Quick Answer
For elk hunting with a 30 Nosler, 180 grain bullets are a popular choice due to their balance between expansion and penetration, but 210 grain bullets can offer deeper penetration and more energy transfer for larger animals.
Choosing the Right Grain Weight
When selecting a grain weight for elk hunting with a 30 Nosler, consider the bullet’s ability to expand and penetrate. A 180 grain bullet typically expands to around 0.5-0.6 inches in diameter, which is sufficient for most elk. However, for larger animals or those with thick hide, a 210 grain bullet may be a better option as it tends to expand to around 0.7-0.8 inches in diameter.
Bullet Penetration and Energy Transfer
A 30 Nosler firing a 210 grain bullet will typically maintain its velocity better than a 180 grain bullet, resulting in deeper penetration and more energy transfer. This is particularly important when hunting larger elk or those with thick hide, as it increases the chances of a clean kill. For example, a 210 grain bullet fired from a 30 Nosler at 300 yards will retain around 1,500 ft-lbs of energy, while a 180 grain bullet will retain around 1,000 ft-lbs of energy.
Field Performance and Terminal Ballistics
When hunting in the field, consider the bullet’s ability to expand and penetrate at varying distances and angles of impact. A 180 grain bullet is generally more suitable for shorter ranges (0-200 yards), while a 210 grain bullet is better suited for longer ranges (200-300 yards). The 210 grain bullet’s deeper penetration also makes it a better choice for hunting in mountainous terrain or when shooting at angles.
