yes these cats wont usually come into the open like a coyote,they also like the bird sounds or more high pitched sounds and cat sounds you can get bobcat sounds for your PM and as YD3 said they probably wont charge in,but they may,they usually just are setting by an object that you have saw a bunch of times,but this time there is a cat by it.If you have ever seen them in the woods they can sit or stand dead still but that short tail is always working and moving.They depend on sight and sound almost always,they don't circle down wind,if they approach from down wind then thats just where they were when they heard the sound.Good Luck,around here a big tom is about like killing a B&C buck,a highly admired trophy,I've only killed 2 of them and they were small 15lbs each.I called in a nice tom with a mouth call during nov.deer season,but I missed(bear recurve and wooden arrows)but that cat jumped straight up in the air when that arrow hit just above him by an inch or two,I think I scared one of his lives out of him.Post pictures if you score and good luck!!!
