It has happened to me twice and the last timewas this year. It was the first really cold morning, I had a nice 9 ptr broadside 25yds out. I tried three times to get the bow back and the third time I got it back and the arrow popped off the string. I made the mistake of not re-nocking each time I tried to draw back. WhenI got back home I lowered my draw weight 4lbs. and resighted the bow.

I understand about muscles getting tight and extra clothes hindering the draw... but I also wonder if bow limbs stiffen on cold mornings thereby increasing the draw weight of the bow???
