I left out the part about using a PDA to use software which predicts trajectory..... this is the key to reaching out that far and getting on target fast.
You can do things like that if you are doing southern beanfield type shooting, but I don't do that type of hunting
Most of all my shots are well under a hundred yards.
In fact my favorite hunting round is a 308 win, however some of my hunting is done in northern BC while grizzlies are still out and about
For this area I prefer more punch then what a 308 can give
