![]() Imagine a bullet arcing through a six-inch diameter pipe for a certain distance.Įffective range in this test is the minimum impact energy recommended for a humane kill on medium game, such as deer and antelope (1200 ft-lbs.), large game, such as elk and moose (1500 ft-lbs), and the minimum velocity most hunting bullets require for reliable expansion (1800 fps). MPBR is the distance over which a bullet rises three inches above sight line and then drops three inches below to hit within a six-inch kill box. Trajectory in this test is defined as Maximum Point Blank Range (MPBR), uncorrected for accuracy (MOA). Note: Hand loaders can achieve much better performance in many instances. All categories were corrected to standard atmosphere at sea level (59F/15C and 29.92 inHg/1013 mbar) Muzzle velocities are the nominal industry standard for the tested bullet weight in each caliber for factory-loaded ammunition. Specialized long-range bullets were not used for this test as they are unnecessary for most hunting situations. 450, or higher, make bullets fly flatter and drift less in cross-winds. BC quantifies a bullet’s aerodynamic efficiency, and SD predicts relative ability to penetrate into a game animal. Both BC and sectional density (SD) are noted for each bullet tested.
