Hey, Brian
I does happen. I missed a 3X4 coues this year and I am not sure why either. I do know that I needed to spend alot more time at the range. I like to know where my rifle is hitting at 100 yrds and also at 500 yrds. And yes the shaking factor does come sometimes. You never know I know a few guys that have drawn good bull tags 2 years in a row. Good Luck
