Wisconsin black bear. What your guess for size?

Getting some action to my bait site. I don't have a lot of experience judging black bears. Any idea by looking at these photos? Not even sure if its the same bear hitting the site or multiple.

The bear in the 3rd pic appears to be a smaller bear, but the bear in 1,2, and 4 is a nice bear. It's hard to tell without reference, but he looks like he might weigh 300 lbs.
