Hornady Superformance 300 Win Mag 165gr CX – 20rd Box

Description

Hornady built Superformance around a simple concept: get more speed without asking your rifle to work harder. The 165 grain CX load does exactly that, running at 3260 fps and generating nearly 3900 foot-pounds of energy downrange. For hunters working medium to long-range shots, that velocity buys you a flatter arc and less wind deflection than traditional loads in the same caliber.

What Sets the CX Bullet Apart

The copper alloy construction here means no lead core, which appeals to hunters in lead-restricted areas but also delivers real performance benefits. The solid copper-zinc construction won't separate on impact, maintains excellent weight retention (around 95 percent), and the Heat Shield tip keeps the ballistic coefficient consistent throughout the bullet's flight. This matters more than it sounds when you're planning shots past 400 yards.

Superformance Propellants Do the Heavy Lifting

Hornady's progressive powder formulation is what allows this load to achieve high velocity without pushing peak pressures into risky territory. You get better performance from your rifle, full stop. No extra recoil, no temperature-related velocity swings that would mess up your zero between seasons, no excess fouling in the barrel. The brass cases and Boxer primers mean these are reloadable too, if you go that direction down the road.

Built for Real-World Hunting

With a 165 grain bullet at magnum velocities, this round sits in that sweet spot for deer, elk, and similar game out to meaningful distances. The flatter trajectory means less guessing on holdover. The penetration and expansion balance works because the CX opens reliably even at distance without over-expanding and losing effectiveness on tougher game. Twenty rounds per box gives you enough to shoot and practice with before heading to the field.
