I was reading a treatise on "presumptive training", and the author was relating how a student in a class either did not fully seat the magazine, or inadvertantly activated the slide stop- I forget now which- and thinking he was out of burrets, did a combat reload. Because of that so-called presumptive training scar, he didn't do what he should have done; to wit, "tapped the magazine, rolled and racked a new round into the chamber."
So what is this "rolled"? I have an idea what it is, but I'd like to hear from someone who knows for sure.
