I loaded up at test batch of 21.5 gns of H110 with a 270 gn speer gold dot .44 mag using 15 year old Winchester Large Primers. My last load of these 10 years ago averaged 1620 fps using the same components, but this batch averaged only 1550.
The powder was new, it was the primers that were 15 years old. I'm figuring that they must have lost some of their zing over time. I'm off to get a new sleeve this week and will repost when I have results.
(I did check the chrony with other loads and it is fine)
