I’ve had rather strange stoppages from using too much spring. similar to yours, but not quite as dramatic. I’d not clean or lubricate it, and shoot a few hundred more from just that mag in an attempt to reproduce it. Mark the mag. Then I would return the rifle to stock and repeat. If it does it still, destroy the mag.
