i was out hunting today, posted by a treeline and along came this average sized doe. I waited till it was broadside to me and it was about 20 yards away. I shot and it started running, i thought forsurely that i had hit it but there was no blood, ect. I was using a 30-30 150 grain, i sited it in at 75 yards and was shooting in a 5 inch circle consistantly.

any ideas of what might have gone wrong? I am positive i did not hit the deer.
