I can't think of any hunters who haven't shared your pain, it happens. One of the best bucks I have taken I clean cut missed on a gimme shot, I ended up harvested that buck a few weeks later in the same location. I had my first ML hangfire in 15 plus years of smokepole hunting this year, just so happened to be on a big whitetail. Missed opportunities are part of the game! Fall off, get right back on and ride again.

Best of Luck
