In the Dec. issue of Fur-Fish-Game magazine there is what I consider to be a pretty decent article by Ed Hall on measuring stopping power by the Taylor KO Factor. The equation is basicly weight X velocity X bullet diameter equals momentum as opposed to the usual velocity squared X weight equals energy.
However; there are usually two sides to any coin. So, does anybody have any thoughts or insights, yea or nay on this KO concept???

If it's what I'm thinking of, the theory has been around quite a while? Mostly an African concept? Seems like you need to factor in bullet construction. I don't believe soft points figure in the formula, or am I way off base?
Good hunting. LB

I think that Leonard is correct. The "KO" factor is likely to be a good one for large, dangerous Game where bullets must penetrate and break large bones. A bullet through both shoulders of a cape buffalo for instance.

Yeah, he's the guy out of Africa.
Bullet design was something that I was wondering about. By his formula, a full metal jacket would count the same as a soft point or a hollow point???? I still think the article has merit though.

Taylor's KO system was an attempt to predict how long an elephant hit near the brain with solids (of course)would be rendered unconcious. That's all it was ever supposed to be, and didn't work for that since nobody has been able produce any repeatable results.Frequently, there are no results at all.
Somehow, the theory that didn't work has been reapplied, with softs, on thin-skinned game, with body hits. Even Taylor wrote that boring old kinetic energy was a better indicator of effectiveness in these cases.

Perhaps unfair for me to comment without benefit of reading the article. However, at first blush, the author may have drawn a blank on a provocative subject for this month and chose the Taylor Formula to tweek and modify? I haven't brained all that many elephants so I defer to his experience. If he did what previous wtiters claim that he did; Mr Taylor wouldn't recognize the concept as his, I'm hazzarding a guess?

I didn't read the article either, my comments were about the KO theory itself, and it's misapplication. Taylor tried to put a number on what many people already knew; that large caliber, heavy bullets of sufficient velocity had a better chance of dropping elephants that had non fatal noggin hits than smaller calibers. My own elephants were shot with body hits, so I'll accept that.
The same doesn't apply in other uses.I've shot smaller animals with my elephant rifles, and the results aren't that impressive compared to rather ordinary deer rifles. Any theory that doesn't consider bullet construction isn't worth much.
