I was planning on loading up some bullets last night, and opened up 3 different boxes of Nosler Accubonds and all of them look tarnished or burnt.  My questins are: anyone else ever had this problem?  Does it effect the accuracy of the bullet.  I chose to hold off on loading until I get some answers or some different bullets.  At any rate, they are stored in the garage, have never gotten wet, or anything spilled on them, and are a year or so old. 
  
Any info is appreciated.   
Thanks
