Description
The 27 Nosler is a lot of cartridge. Built on the .404 Jeffery case with much of the body taper removed, it holds roughly 43 percent more powder than a .270 Winchester and pushes a 150-grain bullet north of 3,250 fps out of a 26-inch barrel. That kind of pressure and case capacity is exactly where quality brass earns its keep, and Peterson's 27 Nosler casings are made to handle it firing after firing.
What Sets This Peterson 27 Nosler Brass Apart
Every Peterson case is made in Cranberry Township, Pennsylvania and held to a match-grade standard from the raw material through final inspection. That means tight tolerances on weight, wall thickness, and concentricity, plus a lot-to-lot consistency that lets you develop a load once and trust it. Reloaders who have run Peterson across other calibers routinely find weight spreads inside a couple grains, uniform neck thickness, and flash holes that need little to no cleanup. It stacks up honestly against the premium imports without the sticker shock.
Loading and Prepping Your 27 Nosler Cases
These are large rifle primer cases, which is the standard setup that works with common reloading gear and no rifle modifications. The necks come annealed for uniform neck tension and longer case life, and the flash holes are deburred, so a lot of folks load them straight out of the box after a quick check. The 27 Nosler runs slow-burning powders like RL-26, RL-33, H1000, and IMR 7977 under high-BC .277 bullets, and it likes a large rifle magnum primer to light those heavy charges cleanly. First-firing brass growth is even, so a light trim to bring the lot into spec is about all the fuss you'll deal with.
Who Reaches For 27 Nosler Brass
This is a western hunter's cartridge and a long-range shooter's toy. Mule deer, elk, antelope, and open-country shots where a flat trajectory and retained energy matter are right in its wheelhouse. Start with quality brass and the 27 Nosler will reward careful load work with the kind of low ES and SD numbers that keep hits on target way out there.

Frequently Asked Questions
Does this Peterson 27 Nosler brass use large or small rifle primers?
It uses standard large rifle primers, which is Peterson's standard configuration for this cartridge. That means it works with common reloading equipment and doesn't require any rifle modifications. For the heavy powder charges the 27 Nosler runs, a large rifle magnum primer is the usual recommendation to get clean, consistent ignition.
How much case prep does the 27 Nosler brass need before loading?
Not much. The necks come annealed and the flash holes are deburred, so many reloaders load it after just a quick inspection and a light trim to uniform length. Running a mandrel or sizing die through the necks to set consistent neck tension is a common step, but you won't be fighting burrs or wild weight variance out of the box.
What powders and bullets work best in the 27 Nosler?
The 27 Nosler is a large-capacity case that likes slow-burning powders such as Reloder 26, Reloder 33, H1000, and IMR 7977. It shines with long, high-BC .277-inch bullets in the 150 to 165 grain range thanks to the cartridge's faster 1:8.5 twist barrels. Pair those heavy charges with a large rifle magnum primer for the best results.
How many times can I reload Peterson 27 Nosler brass?
With sensible load pressures and proper care, Peterson brass commonly gives around 8 to 12 reloads. The annealed necks help maintain uniform neck tension over the life of the case, and the consistent primer pockets tend to hold up well. Your actual case life depends on how hot you run your loads and how carefully you size.
