3. Projectile Type
Projectile type significantly influences the terminal performance of 405-grain .45-70 loads. Lead bullets, particularly with flat or round noses, represent traditional choices for this cartridge, impacting terminal ballistics, trajectory, and overall effectiveness on game. Understanding the relationship between projectile type and performance is crucial for ethical hunting and accurate shot placement.
Lead, as a projectile material, offers several advantages. Its malleability promotes expansion upon impact, transferring kinetic energy effectively to the target. This expansion creates a larger wound channel, increasing the likelihood of quick, humane harvests. Additionally, lead’s density contributes to high sectional density, enhancing penetration, particularly important for larger game animals. Flat-nosed projectiles maximize energy transfer at shorter ranges by creating a wider wound cavity, while round-nosed projectiles offer slightly improved ballistic coefficients, potentially extending effective range. Hunters often select flat-nosed bullets for larger, tougher game at closer ranges, reserving round-nose bullets for situations demanding slightly flatter trajectories.
Modern alternatives, such as jacketed hollow points, exist but may not function optimally in all .45-70 rifles, especially those designed for traditional lead bullets. The .45-70’s relatively low velocity, compared to some modern cartridges, sometimes necessitates careful projectile selection to ensure reliable expansion. Selecting an appropriate projectile type, whether a traditional lead flat-nose or a round-nose design, directly affects terminal performance. This consideration, combined with an understanding of the intended game and hunting conditions, ensures ethical and effective harvesting.
4. Typical Use
The combination of hunting and lever-action rifles forms a cornerstone of the 405-grain .45-70 load’s enduring relevance.
