As for the cost of .22 LR I HAD to pick some up the other day and there were no bulk packs anywhere that I could find and hasn't been for a couple months now.
And I bought that store out of Blazzer long rifles with a brick and a half!
I payed $1.99 for a 50 count and was trying to remember what we paid for a similar 50 count box back in the 60's?
I am thinking .40 cents but cannot remember.
And the machines in that video looked like they may have been punching out cases back then also.
When watching the priming steps in the video I knew the cases were spun to get the compound into the rim, but I thought it was in a more fluid form.
