That price in 1952 was a bit expensive, although remember, there was not yet any quantity of surplus .30-06 Non-corrosive ammunition available anywhere. Virtually all American Military .30-06 known to civilians in 1952, right in the middle of the Korean War, was corrosive. I am surprised the government was selling any .30-06 at that time. Certainly there were shortages in availability of civilian ammunition, due to war needs, but not perhaps like the shortages during WWII. I cannot comment accurately on the price of 400.00 per 1000, as these days, other than a specimen for a collection, I would not even purchase corrosive .30-06 ammunition, so since I don’t ever look for it, I am not up on prices. It does seem high to me, though, for corrosive ammunition that was about 67 years old when you bought it. It probably still shoots o.k. - U.S. ammunition of the time was pretty good, but I think one could reload .30-06, even now, with a good jacketed bullet for 40.00 bucks a hundred or less. I suppose these days, the empty wood case has some collector value, and perhaps even a sample of the bandoleer, though.
