Just want to re iterate the importance of wearing eye protection while reloading. I had a .223 shell explode in my dillon 650 today. Ive loaded thousands and thousands of rounds over the past 5 years.. and never thought it could happen. It did and it sure scared the SH*T outa me. I was in the middle of a 100 round batch and I went up seated a new round and on the down stroke I just heard a incredibly loud pop and powder and debris hit my face. My ears were ringing, my face hurt, and I was shocked. I have no explanation on how it happened. Only thing i can think is that right after i put a primer in a round, charged the round, then on the down stroke the primer must have not been seated all the way in the round, or seated at an angle and pinched on something while the unit Indexed, causing it to go off. This theory though is still just about impossible wear your safety equipment!!
