I was given some WW II US milsurp 30-06. Most has DM 42 (Des Moines) headstamp with a few others. Shoots fine but some primers didn't go bang. 150 gr FMJ and a nominal 52 grs. of extruded powder. Any idea what powder was commonly used in these? I'm guessing IMR 4895 or 4064 or 4320, little short for 3031.
