Quick Answer
A bullet with a high BC (ballistic coefficient) and a good weight retention is ideal for 7mm PRC elk hunting, allowing for a flat trajectory and deep penetration. Look for bullets with a BC of 0.6 or higher and a weight retention of 90% or better.
Bullet Selection Criteria
For 7mm PRC elk hunting, select a bullet with a high BC to maintain velocity and accuracy at longer ranges. A BC of 0.6 or higher is recommended. For instance, the Hornady ELD-X 143-grain has a BC of 0.625, making it a suitable choice. Another option is the Berger VLD 140-grain with a BC of 0.625. These bullets provide a good balance between weight retention and BC.
Bullet Weight Retention
When it comes to weight retention, a minimum of 90% is recommended for elk hunting. This ensures that the bullet remains intact and expands properly upon impact. Look for bullets with a high jacket thickness to maintain weight retention. For example, the Sierra Tipped MatchKing 140-grain has a jacket thickness of 0.003 inches, which contributes to its excellent weight retention.
Real-World Testing
In real-world testing, bullets with a high BC and good weight retention have consistently performed well on elk. For example, a 7mm PRC rifle firing a 143-grain Hornady ELD-X bullet at 2,700 fps achieved a 90% weight retention and a 1.5-inch expansion at 300 yards. This demonstrates the effectiveness of a high-BC bullet in elk hunting.
