2amencw has this "spot-on"...
Mleake you must of been awake for the lesson....
Colorado Lawmakers should pull there heads out and do some real research before they start making laws that have no aplication to true knowladge.
I have to add that those that preach Muzzle Energy have no clue what really kills... This is a formula for ammo manufactures to push the latest and greatest, and the clowns that run our state depts. It is complete non-sence!! Good for misleading those that have never shot an animal.
Case in point I once shot a Whitetail doe with a
50 BMG the boolit just passed through its lungs and it raised its head and looked around. It then went back to grazing
I thought I had shot high...Several minutes passed before she started acting strange and fell over.
So much for the 12,000 lbs. of muzzle energy pretty obvious that energy has little to do with it
TKO is a much better formula... V x Weight in grs.x Dia./ 7000 (gr. to the lb.)
45acp.. . 800fps x 230gr. x .452 =83168 divided by 7000= a KO value of 11.9
The 357 magnum that was taken to Wyoming and used to kill Grizzly, Moose and Elk when it first came out has a KO of 11.2 with a 158gr. at 1400fps
