Thought you might be interested to see this photo-sequence from one of the details in the Group 3 Nitro event
at the Australian National Big Game Rifle Championships held in Darwin, Northern Territory, a couple of weeks ago.
Group 3 rifles must be over .485 calibre and generate a minimum muzzle energy of 5,300 ftlbs!

When I figure out how to edit .mov files, I'll toss a couple of clips to NitroX to host here somewhere.
