Sccw3,
The green cloth carrier is called a bandolier. You said ten round clips? The M1 Garand has 8 round clips called
en bloc clips, in which the rounds are in a staggered column. As far as I know, they were always one clip to bandolier pouch. The Springfield '03 used straight clips called
stripper clips that held 5 rounds each, and two of those would fit easily in a bandolier. Now there are
10 round stripper clips for 7.62 NATO (.308 Winchester) for stripper clip loading of M14 magazines in situ. There were also 1
0 round stripper clips for the M1 Carbine which have a sort of flat shovel end that acts as a guide..
If you have the 5 round stripper clips and .30-06 ammunition (individual cartridges about 3 1/3 inches long), and the box says M1, then I would assume it is M1 Ball ammunition which was obsoleted in 1944, when all .30-06 ammunition was corrosively primed. On the other hand, if you have pairs of 10 round clips for the M1 Carbine (individual cartridges about 1 5/8 inches long), that ammunition was always made with non-corrosive primers from the git go, and was the first U.S. military to have non-corrosive primers.
