I don’t see any rifling marks on it. Probably worth at least $100 on today’s ammo market. If only it were a primer the kid would be rich.

good point on the rifling.

I was going to guess "stray bullet" made its way into the package,

but now my money is on "FBI put it there" as part their insidious relentless ANTI-GUN program

( when they aren't busy shooting up Jason Aldean concerts in Vegas or supplying money to broder cartels to buy guns as in Fast and Furious, now they are putting bullets on snacks trying to change public opinion on gun ownership )

I don’t see any rifling marks on it.

That was the very first thing I noticed as well.

Glad I scrolled down a few comments and found yours so I wouldn't post redundant stuff.
