Not much to worry about....very small likelihood of holding a bear in a 750. Consider the size of the open trap, and then the size of the bears paw. You will not get a full pad catch....at best a toe catch. A bear of any size will pull right out. If not, he'd more likely leave you a toe or a patch of flesh than be there waiting for you.
Every now and then you hear of somebody catch a cub in a number 3....but it's exceedingly rare.
If you do catch one, don't try to release it....just call the warden and let them do it.
