Fully Encapsulated Base Ammo: FEB Bullets Explained

A fully encapsulated base bullet (FEB) has just what the name implies – a base (usually lead) that is completely surrounded by another harder metal, such as copper. This type of bullet typically has good accuracy and is primarily for indoor shooting ranges. Some manufacturers call this "clean range" ammo, as they use the FEB bullet and a mercury-free primer to create an environmentally friendly bullet.

Because the covered lead base prevents airborne lead particles from causing air safety concerns, FEB ammo has pretty much one use – indoor shooting. Most newer ranges have great ventilation, so it’s not much of an issue. But with lead, it’s always better to be safe than sorry. 

Fully Encapsulated Base Advantages

Obviously, the main advantage is lead safety. But another advantage to this bullet is the variety of calibers offered – with 9mm, .40 S&W and .38 Special among the most popular. There are FMJ and TMJ designs available, and every manufacturer will have various lines and styles that have that coated base. Most of these remain common as target shooting ammo, but you have plenty of options and this can let you try out all kinds of ammunition before you decide on going with a more traditional type. Some shooters simply prefer encapsulated base ammo for multi-purpose use.

Fully Encapsulated Base Disadvantages

The only real disadvantage to this type of ammo is that it has a specialized bullet. While perfect for indoor ranges and shooting on your property, it’s not a good choice for hunting or defense use, as it is not designed to expand when it hits a target like specialty self-defense ammo.

Overall, if you’re looking for good indoor range ammo, you can’t go wrong with fully encapsulated base as long as the range allows. Some prefer absolutely no lead or maybe even their own reloaded ammo instead. While this can seem limiting, safety is a priority at indoor ranges.
