Description
Hornady .22 ARC unprimed brass gives handloaders a true quality foundation for one of the most exciting .224 cartridges to come along in years. These are new, unprimed cases made in smaller lots to meet strict standards, so you're starting your load development with brass that's consistent from the very first firing. Each case is measured for tight wall concentricity and run through a pressure calibration test to confirm uniform expansion, which translates to steadier pressures and tighter groups downrange.
What Makes This .22 ARC Brass Worth Loading
Uniformity is the whole game with precision brass, and Hornady delivers it in the areas that matter most. Consistent wall thickness, weight, and internal capacity mean your powder charges behave predictably shot after shot. The .22 ARC uses a small rifle primer pocket and carries roughly 34.6 grains of water capacity, giving you plenty of room to push high-BC .224 bullets to velocities that flirt with .22-250 territory out of an AR-15 or a bolt gun.
Dialing In Your .22 ARC Handloads
The .22 ARC is a short, efficient case designed around modern aerodynamic bullets, typically in the 60 to 90 grain range, with a 1:7 twist as the standard. Because the case is shorter than a .223, you can seat those long, heavy bullets without running into magazine length limits. Trim length sits at 1.525 inches and max cartridge length runs 2.260 inches, with a SAAMI max pressure of 52,000 psi. Published load data is available from the usual sources, so working up an accurate recipe is straightforward.
Starting With Fresh Hornady Brass
Buying new, unprimed brass lets you skip the headaches of cleaning and sorting range pickups and get straight to prepping, priming, and loading. For anyone chasing repeatable accuracy from their .22 ARC, this is the dependable starting point that pays off over multiple reloads.

Frequently Asked Questions
Is this Hornady 22 ARC brass primed or unprimed?
These cases are brand new and unprimed. You'll need to add your own small rifle primers before charging and seating bullets. Starting with fresh unprimed brass gives you full control over your load development right from the first firing.
What size primer does the 22 ARC use?
The .22 ARC uses a small rifle primer, which is the same primer size found in most modern .224-caliber centerfire rounds like the .223 Remington. Hornady builds this brass with small rifle primer pockets, so grab your preferred small rifle primers when you set up to load.
Do I need to prep this brass before loading?
Since it's new brass, the heavy lifting of cleaning and sorting is already done for you. Many reloaders still like to run new cases through a quick inspection, chamfer and deburr the case mouths, and check trim length before priming. From there you're ready to prime, charge, and seat.
What bullet weights work best in the 22 ARC?
The .22 ARC is designed around high-BC .224 bullets, with the 60 to 90 grain range being the sweet spot. The short case and standard 1:7 twist let you seat long, heavy-for-caliber projectiles without blowing past magazine length, which is a big part of why this cartridge punches above its size.
