But for pistol, for sure that 45 Super (depending on the load) meets the 500 ft-lbs at 50 yards CO requirements for big game. This one I have checked and re-checked.
I don't know what Voodoo you pulled to get 1000 ft lbs of energy at 100 yards out a ballistics calculator. I put in 14K feet of elevation and none of the 185-230 grain loads using the MV given by bullet weight from BBTI reached anywhere near it. 800 ft lbs was about the best it could do. To get the 1000 ft lbs at 100 yards I had to up the MV by 200+ fps.

I'll agree some Super loads do meet minimum requirements to hunt with a handgun in Colorado. However you're going to have to use a pistol with a 5" or longer barrel to get the necessary velocity to keep the energy at 500+ ft lbs at 50 yards according to what JBM spits out with the BBTI numbers.

Elmer Keith killed a huge Mule Deer at 600 measured yards. His companion wounded it at closer range with a 300 H&H. He shot 4 times, missing twice. At pistol pressures, you're not going to get the additional velocity in a longer barrel that you think. For any of my 12 pistols or revolvers, I don't shoot farther than what I can keep in 8".

It was wishful voodoo.

Yep you were right, out of a carbine, per gundata.org I just checked and it never reaches necessary ft-lbs at 100yds to be legal for big game in CO with rifle.

But yes, we agree that interestingly 45 Super does meet the requirements for big game hunting in CO with handgun. 4.6" barrel length of a Glock 21 puts me there.
