Description
Core-Lokt ammunition in 7mm Rem SAUM gives you all the ballistic performance of a full magnum from a short-action rifle without excessive recoil or the headspace inconsistencies that come with belted cases. The 150-grain pointed soft point travels at 3110 fps and carries enough energy to handle mid-range to extended hunting situations effectively. If you already own a SAUM rifle, you know how well this cartridge bridges the gap between classic magnum power and modern short-action efficiency.
What Makes Core-Lokt Reliable
The Core-Lokt bullet has earned its reputation through 85 years of field use, not marketing. The tapered copper jacket is mechanically locked to a solid lead core in a way that controls expansion predictably. When the bullet enters game, the soft point initiates the process, and the tapered jacket design ensures the core stays put rather than separating. You get roughly 2X expansion with strong weight retention, which means the bullet reaches vitals and does its job from impact to exit.
7mm SAUM Ballistics in Practical Terms
The SAUM cartridge delivers near-magnum performance from a short, handy rifle. With a 150-grain bullet at 3110 fps, you're looking at roughly 3221 foot-pounds of energy at the muzzle and a ballistic coefficient of 0.346. That's flat enough for hunting from moderate distances to 300-plus yards depending on your zeroing and skill. The cartridge headspaces off the shoulder rather than a belt, so you get more consistent chamber pressure from shot to shot and better long-term case life.
Loading and Case Quality
These are factory-loaded rounds with brass cases, non-corrosive boxer primers, and full reloadability if you want to stretch your ammunition investment over time. Remington includes 20 rounds per box, which makes them convenient for hunting trips or range verification before the season.

Frequently Asked Questions
How does the 7mm SAUM compare to the 7mm Remington Magnum?
The SAUM delivers nearly identical ballistics to the full Magnum but in a short-action package, meaning faster cycling, less recoil, and better handling in the field. The SAUM headspaces off the shoulder rather than a belt, which gives you more consistent case life and tighter pressures across multiple reloads. The main tradeoff is ammunition availability, as the SAUM has fewer factory options.
Will Core-Lokt ammunition work well for elk hunting at range?
The 150-grain Core-Lokt PSP is effective on elk inside 300 yards or so, where energy remains well above what's needed for deep penetration and vital-area damage. Beyond that, you're relying on precise shot placement and familiar rifle handling. For longer-range elk hunting or tougher situations, many experienced hunters prefer heavier bullets or bonded designs, but this load is solid for standard hunting distances.
Is the pointed soft point or round-nose version better for hunting?
The pointed soft point (PSP) in this load is the modern standard and offers flatter trajectory and faster expansion at range compared to round-nose designs. For hunting at typical distances, the PSP is the better choice. Round-nose Core-Lokts still work great at closer ranges and are favored by some northeastern hunters, but PSP is more versatile across different hunting scenarios.
Can I reload these brass cases?
Yes, these brass cases are fully reloadable and hold up well across multiple loading cycles since they headspace off the shoulder rather than a belt. Norma and Alpha Munitions (ADG) brass is commonly used for SAUM reloading, and quality Remington brass performs similarly when you're careful with headspace management during the reload process.
