Related: Wadcutter (WC) – Wadcutters have wider, flatter meplats than SWC. Where a rounded tip would slide through a target, the flat tip (“meplat”) punches a big hole. JSPs are considered a good middle ground between a hollow point (HP) and a semi-wadcutter (SWC, below).ĬONS: Greater muzzle velocity than HP Semi-Wadcutter (SWC) It also fouls up the barrel of a firearm less than non-jacketed bullet. This causes it to expand upon impact – creating a greater surface area. Unlike a full metal jacket that completely encases the bullet in a coating of metal alloy, the soft point leaves a portion exposed. It can also sometimes be called a “partially jacketed bullet”. This is a bullet with an exposed lead up. Related: JHP+P+ – Overpressurized Jacketed Hollow Point is a combination of a jacketed hollow point’s increased damage to soft tissue with the increased velocity and penetration of a +P round. Some handguns deal with the added stress of overpressurized ammunition quite well. The end product is faster muzzle velocity and greater penetration. This is ammunition made with a higher pressure than the standard rounds of its caliber. Related: Non-jacketed hollow points (HP) Overpressurized Ammunition (+P) This means less lead powder coating the inside of the barrel.ĬONS: Decreased penetration in steel and concrete. The jacketed version just has a thin covering of copper or steel. Because the bullet expands inside the soft target, it pushes out a larger surface area of tissue. It looks a mushroomed gob of lead pushing through. When a hollow point strikes its target, the hollow causes the bullet to deform. Hollow point rounds have a hollowed out center. PROS: Less mess than an unjacketed bullet.ĬONS: Greater penetration – less expansion in soft tissue.
Full Metal Jacket (FMJ)įull metal jacket (FMJ or FMC) refers to the copper or steel alloy coating on the bullet to reduce lead residue left in the barrel after firing. We can’t cover everyone, but we will try to cover the most common varieties.
In this article, we’ll go over a few of the different types of ammunition available. And in the bullet family tree, every round is related by at least a first or second cousin. With each ‘ pro‘, there’s usually a ‘ con‘. In a self-defense situation, some bullets can give an advantage.
There are a lot of different types of bullets out there. MHRA 'SPB', All Acronyms, 6 January 2022, Bluebook All Acronyms, SPB (Jan. SPB, All Acronyms, viewed January 6, 2022, MLA All Acronyms. Retrieved January 6, 2022, from Chicago All Acronyms.
