Since my local BassPro only tapes one side of the primer case when they sell them by the 100ct sometimes they spill out. When this happens you never know about it until you get home. Thank god I noticed. So I bought Federal Champion small pistol primers which are yellow colored inside. I ended up with about (8) of the primers that are yellow with the red in the center. Can anyone help me out and tell me what I've won in the primer lotto I didn't want to enter? The majority of them are the yellow ones on the left. The 8 odd ones are the red ones on the right. They are the same size as the SP primers so I'm guessing either SP Magnum or Small Rifle. Thanks in advance.
