Quick Answer
The .308 Winchester is a suitable caliber for small deer, offering a balance between power and penetration, but it's essential to consider the deer's size and the hunter's skill level. A .308 can be effective, but over-penetration is a risk, and a larger caliber might be more suitable for larger deer. Proper shot placement is crucial.
Choosing the Right Bullet
When using a .308 Winchester for small deer, it’s essential to select the right bullet. A 150-160 grain bullet with a ballistic coefficient (BC) of 0.5 or higher is a good starting point. This weight and BC combination will provide sufficient penetration and expansion, reducing the risk of over-penetration. The Remington Core-Lokt and Winchester Power Point are good examples of bullets that meet these criteria.
Shot Placement and Angles
Proper shot placement is critical when hunting small deer with a .308 Winchester. Aim for the center mass, about 1-2 inches below the shoulder, to ensure a quick and humane kill. When shooting from a treestand or elevated position, consider the angle of descent and adjust your aim accordingly. A 20-30 degree angle is generally safe, but this may vary depending on the terrain and deer size. Always ensure a clear shot and a solid rest to compensate for any movement.
Considerations for Smaller Deer
When hunting smaller deer, such as fawns or yearlings, a .308 Winchester can be an overkill. In these cases, consider using a smaller caliber, such as the 6.5mm or 7mm, to minimize damage and ensure a quick kill. However, if a .308 is the only option, make sure to use a heavier bullet (180-220 grains) with a higher BC to compensate for the smaller deer’s size and reduce the risk of over-penetration.
