Cleaning things out and found 15 rounds of these in 3 stripper clips
Military rounds.
Headstamp says 1951, FS, 79, and TOC with the O seeming to have some type. of halfmoon above it.
Bullet is FMJ, appears to be .30 caliber. Case is longer than my 7-08.
I can try to take and post pics.
TIA for any help.
