Factory ammo at this point. Looking into handloading but have to save that for next year probably. I have seen a few black bears in the woods but not during hunting season yet, and I may never draw an elk tag. I will probably only really use it for deer but I would like to be able to take a bear if I had the opportunity. I am just wondering if a bullet suitable for deer will also make an honest, ethical kill on a large bear from this gun out to 30 yards. I'm more of a rifle and bow guy and I have complete confidence that my regular setup will handle a bear if I do my part. This is my first pistol so I'm not sure what the parameters are. The reading I have done seems more comparable to a crossbow than a compound bow. Very deadly but with a very definite range at which your equipment will provide adequate performance. Or, most compound bow's are way more capable that most archers, however most compound setups are done at 40-50 yards, even though any rifle shooter will "feel" confident far beyond what the shorter, lighter, bolts need to be shot at game.
