joshua 35 whelen,
I have this gun is a 5 inch barrel...I would not recommend it for bear in a hunting mode. Perhaps if you where in a stand over bait it might be ok.
It is not as "hot" as a 41 mag that is hand loaded. A good heavy load in
a 41 mag is using a 250 grain plus hardcast bullet and is loaded fast. There is no load that will compete with this in a 10 MM 610.
A minimal cartridge for black bear for me would be 44 mag with 300gr hardcast bullets, but I feel that a 454 Casual or the new 460 would be a far better choice.
There are far better sources on this topic than me, but I strongly feel that the 10mm is too small for a black bear.
hth,
Fred
