Hornady 81539 Superformance 22Arc 70Gr Cx 20 Per Box/10 Case
The Hornady 81539 Superformance 22 Arcane ammunition delivers a significant velocity boost—up to 200 fps faster than conventional rounds—without the typical penalties of magnum loading. Built around a 70-grain CX bullet, this round is engineered for shooters who want measurable performance gains from their .22 Arcane rifle without cranking up chamber pressure, recoil, or muzzle blast. Whether you're hunting varmints or running precision drills at distance, Superformance ammunition lets your rifle do more with the same platform.
The secret is Hornady's progressive propellant technology. Instead of burning like standard powders, these compounds meter their energy release in stages, accelerating the bullet to higher velocities while keeping breech pressures, felt recoil, and temperature sensitivity in check. That means reliability across seasons and climates—critical if you're working far from the range or in variable conditions. You also get the consistency that modern hunting and target shooting demands: no flyers, no surprises, just repeatable performance box after box.
This ammunition is loaded with Hornady's CX (Copper Solid) bullet, a monolithic copper design that combines penetration with reliable performance. Each box contains 20 rounds, and you can order in convenient 10-box cases. The 22 Arcane is a modern intermediate cartridge gaining traction among shooters who appreciate its ballistics and efficiency, and Superformance ammo maximizes what the platform delivers.

Frequently Asked Questions
What makes Superformance ammunition faster without higher pressure?
Hornady's progressive propellant burns in stages, releasing energy more efficiently through the barrel. This design accelerates the bullet to higher velocities while keeping chamber pressures, recoil, and muzzle blast comparable to conventional loads.
Is this ammunition safe for semi-auto rifles?
Yes. Superformance ammunition is safe for all firearm actions, including semi-autos, lever guns, and pump actions.
What is a 70-grain CX bullet and what is it used for?
The CX (Copper Solid) is a monolithic copper bullet designed for consistent penetration and reliable performance. It's effective for varmint hunting and target shooting where controlled expansion matters.
Will this ammo perform reliably in cold weather?
Yes. Superformance ammunition is formulated for consistent performance across a broad range of temperatures, so you can count on reliable velocity and accuracy whether you're shooting in summer heat or winter cold.
