The double versus bolt never fails to get a good debate going. Firstly I enjoyed the video and found the comparison interesting. It would be my belief that most professionals that use these type of rifles practice little and I would think plenty go through a season without firing a shot. I think most tough situations are won by the shooters ability to stay calm, not get off as many shots as possible and that for me marks the true professional. I found on the odd occasion it has occurred and compared to others little experience, that the hardest thing was to wait until the target was close enough that the one shot was going to find its mark and do its job. Its fun to compare double v bolt but if the first two havn't done the job your likely dead. The fact that there is so much debate on it tells me that its that close as to not really matter otherwise the argument would have been settled years ago.
