Ballistic Coefficient and Trajectory
The ballistic coefficient (BC) of 17 WMR bullets typically ranges from 0.125 to 0.185, depending on the specific bullet design and weight. This BC is relatively high for a rimfire cartridge, enabling the bullet to maintain velocity and resist wind drift over longer distances. As a result, the 17 WMR offers a flatter trajectory compared to many other rimfire options, further enhancing its accuracy and versatility.
