Description
Hornady’s Custom line in 6mm ARC with the 90-grain CX bullet is built for hunters and practical rifle shooters who want a single load capable of handling both medium-sized game and extended-range work from a compact AR-15 platform. The 6mm ARC was designed from the outset to push high-BC projectiles from a short action, and pairing it with a 90-grain bullet sits in a sweet spot where sectional density is high enough for reliable penetration on deer-sized animals without the steep velocity penalties that heavier bullets can bring in shorter barrels.
The CX bullet is Hornady’s monolithic copper alloy design. Because it has no lead core to shed, it holds together across a wide range of impact velocities, which matters when shots vary from close ranges where velocity is highest to the longer distances where the 6mm ARC genuinely excels. The polymer tip initiates expansion at lower velocities than an exposed-lead design would, extending the useful range of the bullet. Bearing surface is reduced compared to traditional cup-and-core projectiles of the same weight, which tends to keep chamber pressure in check and can benefit accuracy in barrels with tighter-than-average throats.
Brass-cased and loaded under Hornady’s Custom specifications, each round is intended to deliver consistent muzzle velocity and uniform neck tension from shot to shot — the kind of consistency that shows up in group sizes at distance rather than on a chronograph screen. For 6mm ARC rifles used in hunting seasons where shot opportunities are limited, a load that performs predictably on both ends of the ballistic arc is worth the premium over bulk practice ammunition. Boxes contain 20 rounds.
