Some good footage in the video but I suppose all it goes to show is that in all cases the shooter was not successful with his first shot although if watching closely at least one sequence shows the animal dropping on the first and the second was probably not needed.

I can well imagine that a video could be made up of both the first and second shot from doubles not being successful and this is the reason why at least some if not all of the PHs who have met their maker or been seriously injured recently has occurred (I don't know what weapons all were using but it has been revealed at least some had doubles.

I have done enough hunting and shooting including many years trap and skeet to know that if you miss with your first there is no guarantee you will be successful on the second, in fact it could be argued that if you do miss the first then you are possibly not quite set or concentrating and this condition can still follow over into the second attempt.

As to speed, well there are several video footages around showing very fast recovery and reloading on close in charges with bolt guns where the animal has been dropped just like in the video starting this thread.

Gryphon says it well and all too true "One thing to note is that there are so many that cannot handle either configuration too well".

Still absolutely nothing wrong with the double and it has it's place in DG hunting but it is not necessarily going to guarantee success or survival anymore than a good well handled bolt gun, 'well handled' being the key words with whatever weapon we choose.
