I ask that because I have never heard of, read about, or seen reference to a weak clip spraying rounds out, reducing the clip to an empty shell, thus dropping the clip to the bottom of the mag, letting the bolt slam onto the rifleman's hand- the bottom of the stack of bullets is retained by the follower, the top of the stack of bullets is reatined by the thumb, the sides are retained by the clip and the rifle's magazine.
That's not how I interpreted his statement. I was assuming that he meant (as I stated) that some of the spring temper had weakened, thus easing the grip on the cartridges contained within the clip, and letting the bolt chamber the first round with little or no effort when the loaded clip was inserted.
Although unlikely, that could theoretically catch the unwary thumb between the bolt and the receiver. ( I suppose.)
