Description
The Remington Core-Lokt 300 Rem SAUM 165-grain load brings decades of proven hunting ammunition design to one of the most efficient short-action magnum cartridges. If you're running a rifle built on the compact 300 SAUM platform, you know it bridges the gap between velocity and rifle manageability in a way full-length magnums can't match. This ammunition harnesses that platform with a bullet design that has filled more hunting tags than any other factory load.
Core-Lokt's controlled expansion philosophy centers on a tapered copper jacket mechanically locked to a solid lead core. That lock matters. Upon impact, the jacket controls expansion in a way that retains weight while generating wide wound channels at moderate ranges. With the 165-grain PSP configuration, you get a bullet engineered for medium to large game at practical hunting distances. The pointed soft point design also brings ballistic advantage compared to traditional soft point profiles, allowing the flat trajectory of the SAUM to work at its best.
What Makes the 300 SAUM Core-Lokt Configuration Effective
The 165-grain weight sits in the sweet spot for the 300 SAUM platform. Factory loads from Remington push this bullet to 3075 fps from a full-length barrel, maintaining excellent velocity retention to extended distances. That velocity matters for shot placement because flatter trajectories mean tighter hold corrections on uneven ground or between solid cover. The caliber itself was designed for hunters who wanted magnum performance without the length and weight penalties, and this load respects that design intent.
Reloading Opportunity Built In
Remington loads Core-Lokt ammunition on reloadable brass with standard primers, making this a practical choice if you reload. Component retention means you can stretch every box's value beyond the initial firing. The 165-grain Core-Lokt bullet itself has built a reputation for straightforward, predictable performance—users regularly report sub-half-MOA accuracy and consistent field results without the premium pricing of bonded bullets. That combination of performance and value keeps this load in consistent circulation among hunters who understand what Core-Lokt delivers.

Frequently Asked Questions
What game is the 300 SAUM 165-grain Core-Lokt suitable for?
This load works well for deer and elk-sized game at moderate ranges. The 165-grain Core-Lokt performs reliably on animals weighing between 90 and 150 kg. For heavier game like moose or extended long-range work beyond 400 yards, hunters often favor heavier bullets or bonded construction designs, though this load is still capable with proper shot placement.
How does the Core-Lokt bullet design handle impact?
Core-Lokt's tapered copper jacket is mechanically locked to a solid lead core. Upon impact, the jacket expands in a controlled manner while the lock prevents jacket/core separation. This design typically delivers around 2X expansion and retains approximately 60-70% of original weight, generating wide wound channels while maintaining penetration for medium to large game.
Can I reload Core-Lokt brass?
Yes. Remington loads this ammunition on reloadable brass cases with standard large rifle magnum primers. Many handloaders specifically purchase Core-Lokt factory loads as a value source of quality brass for developing their own 300 SAUM loads.
How does the 300 SAUM compare to other magnum cartridges?
The 300 SAUM delivers ballistics similar to the 300 Winchester Magnum but in a shorter action, making rifles lighter and easier to handle. It excels in compact rifles like the Remington Model 7 while still providing flat trajectory and extended-range capability. The trade-off is slightly lower ammunition availability compared to the more popular 300 Winchester Magnum.
