Its why the 308 is absent from this test. 6mm ARC vs 6.5 Grendel. I was lucky enough to get my hands on one of the first CMMG Endeavor 300 6mm ARC AR-15 Rifles, and it has been awesome to shoot! The faster a bullet leaves the barrel, the farther it flies before hitting the ground, the less it deflects in crosswinds, and the more energy it carries when impacting the target. Its a 6mm cartridge similar to 6.5 Grendel, built for the AR-15 platform, Its optimized for bullets in the 103 grain 110 grain range, Its got more velocity and less recoil compared to 6.5 Grendel, It shares the same parent case with 6.5 Grendel: The 220 Russian, Its capable of launching a 6mm 108 grain projectile approximately 2800 FPS from a 24 barrel, BARREL: 20, 1:7.5 twist, 6mm ARC, MT 416SS, SBN, MUZZLE: MUZZLE: SV Brake, threaded 5/8-24, GAS PORT LOCATION: Rifle Length with SLR Adjustable Gas Block, RECEIVER: Forged 7075-T6 AL M4 type upper, AR15 type lower, FINISH: Cerakote Receivers and Hand Guard, Find a cartridge similar to 6mm ARC thats supported in the, Determine the 6mm ARC case capacity for my lot of brass (H2O method), Adjust Quickload model for case capacity and any other factors, Model loads looking at pressures and velocities (using 6mm PPC load data as a backup sanity check), It shares the same parent case with 6mm ARC (the 220 Russian), Its case capacity is very close (1.9 grains of H2O different), Likely in reference to a 24-ish test barrel, No AR gas system present to reduce velocity, Start with observed 20 velocity data for my H-4895 load (2,631 FPS), Look at the QuickLoad projected velocity difference between a 20 and 24 barrel, Add the velocity difference to the actual measured velocity, Account for ~1.18% reduction in velocity (calculated from my 224 Valkyrie AR-Bolt side by side testing) due to the AR-15 gas system, I had limited components available to test, results could get better from here (more velocity with less pressure), These loads may be hotter than what will function reliably in a typical AR-15 (and may not be safe), I will follow up with testing of Hornadys factory ammunition with the 108 grain ELD-M bullet.
