Black bear, many say, are not hard to kill with good bullet placement. That said, there are bears harvested that reveal previous wounds and occasionally find the errant bullet. Bears are very tough, if not hit correctly.
So for all the easy-to-kill crowd, if you miss vitals, you are not likely to recover your bear, and if you do, you will likely be tracking with dogs for miles. Good luck with that.
With a bigger bore like 45-70, perhaps you will make your bear guide happier too upon recovery.
In my own limited bear experience in 2024, with my 7mm Rem Mag with 160g Nosler Partitions, I hit the front shoulder of a smaller bear quartering towards me and exited on the last rib on the other side. I got blood immediately and the bear went 20 yards. My 7mm was designed for much longer range harvests and it worked but a bit clumsy with a long 26 inch barrel from a treestand shot at 25 yards.

I really would have preferred a more compact fast handling big bore rifle such as the 45-70.
After significant research on YouTube, I saw a review of a new Marlin Lever vs a Henry in 45-70.
Listen and watch.
I likes this comparison video very much! As I said in a earlier piece,
Spring into a Marlin Lever Action Model 1895 SBL 45-70 – Testing Soon
The action on levers, is key. I have placed a deposit on the Marlin Lever Action Model 1895 SBL 45-70.
We shall see…
