WITH A RIFLE ITS ACTUALLY NOT THAT TOUGH OF A SHOT TO HIT A RUNNING DEER FOR SOMEONE EXPERIENCED AT SHOOTIN DEER ON THE RUN. OF THE 25 DEER I HAVE HARVESTED WITH A RIFLE HERE IN PA 75% OF THEM WERE RUNNING. THE REASON FOR RUNNING IS BECAUSE AFTER THE FIRST DAY THE ONLY WAY MY HUNTIN PARTY HUNTS IS BY DOING DEER DRIVES. VERY EFFECTIVE DURIN MIDWEEK HUNTS WHEN ALL THE WEEKEND WARRIORS ARENT IN THE WOODS
