This has happened to me twice with recent Winchester 16s in my Citori. The first time I was at Olin's club in East Alton, IL. I too it inside and they sent it off. I got $7 worth of "Winchester Bucks" in the mail. I don't think I'll be buying at Cheddites to reload with. Incedentally, I put WW209s in the Cheddite and Fiocchi hulls all of the time. They may not fit extremely tight, but I've never had one fall out either.
