Knockdown Power.... Fact or Myth?

As always it depends on your definition of "knockdown power" and that is the challenge in this exercise.
Change the definition, change the answer.

The folks that study this stuff have identified over half a dozen elements and measurements seeking to quantify the elements of "killing power". In most cases someone from the other side can make some sort ofargument against what is offered, hence hardly worthwhile to dive into that brain damage.

I will say this though ---going for something more fundamental....
Leaving out CNS shots, hunt the same game species multiple times under challenging field conditions (no blindhunting)firstusingweaponry with light bulletsandnarrow calibers and then do the same with the heavy bullets and wide calibers (medium velocity or better).Whenyou're done observing many well aimed shots and the corresponding differences in the game's "reaction to impact", then I am confident you will know (ata very fundamental,base level) the difference in what Ipersonally call "knockdown power."

When the sound you hear come back to you from the impact on game isakin to a5 pound sledge striking a saddle pommel following a full house swing, then you know you're getting there.... K-THUD.

IMHO, one of the more notablebenefits of ample "knock down power" becomes apparent when thingsaren't just right/or don't go just rightand you're on a mission to go out there and get'er done sometime before next week because it is a 5 day season and that bad boy isn't "whitetail posing" properly.
