.300 SAUM Extended Ballistics (to 1,000 yd)

At 1,000 yards, .300 SAUM (165gr at 3075 fps, 100 yd zero, standard conditions) has a modeled come-up of about 38.3 MOA / 11.1 MIL, retaining 1048 fps (subsonic).

Range (yd)	Velocity (fps)	State	Drop (in)	Elev (MOA)	Elev (MIL)
300	2266	Supersonic	-11.5	3.7	1.06
400	2028	Supersonic	-26.8	6.4	1.86
500	1805	Supersonic	-50.6	9.7	2.81

Extended predictions beyond 500 yards are modeled from the same G1 engine — useful for initial DOPE, but outside the 500-yard manufacturer-table validation audit. Confirm with observed DOPE, especially near transonic.

Hunting Energy Reference

Retains at least 1,000 ft-lb (deer-sized energy reference) through 500 yd — the end of the listed data.
Retains about 1,500 ft-lb (elk-sized energy reference) to roughly 400 yd.

A retained-energy reference only — not a shoot/don't-shoot distance. Real effective range depends on your accuracy, shot placement, bullet construction, and conditions. The ~1,000 ft-lb (deer-sized) and ~1,500 ft-lb (elk-sized) figures are commonly cited rules of thumb, not standards.

Data & Sources

Representative load: 165gr Remington Core-Lokt Pointed Soft Point

Your barrel, ammunition lot, and conditions will differ — always verify against the manufacturer's data and your own rifle.

Overview

The .300 SAUM is a hard-hitting short .30-caliber magnum built to deliver long-range big-game performance from a lighter, shorter rifle than a standard belted magnum requires. It drives .30-caliber bullets at high velocity, giving it the flat trajectory and downrange energy suited to elk, large deer, and open-country shots at extended distance. Its fat, efficient case earned a following among handloaders and long-range shooters who valued its accuracy potential, but recoil is stout for the platform's weight. Because it was outsold by the .300 WSM, factory ammunition and rifles are comparatively scarce, and it is today largely a handloader's and enthusiast's cartridge rather than a mainstream choice.

History

Remington introduced the .300 Short Action Ultra Magnum in 2002, alongside its 7mm counterpart, as a beltless short magnum shortened from the .300 Remington Ultra Magnum and ultimately descended from the .404 Jeffery case. The design packed near-full-magnum .30-caliber ballistics into a case short enough to run in a compact short-action rifle. It arrived to compete with Winchester's .300 WSM, which had launched a year earlier and went on to win the marketing battle and broader factory support, leaving the .300 SAUM the less common of the two short .30 magnums.
