Quick Answer
Using lighter bullets can actually increase the effective range of the 33 Nosler, allowing for flatter trajectories and less drop at longer distances due to its high ballistic coefficient. However, this may also reduce kinetic energy, affecting its terminal performance. The ideal solution depends on the specific hunting scenario.
Bullet Weight and Range
The 33 Nosler is a high-performance cartridge designed for big game hunting at extended ranges. When using lighter bullets, typically in the 250-270 grain range, the effective range can increase due to the reduced drop and wind deflection. For example, a 250-grain bullet at 3000 FPS will exhibit less drop at 500 yards compared to a 300-grain bullet at the same velocity.
Ballistic Coefficient and Trajectory
A higher ballistic coefficient (BC) is essential for a flat trajectory, and the 33 Nosler excels in this regard. With a BC of 0.725 for a 250-grain bullet, it will maintain a flatter trajectory than a 300-grain bullet with a lower BC. This is particularly important at longer ranges where even small differences in drop can impact the hunter’s ability to place a shot.
Terminal Performance
While using lighter bullets can increase the effective range, it may also reduce kinetic energy (KE) at impact. The 33 Nosler generates significant KE even with lighter bullets, but hunters should consider the specific hunting scenario and the animal’s size and distance to ensure sufficient penetration. A 250-grain bullet at 3000 FPS still delivers approximately 2700 ft-lbs of KE, which is more than sufficient for most big game hunting applications.
