Description
Peterson Cartridge built its name on brass that precision reloaders can trust straight out of the box, and this unprimed 260 Remington case with a large rifle primer pocket is a strong example of that reputation. Made in Pittsburgh by a family-owned American company, these cases are produced on a modern case line with the kind of attention to weight, wall thickness, and internal volume that matters when you are trying to stack rounds into the same hole. The 260 Remington shares much of the ballistic character of the classic 6.5×55 Swede but fits a short action, which is a big part of why it keeps showing up at matches and in the deer woods alike.
What Sets This Peterson 260 Rem Brass Apart
Each case comes annealed from the factory, which helps set uniform neck tension and extends usable case life across more reloads. Reloaders regularly report real-world life in the range of 10 to 14 firings under normal loads, with more possible when you stay on top of annealing. The large rifle primer pocket here is the standard setup for the 260, giving you broad primer availability and reliable ignition. Peterson also stamps lot numbers on the packaging, so tracking brass through your load development is easy if you keep your boxes organized.
Getting the Most From Your Peterson 260 Remington Cases
This is unprimed brass, so you are supplying your own primers, powder, and bullets. As with any premium brass, internal case capacity can differ from other makers, so it is smart to back off your charge a touch and work back up when switching over. Many reloaders run these cases with little to no prep beyond a quick inspection, though some like to lightly chamfer and deburr the case mouths before the first seating. The reusable plastic ammo box keeps everything protected on the bench and in your range bag.
For PRS, F-Class, long-range hunting, or any build where consistency drives accuracy, this Peterson 260 Rem brass gives you a reliable foundation to develop a load you can count on.

Frequently Asked Questions
Is this Peterson 260 Remington brass primed or unprimed?
These cases ship unprimed, so you will supply your own primers, powder, and bullets. They are set up with a large rifle primer pocket, which is the standard configuration for the 260 Remington and keeps primer selection easy. Just prime, charge, and seat as part of your normal reloading process.
Does the brass come annealed from the factory?
Yes. Peterson anneals the case necks during production, which helps deliver uniform neck tension right out of the box and supports longer case life. That factory annealing also means you can load the first firing without annealing beforehand.
How many times can I reload Peterson 260 Rem brass?
Reloaders commonly see around 10 to 14 firings under normal load pressures, and that number can climb higher with regular annealing and good case care. Actual life depends on your load pressure, sizing setup, and how hard you push things. Keeping charges reasonable and annealing on a schedule is the best way to stretch case life.
Can I use my existing 260 Remington load data with this brass?
It is best to treat it as a new component rather than a drop-in swap. Premium brass like Peterson can have different internal case capacity than other makers, so start a bit below your established charge and work back up while watching for pressure signs. A quick inspection and a light chamfer and deburr on the case mouths before the first seating is a good habit too.
