Quick Answer
The .30-06 is generally considered a better choice for bear hunting due to its slightly wider range of effective shot distances and a more forgiving recoil.
Ballistic Comparison
When it comes to hunting bears, a cartridge’s kinetic energy at 200 yards is crucial. The .30-06 and .308 Winchester have similar performance profiles, but the .30-06’s larger case capacity allows for heavier bullets and slightly higher velocity. This results in a .30-06 delivering 1,600 ft-lbs of kinetic energy at 200 yards compared to the .308’s 1,500 ft-lbs.
Recoil and Control
Both cartridges are suitable for hunting, but the .308’s lower recoil makes it a better choice for hunters who need to shoot multiple shots quickly. A 7-pound rifle with a .308 cartridge can produce around 14 ft-lbs of recoil, whereas a similar 7-pound rifle with a .30-06 can produce around 22 ft-lbs of recoil. This extra recoil can lead to missed shots, especially for inexperienced hunters.
Real-World Application
In a real-world scenario, a hunter is more likely to encounter a bear at 50-100 yards. At these close ranges, both cartridges can deliver a fatal shot. However, the .30-06’s slightly wider effective range means a hunter can be more confident in their shot placement at longer distances. If a hunter is unsure of their shooting abilities or is hunting in areas with longer shot opportunities, the .30-06 is a better choice.
