Hunting Bullet Metrics

Apply Terminal Performance Truth


“Time to death after a bullet enters the boiler room is the only conclusive measurement of terminal performance.” – Scott Fletcher

This report presents the observations, data, analyses, and conclusions obtained from a self-funded zebra management hunt conducted in South Africa in July of 2023. The field and skinning-shed data obtained during the hunt confirmed the wound-cavity-based terminal performance concepts and metrics quantified by personal synthetic gel testing and a personal analytical model, called the Guppy, could empirically predict a bullet’s field wounding, penetration, and meat damage.

An abstract summarizing the report’s content can be found on page 2 of the report text. The ten hunt objectives are identified in report section 5.0 found on page 6, and the four specific terminal performance criteria the bullets being evaluated had to meet are presented and discussed in report section 8.0, beginning on page 10. Summary conclusions that sequentially address each of the ten hunt objectives can be found in section 13.0, beginning on page 70.
