Karl, I think once you have done it you can't do it again
- well I can't anyway !!!

I remember my 2 main ones.

one was a Cow buff that was running away, then turned
and came straight for me. I got down on one knee and waited until she got to 15 yards and then fired. Hit her in the neck and turned her.

I wouldn't say it was slow motion but it seemed a while
for her to get real close.

2nd was a Scrub bull that i was chasing parrallel and it heard my mate shout, turned and came at me from 22 yards. I had the gun up and fired, 1 shot, forehead just above and left of the eye, it dropped stone dead within 8 yards from where it started the charge. Quickest snap shot I have ever done and can still clearly remember seeing it's bulging eye in the scope before I fired.

I will say that both times I had tunnel vision, very focussed and was damn glad I had thought through and practised what I would do in that situation - and it worked !!!
