Considerations & Trade-offs
- Flat-base flat-nose bullets are a specialized profile, so they’re best suited to rifles and loads that are set up for this style rather than a broad range of applications.
- The exposed lead front is part of the design, which may be a consideration for hunters who prefer a different bullet nose configuration.
- At 255gr, this is a heavier .377 caliber option, so it may not fit every shooting setup or intended use.
- Packaged 50 per box, which is practical for load development and hunting use, but not a high-volume quantity for extended practice.
