Had a doe within 10yds this morning. I shot and saw my arrow fly really crazy. Looked down and my nock was on my string. Fortunately it only gave her a slight haircut across the brisket and not a gut shot. I got down and found my arrow broken in two. I grabbed another from the quiver and pulled on it and the nock slid right out. I guess it was the cold weather?? These are Easton Aftermath arrows. I know not the best but not terrible either. Anyone else have this issue? Ideas how to fix the problem?
