This round came in a box with the information " DIST. BY : MARS EQUIPMENT CO.". Headstamp is "308 69 " on 12 , 6, o clock. Has a nickel plated primer, gmcs bullet jacked, no seals. Any ideas who made it? Thanks, Jan.
Your “308 69” cartridge was made by Amron of Waukesha, Wisconsin, U.S.A., a division of Gulf & Western Industries, Inc., for Centennial Arms. there is also a headstamp “308 1” with both being found sometimes in the same box. I don’t know the significance of the “1”.
Thank’s for the great info, now I have to look for an other headstamp too. Wishes, Jan.
