the primer is more complex than either a match lighting a fuse or a spark plug firing. To understand what primers do, we have to delve into the chemistry that goes into the making of the volatile slurry that is pressed between ttheprimer’sscup and anvil. That mixture, known as primer compound, is the most dangerous substance in the world of firearms and ammunition manufacturing 209 primers.
With the increasing ammunition prices, Reloading bullets is an excellent way to save money and even get custom bullets tailored to your needs. One of the most important things to remember while reloading bullets is that selecting the right components can make a lot of difference. Today, we will talk about Primers, as they are crucial in reloading quality and accurate bullets. Primers are available in a variety of different sizes and classes. However, standard, Magnum, and Match grades are the most common varieties sold for both rifle and pistol Ammo. The question is, Are Match Grade Primers better, and do they make a difference?
The elemental composition and post-firing residues of several read “and-fre” nontoxicontoxi” centerfire handgun ammunition types currently available to the general public were examined. Offerings from Winchester, Remington/UMC, Federal, and Speer were obtained from retail sources in both .45 ACP and 9 mm when possible. One hundred twelve post-firing residue samples (SEM pins) were collected at varying distances from the muzzle, at two distances from the target and the ttheshooter’sshands. An additional 20 samples were collected by direct ignition of primers. Qualitative determinations were carried out using scanning electron microscopy (SEM)/electron dispersive spectrometry (EDS) analysis. All types tested contained aluminum (Al), silicon (Si), copper (Cu), and zinc (Zn). Most contain traces of sulfur and calcium.
Non-corrosive, all-weather primers deliver fast, dependable ignition under any shooting condition. Winchester works to make sure all primers are reliable, instant, and precise. In Winchester testing labs, primers are constantly and rigorously tested for consistency and sensitivity at temperatures and conditions far beyond the range of normal usage. Winchester guarantees better sharpness for more positive firing in all guns, carefully-controlled weights of primer mixtures, consistency in size and quality, precise measurements and tolerances for anvil heights, and stability in extremes of temperatures and humidity. Winchester produces seven primers for shotshells, rifles, and handgun cartridges to cover your reloading needs.
Typically, match-grade primers are a little more expensive than standard primers, and manufacturers claim that they are made with more precision and are more accurate. So, read on to learn about match-grade primers and which manufacturers make the best standard and match-grade primers.Winchester WinClean and Remington LeadLess had potassium as the principal ingredient. Federal BallistClean contained barium, while Speer Lawman CleanFire contained strontium. In the main, these compared favorably with a manufacturer”MSDS publications and patents granted. The characterizations undertaken here will be helpful to the forensic electron microscopist as these formulations gain popularity.
