I'm not going to try to 2nd guess anyone's theory at this point, especially after I completely missed the
whole jacket thing to begin with and I have guns also, incl an SKS.
However, when it comes to finding things w/a metal detector:
I found this at 3"-4" down and in solid ground, this dirt had not been disturbed in a very long time.
The ground is/was dry so that oxidation would have taken a while to materialize.
This site/area has absolutely no traffic, as it is in a very remote location in the Sierras.
But as I said, I'm not going to try to 2nd guess anyone else's theory.
Thanks, Brian
BTW I haven't measured it yet, but this would be one of the smallest diameter rounds, next to
a 22 I've ever seen.
