A projectile including a first section and a second section. The first section and the second section being snapped together at a snap together interface having a pressure angle of at least 75 degrees. The first section and the second section forming at least one cavity therebetween, with a payload contained in the cavity.

Various embodiments of optimized subsonic projectiles are provided. For example, one exemplary subsonic projectile can include an elliptical nose cone, a cylindrical body and a boattail with various design features that can be used in a subsonic ammunition cartridge where the subsonic projectile is stabile throughout at least a segment of a flight allowing for better accuracy, maintaining low drag, maximizing range and achieving desired performance while ensuring the projectile stays below the speed of sound and lowering a noise profile of projectile and a launcher firing the projectile.

A method for making an improved projectile 360, 460 by defining a discontinuity, groove or trough in a distal ogive section of the projectile to provide an external ballistic. effect uniforming surface feature (e.g., nose ring groove 369, 469) which makes an unsupported gap in the ogive profile that beneficially affects the flow of air over the front half of the ogive. The improved bullet's external surface discontinuity feature (369 or 469) creates effects in the flowfield that dominate any dynamic effects from bullet-to bullet manufacturing inconsistency and resultant differences in dynamic behavior.

A novel castable frangible projectile and techniques for manufacturing such are provided. A cartridge system includes a case defining a volume, a propellant disposed in the volume of the case, and a projectile coupled to the case. The projectile includes a body disposed at least partially within the case and configured to enclose the propellant within the volume of the case. The body is formed of a castable eutectic mixture, the castable eutectic mixture configured to be melted and cast, wherein the body is configured to break into a plurality of fragments upon impact with a target.
