Back about 1986-87 the Army started switching to the Beretta so they stopped buying 45 ACP ammo. Then they noticed that the slides were cracking on the Beretta.
I was running the AK NG Marksmanship and had a pistol team to support. We still used the M1911a, Match and Service Grade. Since the Army didn't have any 45 for out teams I used State Funds to buy Primers and Powder. We cast bullets and loaded 45 ammo on an old Dillion RL 1000. We were able to keep shooting 45s where other states went to 22 pistols.
Then the Army, having grounded the Beretta program until fixed, realized they needed pistol ammo and bought 45 Ammo from Israel.
Shortly our 45 ammo request were filled leaving me setting on thousands of Primers and a lot of powder.
In 1992 I retired and the person who relieved me had a heart attack when he did an inventory of the property book before signing for it. Seeing the supply of primers and powder started telling me it was illegal to reload military ammo. I tried to explain that there were rules against using Federal funds, but none against using state funds.
Didnt matter, he wanted the components gone. They were expendable items, not property book items so I decided to dispose of them.
I'm still doing that, The powder has been shot up but I still have several thousand CCI Large Pistol Primers from the mid 80s. They still shoot. A few years ago I loaded a batch of 45s using the old mid 1980 primers and new primers and ran them through a chronograph. I could not tell the difference.
What is does mean, since I have lots of brass, the old primers, and I cast bullets I only have to buy powder. I'm getting 45 powder for about $28 per lb. meaning it cost me $0.016 per round to shoot 45s. If I can shoot 45s for $0.80 cents a box of 50, I'm gonna use my old primers.
