I agree it is about perfect. 8" circle mid body behind shoulder ='s dead bear everytime.
I've seen way too many bears wounded and not recovered. A single lung hit bear will NOT be recovered.... No doubt at all.
Wait for a broadside or quartering with the front leg forward. If your hunting bait take your time, there is no need to hurry. Calm down and wait for the perfect shot. Anything less is just not ethical.
Good luck, you will love Canada.
