Here is a shot at 2025 yards. Of course I miss but it was interesting reaction from the animals. If your computer will tolerate the 720 pixel High Def. then you can see the bullet strike in the second video and it is dead on even in the wind but I make an error in range because of my not double checking how far the small buck was. No need to run the first video in HD.

I watched one of my snipers break the Americal/Chu Lai Sniper School record one day with a M21. It was a peculiar circumstance and he was extraordinarily good with a rifle.
