Description
The .375 EnABELR is one of the newer kids in the extreme long range world, and this Peterson brass is the real foundation for it. Dreamed up by Bryan Litz of Applied Ballistics alongside Derek Peterson, the EnABELR line was built from scratch to push heavy, high-BC bullets way out there. The name itself tells the story: Engineered by Applied Ballistics for Extreme Long Range. What makes it interesting is that this is a true original design with no parent case, so you are not sitting at the bench forming brass from something else. It shows up as purpose-made cases ready to prep.
What Makes This .375 EnABELR Brass Worth It
Peterson has a reputation among precision reloaders for a reason. Their cases run tight on case wall consistency, primer pockets, and flash holes, which is exactly what you want when ignition and velocity need to repeat shot after shot. Lower runout and uniform case dimensions mean you can chase that last bit of accuracy without fighting the components. For a cartridge that lives and dies at a thousand yards and beyond, that kind of repeatability matters more here than almost anywhere else.
Reloading the .375 EnABELR the Right Way
These ship unprimed, so you pick the large rifle magnum primer that suits your powder and load workup. The wider, shorter case design was the whole point, letting powder burn more efficiently and cutting down on unburned powder fouling in the bore. Peterson brass is known for holding up through multiple firings when you treat it right, so a little attention to trimming, annealing, and neck prep goes a long way toward getting plenty of reloads out of each case.
Peterson .375 EnABELR Brass for Serious ELR Builds
This is specialized stuff for a specialized cartridge. If you are putting together an ELR rig chambered in .375 EnABELR, or already running one and need fresh brass, this is the proper starting point. Made in the USA by a family-owned shop that lives and breathes match-grade casings.

Frequently Asked Questions
Does this Peterson .375 EnABELR brass come primed?
No, these cases ship unprimed. That lets you select the primer that matches your powder and load development. The .375 EnABELR uses a large rifle magnum primer.
Do I have to form .375 EnABELR brass from another cartridge?
Not with this brass. The EnABELR was designed as an original cartridge with no parent case, so Peterson produces it as purpose-made .375 EnABELR cases. You skip the fire-forming and conversion work and get straight to prepping and loading.
What is the .375 EnABELR designed for?
It was developed by Applied Ballistics and Peterson for extreme long range shooting with heavy, high-BC .375 projectiles. The shorter, wider case design was built to burn powder efficiently and feed long bullets, making it a favorite for dedicated ELR rifle builds.
How many reloads can I expect from Peterson .375 EnABELR brass?
Peterson brass is known for holding up through multiple firings when cared for properly. Staying on top of trimming, annealing, and keeping pressures reasonable will stretch case life. Match-grade consistency also means the brass stays dimensionally stable across those firings.
