I recently inherited an ammo can of 30-06 ammo. To my surprise, it appeared that the whole can was M2 AP ammo. Headstamps on the first 100 rounds was DEN 44. Most of the ammo looked shootable, but I don't have a 30-06. So, I decided to pull the bullets and have them loaded in 308 cases in the future. After I pulled the the first 100 rounds from the cloth belt, the rest of the rounds don't have the black tips anymore. Headstamps on these newer rounds are WRA 52. These newer rounds have ball poweder instead of the stick like the older stuff. However......these bullets will stick to a magnet. This indicates to me that they are at least steel core....probably AP also. My question though....just exactly what bullets are these? They are shorter, FMJ, and about the same size/weight as standard 147g ball. Are these M61 AP bullets loaded into 30-06 cases? Did M61 AP even exist in 1952? Both bullets measure 0.307" diameter. Tell me what I've got here guys. I'm sure these newer bullets will load easier into 308 cases since they are shorter and won't cause the problems that the longer AP rounds cause when loading into the shorter 308 cases. See pics...
