Lot's of folks have given you some food for thought. Your original question asks what the limits of your setup are. Whitetail deer, no problem. Small to medium sized hogs, no problem. Probably not enough to reliably get through the shield on a very large hog. As far as bear go, I haven't shot one, so it is only what I have heard from others, that with a well placed arrow they aren't much more difficult to kill than a deer. As others have said, elk are pretty much tougher than deer, but with a qood shot if everything goes well it will get the job done. Just very little margin for error. This doesn't pertain to you original question, but you have a long time before next elk season, and a young healthy guy should have no trouble getting a little more power behind their setup if they want to. For some perspective, I hurt my shoulder early in the summer yanking a saddle off of a bucking horse. Ended up messing up my AC joint and had a couple minor rotator cuff tears. Had surgery around 2 weeks ago to have the rotator cuffs touched up and the end of the clavicle of my string side resected. I shot around 100 arrows with my 50# thunderchild today. I see that you have shot heavier bows in the past but feel more accurate with the lighter setup. Definitely gotta shoot what you feel confident, but with more time with a little more poundage, I would be surprised if you wouldn't get comfortable with a heavier poundage if you have your heart set on hunting elk. No matter what you decide, I wish you luck and hope that you enjoy your bow. He makes great bows.
