Generally I agree that many people should keep handgun hunting under 100 yds. BUT,,, many of us practice a lot,, know how to properly shoot at longer distances,, AND are willing to pass on a less than good presentation. Remember,, handgun silhouette shooters shoot at 200 meters AND have to knock down a heavy steel target.
I have personally taken an elk at 156 yds,, with a single shot Contender, with a heart shot,, also with a 20-30 degree uphill angle. The elk did not run, it fell right there. I have also taken quite a few whitetails at distances over 100 yds with a handgun.
BUT,,, I also pass on a lot of shots if I do not think I can make a clean ethical kill. Biggest whitetail I ever had in my sights locally was allowed to walk. He never presented me with the type of shot I needed. He was also within 40 yds of me at one point.
I understand the thoughts about getting closer & all. Heck, I teach hunter safety,, but I stress the fact you need to make sure you can honor the animal with a clean ethical killing shot.
And if you really want to see a great study on handgun hunting,, read the story of our own "sixshot" on his African safari,, where he took 3 animals with a handgun. Including a Cape Buffalo. His Zebra dropped in it's tracks so fast,, the PH didn't see it fall. (And there were several other people in his camp who used rifles & lost or wounded game to where it had to be tracked long distances.)
There are MANY of us who enjoy handgun hunting,, and we strive to be the best we can at it.
My point being is a rifle is not the "magic" firearm. It's just a tool, just as a handgun is. It's HOW it's used & how a hunter approaches the hunt. And many, many handguns and their hunters are very capable of serious hunting beyond 100 yds.
