This ends in much less bullet drop, making it simpler to precisely have interaction targets at prolonged distances with out extreme holdover corrections. The 6.5 Grendel, whereas nonetheless providing glorious long-range capabilities, might expertise barely extra bullet drop at excessive ranges.
Wind Drift
Wind drift is the diploma to which wind impacts a projectile’s path. The extra aerodynamic a projectile, the much less it’s affected by wind. The 6mm ARC, with its sleeker bullet design, typically displays a slight benefit by way of wind drift resistance. The 6.5 Grendel, whereas nonetheless performing properly in windy circumstances, might require barely extra windage changes at longer distances.
Vitality Switch at Impression
The vitality switch at influence is a important issue, significantly for searching. The 6.5 Grendel, typically makes use of projectiles with higher sectional density than the 6mm ARC. This contributes to superior vitality retention over distance. The 6.5 Grendel is extra more likely to retain sufficient vitality at longer distances to make sure efficient enlargement and terminal ballistics. Nevertheless, the 6mm ARC also can ship ample vitality at influence relying on the load, bullet selection, and the vary to the goal.
