Bullet Abbreviations

There are two major fundamental differences between reloading and remanufacturing:


Reloaders generally have a one-stop shop machine for their entire “process”. The de-priming, sizing, priming, powder dump and projectile placement/crimp are all done with the pull of a handle (or several pulls of a handle). Generally, the sizing die only sizes the top third or so of the case as it passes through the “sizing station”. While this process is somewhat effective, it completely misses some of the expansion that happens in the lower portion of the shell casing.

Remanufacturers have a much more stringent process for reconditioning the brass: we either roll the casing through a machine specifically designed to affect the entire casing, or we punch it completely through a resizing die. This way, every part of the casing is brought back to the original specs.

Each casing is pressure-checked prior to making it to the priming machine. The equipment verifies the integrity of the brass and rejects any casings at risk for failure.


Our machines in the remanufacturing process check EVERY round after the powder is dropped into it. In fact, this equipment is so sensitive, that it stops completely if something is amiss.

This is profoundly different than a reloading process (which is not what we do). In reloading, powder grains are only measured when the operator decides to pull out a round and dump it on a scale, which leaves a lot of room for error.

Everything we load is within specifications published by S.A.A.M.I. For more information on what their recommendations are, visit their website: www.saami.org


What’s with the alphabet soup?

There are TONS of different abbreviations for the projectiles used in cartridges. Here are a few that we use:

RN- Round Nosed bullet. A round nose bullet offers more reliable feeding in finicky semi-auto firearms that may not function well with other types of bullets.

FN- Flat Nose bullet. This is sometimes referred to as Flat Point as well, but we use the language "Flat Nose" for consistency. A flat nose projectile is ideal for cutting a clean hole through a paper target to help you see the point of impact from greater distances from the target.

FMJ- Full Metal Jacket- the projectile is essentially pushed into the “jacket”, leaving exposed lead on the back.

TMJ- Total Metal Jacket, meaning the lead projectile is totally encompassed in the plating.

P- Plated. For us, a shorter way of saying TMJ. P will often precede the letters indicating the shape of the projectile.  Ex: PRN= Plated Round Nose

BT- Boat tail. Refers to the shape of the back of the bullet. Boat tails are widely known for having less drag.

SP- Soft point. Provides more penetration before expansion when compared to a hollow point.

HP- Hollow point. Provides a lot of expansion on impact. Mostly use for hunting/defense.

THP- Target Hollow Point. This projectile flies like a hollow point, but doesn’t expand the same way a modern defensive hollow point will.

HB- Hollow Base. The Hollow Base on some of our rounds allows the bullet to be longer and provides more contact area with the barrel and rifling which will stabilize the bullet and improve accuracy.  The bullet profile is longer but the weight of the bullet remains the same.  The hollow base bullet is a favorite among target and competitive shooters.

TMK- Tipped Match King. This is a projectile with polymer tip, ideal for precision rifle rounds.

SMK- Sierra Match King. Sierra Bulletsmiths are the manufacturers of these incredibly precise projectiles. This is an open-tipped match king. The hollow point on these is designed for less drag on the projectile rather than a defensive-style hollow point.

What does subsonic mean?

A subsonic projectile is one that travels less than the speed of sound. The super-sonic "crack" that is typical of a cartridge being fired is minimized; however, to experience maximum benefit from subsonic ammunition, a suppressor is recommended.

Does using remanufactured ammunition void the warranty on my firearm?

No. We’ve called several firearm manufacturers to try to understand how this rumor started. A firearm’s warranty is against defects in the firearm. If the ammunition caused the problem, the firearm’s warranty won’t cover it- it doesn’t matter who made it. That being said, we take full responsibility for what we produce. We are fully insured and our ammunition is guaranteed against defects in our assembly process.



I received ammunition that is silver. Did you send me steel-cased or aluminum ammo?!?

No chance. We absolutely do not load anything in-house with steel or aluminum casings. We use only brass, but sometimes we're able to use nickel-plated brass. Nickel plating is silver and is more tarnish-resistant than brass, but don't worry, it's still brass.
