Loyalist84,
You already have all the gun you need. The 9.3X62 has been used successfully on every big game animal on earth since 1905. The original factory load was a 286 gr bullet loafing along at 2150 fps. About 20 years later the standard loading had the same bullets plodding along, ... 2360 fps. Those are the loads that built the reputation of this great cartridge.
Today we have guys who routinely load the 9.3 to well over 2500 fps with the same weight bullet, but it really is not needed at the ranges you would need to be engaging any critters. I have personally used the 9.3X62 in a number of rifles for close to four decades now, and have only ever had one animal, and it was not a bear, get up after being hit with a 270-290 gr bullet from one of those rifles. Moose, big mountain caribou bulls (which are the size of mature elk), black and grizzly bears, all succumb pretty quick. I still have and use a few 9.3X62s, and feel very comfortable carrying one anywhere in The North.
Your Husqvarna was designed for comfortable carry and quick and easy handling, the most important facets of what you will be experiencing should you take on this responsibility. As well, the 9.3X62 is a very accurate cartridge, and easy to control in recoil, which is important in building your confidence in the rifle.
You are about to become a professional. Rather than spending money on a new outfit, spend it out on dates getting to really know that old sweetheart. Take her out often! Practice, practice, practice! Do lots of dry-fire practice too, lots of it! Carry it every time you have an opportunity. Shoulder it, aim with it, swing and sight instinctively with it, climb with it, hike with it, take it on fishing trips.
Above all, settle on one load and stick with that. The last thing you want to be doing is trying to remember what round you have in the chamber.
Best,
Ted
