For about 5 years on and off, I've used a Mini-14 loaded with bulk Wolf 55-grain HP. I dropped a 7 pointer at 60 yards, but I did have a doe get away last year. I don't know how far away the doe was, and she was on the run when I shot her.
A couple of years ago, I was hunting with the sunrise. I had 5 deer come into a clearing and dropped all 5 with 5 boiler room shots.
You took at shot at a deer that you didnt know how far away it was AND it was running???
