Peterson Cartridge built its name on doing one thing and doing it right: brass. This bulk box of 250 unprimed 27 Nosler cases is made in the USA by a family-owned shop that dedicates its entire facility to turning out some of the most consistent rifle brass available. For anyone running the fast, flat-shooting 27 Nosler, that kind of lot-to-lot uniformity is exactly what you want when you're stretching things out past 500 yards.
The 27 Nosler is a serious long-range hunting round, built on the .404 Jeffery case with roughly 42 percent more capacity than the .270 Winchester. It pushes a 150-grain bullet north of 3,300 fps and a 165-grain AccuBond Long Range around 3,150 fps out of a 26-inch barrel, which makes it a true standout among .277-caliber cartridges. That performance leans hard on quality brass, since big case capacity and high pressures put real demands on the cases you feed it.
Peterson starts with premium C260 cartridge brass drawn into tubes through a multi-step press process, then forms the neck and shoulder, punches and preps the flash hole, and gives the neck and mouth an induction anneal so the case grips the projectile properly. The result is brass with consistent weight, uniform wall thickness, and tight dimensional tolerances. Reloaders routinely report long case life from Peterson cases, with many firings before they show their age, which helps stretch the value of a bulk box like this one.
These cases arrive unprimed and annealed, ready for your preferred load workup. As with any virgin brass, it's smart to check your cases, run them through your sizing die to set shoulder bump for your chamber, and give the necks a quick chamfer before seating bullets. Start low and work up your charge, especially if you're coming from a different brand of brass where case capacity may differ. Grab your large rifle magnum primers, your powder of choice, and a quality .277 bullet, and you've got everything you need to build a load this cartridge deserves.
These cases arrive unprimed and annealed with the flash hole formed and consistent dimensions. Most handloaders still run virgin brass through a sizing die to set shoulder bump for their specific chamber and give the case mouths a quick chamfer before seating bullets. A little prep goes a long way toward getting the most out of them.
The 27 Nosler uses a large rifle magnum primer. The big case capacity and heavy powder charges this cartridge runs call for that hotter, magnum-rated spark to get a complete, consistent burn.
Peterson Cartridge dedicates its entire facility to making brass, which translates into tight tolerances for weight, wall thickness, and concentricity. For a high-capacity, high-pressure round like the 27 Nosler, that consistency pays off in velocity uniformity and longer case life. Shooters frequently report many firings before these cases need to be retired.
Yes. Case capacity and primer pocket dimensions can vary between brands, so any change in brass should be treated like any other component change. Drop your charge a bit and work back up to your target load while watching for pressure signs.
