Hunting construction
Soft-point, bonded, partitioned, and monolithic expanding bullets are designed differently. Their intended impact-velocity ranges and use cases come from the bullet or ammunition manufacturer.

Know the exact name
.280 Remington is identified by its complete cartridge designation. The resource-table alternative is 280 Rem. A caliber number, bullet diameter, or family resemblance on its own does not identify ammunition compatibility.
7mm Express Remington is not 7mm Remington Magnum. .280 Ackley Improved also has its own specification.
Dimensions: open the exact dimensional drawing ↗. The displayed number is bullet maximum, rather than an assertion that every manufactured projectile or barrel has this exact diameter.
Origins & evolution
Remington introduced the .280 in 1957 in the Model 740 autoloading rifle. The underlying 7 mm-.30-06 idea was already familiar to wildcatters, but the factory introduction gave it a standard cartridge and ammunition supply. It later appeared in pump-action and bolt-action Remington rifles as well.
The cartridge’s commercial history became unusually complicated by naming. In 1979 Remington briefly tried the 7 mm-06 name, then used 7 mm Express Remington before returning to .280 Remington. The 7 mm Express wording created confusion with the separate 7 mm Remington Magnum, while the earlier .270 Winchester and the Magnum both competed for hunters’ attention. Those decisions help explain why a capable sporting cartridge did not achieve the visibility its supporters expected. The later .280 Ackley Improved belongs to the same broad lineage, but records another design rather than another of Remington’s historical marketing names.

Construction changes the story
Soft-point, bonded, partitioned, and monolithic expanding bullets are designed differently. Their intended impact-velocity ranges and use cases come from the bullet or ammunition manufacturer.
Open-tip match and tipped match bullets prioritize consistency and aerodynamics. A match designation does not by itself mean the projectile was designed for hunting expansion.
Lead-free, reduced-recoil, and premium long-range products are separate load designs when offered. Compare the exact SKU, bullet weight, test barrel, and intended role rather than relying on a cartridge-wide average.
In the cited .280 Remington examples, bullet weights are 140, 150 grains. These are the weights actually present in this source selection, not a claim that every possible loading is listed.

Changing bullet weight also often changes bullet design and propellant choice. Two curves are comparisons of the listed products, not a controlled experiment proving that bullet weight alone caused the difference. Catalog downrange points are projections under the maker’s conditions; barrel-study points are recorded observations in the study firearm.
Direct answers
A long-action 7mm-class sporting cartridge. Its historical alternate name 7mm Express Remington can appear on older boxes or firearms.
The cited dimensional standard lists 0.2845 inches (7.226 mm), bullet maximum. This drawing convention is different from a casual caliber nickname.
7mm Express Remington is not 7mm Remington Magnum. .280 Ackley Improved also has its own specification.
The downrange view uses the exact manufacturer catalog records shown in the source table. Dashed connectors and intermediate inspector values use linear interpolation between the displayed source points. Calculated energy uses the listed bullet mass and velocity.
Energy is calculated from mass and velocity. It does not establish accuracy, expansion, penetration, pattern density, recoil, or suitability for a particular firearm. Use the exact product documentation and firearm manual.
Trace the facts
Compiled by 2A Ledger from the linked standards, manufacturer publications, and identified test records. Checked October 18, 2026. Historical tests and older catalogs retain their original dates; a listing here does not establish current availability.
Diameter figures preserve the cited drawing convention. Inch–millimeter conversion uses exactly 25.4 mm per inch. Factory specifications describe the maker’s test setup; your firearm, ammunition lot, temperature, and measuring method can produce different results.
