Close-range shooting requires a steady hand and a sight picture that's quick and easy to acquire.
In the video, Kyle Lamb and Craig Boddington discuss the options for close-range shooting with an emphasis on dangerous game enounters.
Close-range shooting was once accomplished with rifles fitted with iron sights. Today, optics have become commonplace and specialized optics are designed to be bright and quick to aim while maintaining plenty of eye relieft.
Shooting at charging targets is excellent practice for many close-range shooting situations and can illustrate how quickly a scope can be when acquiring a target at minimal distances. In many situations, an optic is superior to iron sights due to its ease of use and is easier on aging eyes.
