Well, I don't have any experience with the bear bomb sow in heat lure, but I do have experience with sow in heat lure.
I have used it for a few years now with great results on big boars, once the rut is in full swing, big boars don't want anything to do with food.
Just ask Tony, "Maine Guide" on here, last year he was hunting from a ground blind & had a monster boar come to the bait broadside at 7 yards, first thing he did was put his nose to the ground where I squirted some sow in heat lure, I'll let him tell what happened.....................LOL!
