I also have a S/W .460 Should be no problem taking out a bear with it. I have a red dot and bipod on it. It’s a tack driver at the rifle range. I’d have to look but I think it’s a 13 inch barrel and it has a compensator. (ammo is a little pricey, if you can get it). 5 shot single or double action and you don’t have to mess with a bolt action of a rifle.
That is a beautiful firearm and I have heard many things about how accurate they are. Mine is just the little 3.5 inch barrel so I don’t have that kind of accuracy but I will say that a paper target will not hold up to many shots at twenty-five yards. It just blows the whole middle out after a few rounds. It also blows everyone else’s targets around from the shock wave. The five yard rolling ring of fire is kind of fun too. One thing is for certain though. Everyone in the range stops shooting when you fire that bad boy! My wrist hurt for a week after running about forty 200 grain rounds through it and another ten 300 grain ones though. There is not an animal in the Americas that could stand up to a .460. I only have black bears around here but I sure don’t have to worry that I have enough firepower.
I don’t think the long barrel ones make the fire rings but here is a video with one of the 3 1/2 inch ones. https://www.thefirearmblog.com/blog/2015/08/07/ring-fire-smith-wesson-460-magnum/
