There are some butchers out that'll keep your meat separate, but they're in the minority.
I was eating some green chile pork stew this winter when I chomped on a piece of jacket and lead. The piece was about half the size of a BB. Now, here comes the weird part: This was a wild hog sow that I had shot in the neck with a .22 Hornet (NOT ADVISED-- target of opportunity), but the meat for this particular stew had come from the haunch. I had never found any other bits of bullet in the hog. That Winchester 45g bullet really blew pieces a long way!
Actually, what had happened, was my partner and I were walking along and saw the pigs at the end of a lane cut through the mesquite brush, and we entered the brush. From the brush screen, we moved up I shot at what I thought was a shoat (the distance was unknown, and I mis-estimated the range by a factor of 2 or 3X)). I heard a slight squeal, and it ran off into the tall grass, unhurt. I hurried up to the location it had been, and had to climb over a 5-strand barbed wire fence. Well, it
used to be a 5-strander!
My bullet had struck and broken the top steel barbed wire. I looked over the tall grass across another intersecting fence, and saw my pig had stopped about 80 yards out in a small clearing. I shot her, and she rolled over and did her impression of a pork chop.
Apparently, that first shot, that hit the strand of barbed wire, sent a fragment into her butt, which I ended up chomping down on most of a year later after pulling it out of the freezer. I had no idea any of it had hit her; she was about 20 yards behind the barbed wire fence.
