That is a dandy Ken !
Stuff happens ,I think most have had one or two of those wanting to heave moments ... and anyone it hasn't happened to yet hasn't hunted much . Every animal,it's movement at any given.....actions...reaction be different . We have to be prepaired and ready should something like this happen, and it will....Always have # 2 ready and easily accessible . You owe it to the animal.......
Congratulations on a beautiful animal my friend..and being a good finisher ..enjoy the many gifts given.
