Yep, if we've cow called our way to the bull we stay with a sharp cow sound to stop or slow him up, if he was brought in or we went to him via bugling then we use a bull sound to stop or slow him up. At times a 2nd shot can be had but at minimum you do your best to reduce tracking distance, hopefully he's a dead elk walking! A lung shot bull can cover 300 yds & sometimes blood tracking him is not easy if the shot was high & you're in the thick stuff.
