FMJs are made by a swaging process. The entire purpose of this copper is to keep lead from scraping off on the inside of the gun barrel. the bullet shape in your second pic in post #1 is called "truncated cone", or "round nose flat point" (looks more like tc than rnfp). These bullets are thought to be more useful when trying to wound someone or for target practice. In the above scenario, it can be broken down into non-defensive vs defensive. This is what is commonly-known as a full metal jacket. A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. The exposed lead creates more reliable expansion and is ideal for firearms that have feeding issues with hollow point bullets, considering the front of the bullet is easily fed … (This info is displayed on bullet boxes and product webpages.) As a side note, ballistic co-efficient does not = accuracy. Exposed lead creates more reliable expansion. Both from a functional point and from the safety stand point. FMJ, for “Full Metal Jacket” has a layer of copper over the lead core of a bullet. The vast majority of ammunition you see on the shelves at sporting goods stores is full metal jacket ammunition, also known as target or range ammo. The resemblance is there, but the two are not identical. I was looking into buying some .223 ammunition and the FMJBT is cheaper than FMJ, but both look like solid tip bullets....so are there any performance, etc. Standard bullets generally have flat or rounded tips that are made of a soft metal. Load data from any load manual or website can be used. Plated bullets are then copper plated via an industry-standard plating process. These types of bullets have a tendency to pierce through a target, leaving a clean entrance and exit wound. CMJs or "complete metal jackets" use a two part jacket. It is a good solution for some things, but I've seen many instances of tumbled CMJ bullets in open guns, most likely due to the partial separation of the jacket(s). Soft nose lead tipped bullets, more commonly known as soft points are projectiles with an exposed lead core that is partially encased in a harder copper jacket. The hollow point and the polymer tip will help to mitigate the danger of the round passing through the intended target and striking an unintended bystander. The copper plating is thinner and not as hard as an FMJ’s jacket. It also has an exterior metal shell, but the manufacturing process explains subtle differences. Full Metal Jacket ammo, or FMJ for short, is a bullet style that uses a soft core, commonly lead, surrounded by a casing of harder metal. Full-metal jacketed, lead bullet, or plated bullet load data can be used as long as the following standards are adhered to: The data contains the correct grain weight of bullet. wikipedia has a lot of good info for you under "full metal jacket bullet". Berry's max recommended velocity is not exceeded. (ii) a full jacketed projectile larger than .22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25 percent of the total weight of the projectile. differences between the two ? Keep reading to learn more about FMJ bullets and its uses. this bullet should penetrate just as well as the bullet in the first pic. Both typically have a lead core. Plated vs FMJ. A plated bullet is related to the FMJ, visually anyway. murf Barry’s Mfg suggests that full magnum loads be avoided when shooting plated bullets, keeping muzzle velocities under about 1200fps. It is most commonly used as range rounds and not for self-defense purposes. A bullet jacket generally allows for higher muzzle velocities than bare lead without depositing significant amounts of metal in the bore. Yes Full Metal Jacket bullets will punch holes but there are far better choices for self defense ammo. To create a plated bullet, manufacturers submerge the core in a solution rich in “jacket” material. For gun ammunition, what is difference between FMJBT (full metal jacket boat tail) vs. FMJ (full metal jactet)? In both parts A and B, the regulation is applied to the projectile, in other words, the bullet.
