So here’s a visual. This was done a few years ago for deer, and while there are relatively minor differences between a 250lb deer as depicted and a goat, the implications are exactly the same. Three bullets- a 180 Barnes TSX, a 180gr Nasler Accubond, and a Hornady 178gr AMAX were used to illustrate the differences in wound size/tissue damage between a “tough”, “medium”, and “soft” bullet. The three overlays are from those three bullets impacting calibrated ballistic gel through a barrier. Hundreds of deer being shot has proven the wound patterns to be nearly identical in live animals to the test shots shown.
The shaded overlay is the permanent crush cavity- actual tissue damaged and destroyed by the bullets.
180gr Barnes TSX
180gr Nosler Accubond
178gr Hornady Amax
It’s not hard to understand which bullet creates the narrowest wounds, and therefore kills the slowest ON AVERAGE.
