Quick Answer
Yes, there are significant recoil differences between .308 loads. While the .308 Winchester is generally considered a moderate-recoil cartridge, variations in powder load, bullet weight, and case capacity can affect the overall recoil experience. Some loads can produce as little as 15 ft-lbs of recoil, while others can exceed 25 ft-lbs.
Load Characteristics and Recoil
Recoil in a .308 rifle is primarily influenced by the powder load, with heavier loads producing more recoil. For example, a 150-grain bullet loaded with 42 grains of IMR 4064 will produce about 17 ft-lbs of recoil. In contrast, a 165-grain bullet loaded with 50 grains of H4350 will produce around 22 ft-lbs. This difference of 5 ft-lbs can be significant, especially for less experienced shooters.
Bullet Weight and Recoil
Bullet weight also plays a significant role in determining recoil. Generally, lighter bullets tend to produce less recoil than heavier bullets, due to their lower mass. However, this relationship is not linear, and the effect of bullet weight on recoil can be influenced by other factors, such as powder load and case capacity. For example, a 140-grain bullet loaded with 40 grains of IMR 4064 will produce about 15 ft-lbs of recoil, while a 150-grain bullet loaded with the same powder will produce about 17 ft-lbs.
Practical Considerations
When selecting a .308 load for hunting, it’s essential to consider the recoil characteristics in relation to the shooter’s experience and ability. For less experienced shooters, a load with lower recoil may be preferred, while more experienced shooters may opt for a load with more recoil for its increased accuracy and stopping power. In general, a 150-grain to 165-grain bullet loaded with a moderate to heavy powder load is a good starting point for most .308 rifles.
