I bought my son a HR 243 last year. His first deer he ever harvested was with that 243 a 9 pt that scored 131 3/8. He hit like you are suppose to right in the shoulder and out the other. The deer ran about 50 yards with not a drop of blood on the ground. We have another member of our lease that his daughter took her first doe two weeks ago and again hit it great. That deer did not have a blood trail either. They both are shooting the remington corlock 100gr bullet. Is that just the nature of a .243 cal?
