Ruger and Federal have been good to me. My wife was shooting one of my Ruger MK II pistols about a month ago. The gun kept stovepiping. It was recently cleaned so I knew it wasn't that it was dirty. The next thing I know the bolt ears pop off the gun and hit my wife in the cheek (she wasn't hurt, just startled). I have heard of this happening on some of the MK II's so I immediately called Ruger. They told me to send the complete bolt back.
I figured I'd call Federal as well and let them know what happened. I told them I didn't think the ammo was double charged but I wanted to be on the safe side. Federal sent UPS to pick up the remainder of the ammo from that box.
Ruger sent me a replacement bolt free of charge. The only thing was that they sent back a stripped bolt. I called them, they apologized and they sent out a pre-paid package and told me to send the stripped bolt back and they would send me back a complete bolt. It sucks to be without my favorite little bull barrel but mistakes happen, I'm not that upset about it, in the end they made it right.
Federal just called me on Monday about the ammo. They said they had fired off the rest of my box and had no problems. I told them again that I didn't think it was the ammo but I wanted to err on the side of caution and I would hate it if someone got hurt because I didn't speak up. The rep said that he was going to send me out a full box of ammo as a replacement, even though there weren't any problems with mine. He told me that it wasn't easy to find .22's anymore and they appreciated me sending my box of ammo in as a precaution to their customers. I thought that was pretty cool of them to do.
