RE: What am I doing different
I guess you are not shooting from a treestand? Like others have said before, try shooting w/ your hunting gear on the way you would be in the woods, if not doing so. Check to make sure your bow is shooting the way it was before you went hunting. I had my bow sighted in perfect and shot my target like a week after season and discovered I was not hitting where I was aiming. Good thing I fixed it b/c I killed 2 does the next week. Are you getting excited and using the wrong pins or misjudging the yardages?
Hope you get it all worked out and Good luck!!
