LOL Dang, BTDT a few times, couple bags of TZ 77 marked 308, have no idea what that is, appears some sort of fmj bullet.
Probably stuff for the M-60
10-4, Thanks Buddy.
Thanks to everyone else too, have looked at M1's, see the Springfield and H&R versions, even some cool old M1 match rifles, this will be a fun exploration.
Also found around 1500 lake City 5.56 brass cases.
