Greetings Blisters,
Looks like Military M2 rounds that have been drilled by someone. That it is a pretty big drill hole and there is a danger that the jacket could be left in the barrel if you fire them. The lead core will be exposed at the base, not like a earlier hollow point. The best option would be to pull the projectiles and dump the powder. The powder may or may not be something similar to the original Hodgdon surplus 4895. Have a good look inside the cases for any corrosion, common if the cartridges have been stored in too hot conditions. If all is well you can fire the primers in your .30-06 But remember to pour a jug full of boiling water through the barrel immediately afterwards. The primers are corrosive and normal cleaning will not remove the salt from the barrel. Rust will follow. The cases were made in the Des Moines Ordinance plant in 1942. There may be more info on the other side of the packet. The primer pockets will need to be reamed before re priming with standard large rifle primers. Annealing the case necks before reloading would be wise. I have used WW2 surplus .30-06 and Canadian .303 cases in the past with good results.
Regards Grandpamac.
