This is not exactly 'Accurate Shooting', but it is reloading related.
A while back I bought a reloading equipment lot from a guy, a Dillon 550, dies and a bunch of other stuff. Included in one of the boxes were four 1lb metal bottles of W231 and some really old CCI primers. From the conditioning of the packaging it is clear that these have not been stored in an ideal environment. The guy said everything had been in his garage for some time (in Houston, which is hot and humid).
The lot number of the powder (179E052B) apparently means it was manufactured in 1991 (or 1971, though that is the first year the metal bottle was introduced). The primers have a lot number of C19W and are marked as being manufactured by 'Omark Industries'. According to the interwebs this makes it likely they were manufactured in March 1974.
I did not have high hopes for either powder or primers looking at the state of the packaging but when I opened one of the bottles and removed the seal it had a nice 'woosh' sound indicating it was still properly sealed. The powder looks great, neutral smell. What really surprised me were the primers. The packaging is yellowed but the primers themselves look like they came off the line last week. Super shiny and the compound looks great.
I have used W231 (new manufacture) in the past for 9mm so I loaded up the following using the W231 from the old bottle:
11 count of Federal brass, 4.1gr W231, new manufacture Winchester SPP, 124gr RMR Nuke, 1.066 OAL
11 count of Federal brass, 4.1gr W231, the old CCI SPP, 124gr RMR Nuke, 1.066 OAL
Did one set with new primers in case the old ones would not go bang.
Took them to the range this morning and chronographed the velocities with a Garmin.
New primers + old powder - Avg 1064 fps, 5.2 SD
Old primers + old powder - Avg 1064.5, 7.6 SD
They all shot great, felt exactly the same and normal.
Attaching pictures of the powder bottle and primers. I thought it was interesting how well these components are working even though they have clearly not been stored in an ideal environment for at least parts of the time since they were manufactured.
