This led to the development and adoption of the 62-grain bullet, often featuring a steel core for increased penetration.
The difference in weight directly impacts the bullet’s ballistic coefficient (BC), which is a measure of its ability to overcome air resistance. A higher BC indicates that the bullet will retain its velocity better and be less affected by wind drift. Generally, a heavier bullet, like the 62-grain, will have a higher BC than a lighter bullet, like the 55-grain. This means the 62-grain bullet will typically maintain its velocity better at longer ranges and be less susceptible to wind drift.
It’s important to recognize that the specific performance characteristics of each bullet weight can vary depending on the manufacturer, bullet design, and powder load. Some 55-grain bullets may be designed for maximum velocity and fragmentation, while others may prioritize accuracy and controlled expansion. Similarly, 62-grain bullets can range from those designed for barrier penetration to those optimized for hunting applications. Factors like bullet construction (full metal jacket, soft point, hollow point, etc.) also play a significant role in determining the bullet’s overall performance.
Therefore, when evaluating the difference between 55-grain and 62-grain ammunition, it’s essential to consider not only the bullet weight but also the specific design and intended purpose of the ammunition.
