.277 TVCM (GD/Beretta NGSW Entry)

Overview


.277 TrueVelocity is a polymer composite cased cartridge developed by a Texas based company called TrueVelocity. It is one of three entrants into the 6.8 NGSW program. All three 6.8 NGSW entries are extremely high pressure and designed to push extreme velocities out of relatively short barrel lengths. .277 TVCM as its referred to is designed to be chambered in the General Dynamics/Beretta RM-277 NGSW-R entry. 

.277 TVCM is the highest pressure entrant into the NGSW program and as such it reaches the highest velocities of them all, it is also the lightest thanks to its polymer composite casing.

Each 6.8 NGSW entry cartridge has three different loads, keep in mind - while they are all designed to achieve the same task they will not all perform the same and vary entry to entry:

XM1168 - Full Metal Jacket Ball ammo. Also has a tracer variant.

XM1169 - Special Purpose Match ammo designed for long range shooting. Also has a tracer variant.

XM1170 - Special Purpose Armor Piercing ammo with a tungsten penetrator. Also has a tracer variant.

Additional ammunition types have been created as part of the trials and given unique designations, however beyond 1168, 1169 and 1170 none were requested as part of the NGSW program.

XM1171 HAPI - Special Purpose Hard-Armor-Piercing-Incendiary with a hardened steel penetrator supported by a high temperature incendiary charge. Offered by TrueVelocity as a lower cost alternative to XM1170, removing the need to use Tungsten. Also has a tracer variant.
