weird failed to ejects

[powerboatr]

yesterday after a loooong hiatus from the range so my hand and arm could heal from the surgeons knife
my 9mm had issues at almost every round, except the expending of older pd rounds, those puppies ran perfect
sort of hate that i let em go
my 125 grn berrys with #7 powder kept jamming and getting empty casing stuck half ejected.

i was wondering if by some weird never before occurrence did my powder get effected by the sharp drop in temps and rise in humidity in the cold reloading room.
i have kept the heat off in there since before turkey day as i was recovering.
all my 45's and 380 rounds fired flawlessly,

these 9mm were also loaded using the last of my #7 powder in oct. and it was about 2 years old, but kept in its airtight container.

Is it possible that unconsciously trying to protect your post-surgery hand could have created some limp-wristing?

Try letting a different experienced shooter fire some of your rounds in your gun and see if they experience the same issues.
