Shooting Running deer.
I am going on a deer drive this weekend and I have rarely shot at a running deer. What are some tips or ways to shoot running deer. Should I shoot a .300 Savage w/ a scope or a 30-30 w/ open sights. I really don' t think 30-30' s have that much power. I was on a deer drive this past weekend and shot at a deer 4 times and missed every time.(w/ a scope) and so did my friend. You don' t have to lead them do you?
