30.06 Bullets

[Parashooter]

I was given 140 30.06 bullets . . .

I'm perplexed. The remainder of your text, and the pictures, indicate complete cartridges, not just bullets (projectiles). I'm sure you know the difference, therefore my confusion.

PPU .30/06 first appeared around here in the 1970's, under the "Hansen" brand. Don't assume non-standard flash holes until you have examined a fired case interior. Green stuff is sealant. The cartridge in the photos appears to reproduce the essential characteristics of USGI M2 ball, as did the Hansen cartridges I used years ago.

PPU .30/06 in this style is currently marketed under the "Prvi Partizan" brand. See example at Prvi Partizan M1 Garand Ammunition, .30-06 Springfield, FMJ, 150 Grain, 20 Rounds - 621640, .30-06 Springfield Ammo at Sportsman's Guide
