When firearms enthusiasts shop for ammunition, choices often depend on the buyer’s shooting discipline. Whether a person hunts, shoots competitively, or just likes to visit the range from time to time, understanding what’s going into the firearm is a crucial part of getting the expected level of performance. In this guide, buyers will learn about the three most common types of RBS Ammunition rifle cartridges.
FMJ
Full metal jacket or FMJ rounds are widely used for target practice. They’re typically built with soft cores composed of lead, which is covered (or jacketed) in copper with a closed tip with the lead core exposed at the base. In military parlance, FMJs are often called “ball” ammunition. The jacket is substantially harder than the core, allowing the bullet to penetrate deep into the target rather than expand upon impact. While it’s not the best hunting round, FMJs are good for a lighter game and pelt preservation.
TMJ
A TMJ or total metal jacket round is similar to an FMJ in that it has a lead core covered in copper. The primary difference is that, at the base, each bullet’s lead core is covered in copper. Because the core is fully encased and protected from the byproducts of combustion, it reduces shooters’ exposure to lead particles. In many cases, it’s the only acceptable type of ammunition at indoor shooting ranges.
BTHP
A BTHP or boat-tail hollow point is often used during competitive shooting events. They’re also referred to as OTM or open-tip match rounds. Despite their hollow tips, which are much like pistol rounds used in home defense, performance is much different. A BTHP’s open tip won’t expand on impact like a pistol round; it enhances the bullet’s aerodynamic properties and ensures greater accuracy. The name refers to the bullet base’s tapered shape, which reduces drag. These qualities, among others, make BTHPs a popular choice for long-range shooters.
