True Velocity Polymer Cased Ammo - Innovative or Problematic?

The RM277, a bullpup rifle developed for the NGSW program, showcases advanced polymer-cased ammunition (.277 TVCM) offering significant weight reduction and high performance. Its unique 'Short Recoil Impulse Averaging' system effectively halves felt recoil, while selectable open/closed bolt operation enhances versatility. Ballistics and barrier tests reveal impressive penetration and energy transfer.

The GBRS Group, comprised of former Navy SEALs, compares the M4 Carbine to the Sig Sauer M7 (NGSW). While acknowledging the 6.8mm round's superior ballistics for long-range and armor penetration, they find the M7's increased weight and recoil make the M4 more suitable for most assault missions due to its maneuverability and familiarity. The M7 is described as a powerful 'broadsword' compared to the M4's agile 'katana'.

This video discusses the U.S. military's adoption of the new 6.8x51mm cartridge, branded as the .277 Fury, for its Next Generation Squad Weapon program. The change is driven by a need for a more effective round against modern threats, particularly those with advanced body armor, addressing perceived deficiencies of the 5.56mm and 7.62mm calibers in recent conflicts. The shift signifies a departure from decades of standardization.

The Sig Sauer MCX Spear, the civilian version of the U.S. Military's M7, is a versatile and accurate battle rifle chambered in .308 Winchester. It features a unique side charging handle, an adjustable gas system, and demonstrated sub-MOA accuracy with Federal Premium 168gr ammunition. While reliable, some gas blowback was noted when suppressed in a prone position.
