Is this good or bad?

Jams are so fun

I'm thinkin bad.
I inadvertently used a hollowpoint die to set round nosed bullets and had to pull them all back out and start over.

I'm thinking it's just cold

It is a bit nippy today

But its just from where the chamberd shell failed to extract and the next one was picked up and got jammed into the bottom of the chamber.

Have you tried re sizing the brass before dropping a bullet in it ??

Not good.
My BIL reloaded some cartridges for me once without resizing the casing. None of them would go in the chamber.
