This is one I've never seen before and would like some help to ID it. My dad found a couple rounds of it in a box of misc old ammo he had in the closet and asked if I knew what it was. No idea so I measured it up and took a picture and figured someone here might know.
It's .243/6mm cal.
1.384 COL
.277 case diameter
.335 rim diameter
.049 rim thickness
1.131 case length
I have it pictured here next to a 22 mag for reference. Any ideas???
