I’ve had hang fires and delayed ignition a few times. Needless pulling the trigger, hearing the click and thousand one, thousand two… bang is un-nerving.
Assuming the fire pin strike was not retarded, some powders are harder to ignite and more so at lower temps. It doesn’t have to be super cold, I’ve had loads that worked well in the 60’s give me a click, pause, bang in the 40’s.
