28 Nosler Load Development: A Practical Guide

The 28 Nosler is a fast, beltless 7mm magnum that fits a standard-length action and throws high-BC bullets flatter and faster than almost anything in its class. It is a long-range hunter’s cartridge — and a barrel burner — which is exactly why finding a settled load and stopping there matters.

Why the 28 Nosler rewards a settled load

Its large case drives 160–195-grain 7mm match and hunting bullets at high velocity, so a good load holds energy and bucks wind far downrange from a rifle that still fits a standard action. The trade-off is throat wear — it is not a cartridge to burn on an endless ladder, so clean data that names your load quickly is worth real money in barrel life. A fast twist keeps the heaviest, highest-BC bullets stable.

What shooters reach for (starting points)

• Powder: Reloder 26, Reloder 33, Retumbo, H1000 and Vihtavuori N565/N570 are popular 28 Nosler powders; the big case wants slow-burning magnum powders — match them to your bullet weight and barrel length.
• Bullets: 160–168-grain hunting bullets (Nosler AccuBond Long Range, Hornady ELD-X) for game, and 175–195-grain high-BC match bullets (Berger 180/184/195, Hornady 180 ELD-M) for reaching out; the heaviest hold wind best.
• Brass: Nosler, ADG and Peterson make good 28 Nosler brass; uniform, well-prepped brass tightens your velocity spread before you touch the load.
• Primers: large rifle magnum — Federal 215M, CCI 250 and similar light the big charges consistently.

The process — same as any cartridge, 28 Nosler flavored

1. Pick your components and look up the published min and max for that bullet/powder pair.
2. Run a powder ladder. Load a few charges across the safe range and chronograph them to find the velocity flat-spot — the charge window where small powder changes barely move velocity. How to read a powder ladder →
3. Run a seating-depth test at your chosen charge to tune how the bullet jumps to the lands and tighten the group. How to run a seating-depth test →
4. Confirm at distance and record your dope, so the load proves itself where it counts — a fast magnum earns its keep at distance, so confirm the load and its dope where you actually hunt or compete.

Let the data pick your best load

The hard part isn’t shooting the ladder — it’s reading it honestly. Import your chronograph CSV (Garmin Xero, LabRadar, MagnetoSpeed) and your target groups, and Loadscope scores every charge and seating depth on velocity flat-spot, velocity SD, mean radius and vertical, then names your best load and prints a pocket range card. No retyping velocities, no eyeballing which charge won. How the scoring works →
