Most of my 44 magnum kills were made with revolvers. But I did own a Browning M92 years ago and I killed deer, bear and antelope with it. It did just fine. The 92 would not feed the very wide bullets like the LBT 300 and 320 grain WFNs, nor would it work with the Keith SWCs because the cartridge length was too long. So I ended up using an LBT 265 grain WFN gas-check bullet, and a Hornady 265 grain jacketed for that carbine.
I can tell you from experience that the 44 mag with proper bullets is ok for big deer because I have personally killed them with 4 inch, 6.5 inch, 7.5 inch, and 8-3/8" barrels on revolvers.
I have used 44 magnum revolvers to kill 3 bears, several elk, about 2 dozen deer, 4 antelope, one bison, and several horses as well as about 3 dozen cattle. With hard cast bullets of 240 to 320 grains I have never seen a single problem killing any big game or domestic animal with a 44 magnum.
