I started handloading in 1974.

In all that time I’ve ONLY had 1 (one) can (metal) to degrade and yield the
Red dust.

To the best of my ‘memory’ it was IMR 4831 in their yellow/white can.

NOTE- it was an OLD can of powder.

IMO powder properly stored lasts a LONG time.


** I have had one instance of ‘ neck weld ‘ so that can happen too.
