I purchased ammunition from a company out of state. I received the product 223, 55g fmj ammunition. I went to the range to fire it in my Sig AR. Well in my first magazine the gun completely blew up. I was injured and my friend sitting behind me was injured. My Sig a $1800 dollar gun was destroyed. I suffered severe bruising and minor cuts. My friend was hit in the face with shrapnel and if he was not wearing glasses would of lost his eye. I spoke with 4 other people on the Internet that also have similar experiences. I wanted to set up a Class Action Law Suit against the manufacturer. I believe they have a 8 million dollar product liability policy.
