The 257 Roberts sometimes makes use of bullet weights much like the Weatherby Magnum, starting from about 87 grains to 120 grains. Whereas the bullet choice is comparable, the velocities are notably completely different. The .257 Roberts, with its smaller powder capability, achieves extra modest muzzle velocities, usually within the vary of two,800 to three,000 fps. This distinction interprets right into a barely extra curved trajectory and fewer power downrange. Nonetheless, the 257 Roberts greater than compensates for this in different facets, as we will see.
A Aspect-by-Aspect Comparability: Charting the Ballistic Variations
To completely grasp the disparities between these two cartridges, it is vital to create a comparability. Think about a situation utilizing normal, well-performing bullets for every:
| Characteristic | 257 Weatherby Magnum | .257 Roberts |
|---|---|---|
| Bullet Weight | 100 grains | 100 grains |
| Muzzle Velocity | 3,400 fps | 2,900 fps |
| Velocity at 200 yards | 2,900 fps | 2,450 fps |
| Vitality at 200 yards | 1,850 ft-lbs | 1,330 ft-lbs |
| Bullet Drop at 300 yards | -8.5 inches | -13.5 inches |
Because the comparability desk exhibits, the 257 Weatherby Magnum maintains superior velocity and flatter trajectory throughout all distances. It delivers considerably extra power downrange. These ballistic distinctions are essential for understanding the suitable functions of every cartridge.
Actual-World Efficiency: Placing Them to the Take a look at
Past the uncooked numbers, the sensible functions of those cartridges present one other essential facet for evaluation. The place do they honestly shine, and the place do they fall quick?
Reaching Out: Efficient Vary and the Hunt
