Actually,
you brought up ethics in the article. Reread it, or read my quote of it. Had you not used that particular word, I probably wouldn't be typing this right now.
Yes, I've read the 800 ft-lb figure, but in any literature that was worthwhile it has always been in reference to that amount of energy needed to drop a deer in it's tracks.
Do you see a distinction between instantly dropping a deer and just humanely dispatching a deer?
The 800 fpe figure widely accepted as the mimimum necessary to humanely take deer-sized game is nothing new at all
OK here is the hitch. Replace the words "humanely take" with the words "instantly drop" and I think your statement will be more accurate.
The .44 Magnum is also "widely accepted" as an adequate cartridge for dispatching deer with a handgun. Generally, hunters would not consider it cruel to use a .44mag to take deer out to 100 yards. Yet the .44 makes around 850 ft-lbs
at the muzzle of a 7" bbl. And only 650 fpe at 100 yards.
So, on the one hand we have a community of hunters who "widely accept" 800 fpe as a minimum to humanely take deer. But that same community of hunters seems to think it is perfectly humane to dispatch deer with a .44 magnum? (I won't even tell you that a .357magnum is also an accepted cartridge)
Hogwash!
I think some confusion occurred over what was considered enough to instantly drop a deer and somehow that got mistaken as "Canon Law."
Here is the way I see it:
I don't believe you need to drop the animal in it's tracks to be "humane". If the deer expires within a few seconds that's about what I consider humane. Remember, a deer can cover a lot of ground in a few seconds. A healthy human can cover 100 yards in 10 to 15 seconds, a lungshot deer can do that much faster.
So using death-within-a-matter-of-seconds as the humane criteria - you can get by with a lot less than 800 fpe. A .44 Mag can do it, a .50 roundball can do it, an
arrow can do that.
