I really thought this was a joke, until I tried it . It actually worked pretty darn well. I've only owned a shotgun for a week or two, but after a few tries, dropped a whole second, from 8 shells in 8 seconds to 8 in 7. And this was from Pinwheels, where I had to grab twice for each set of four. I'm now really curious how I'd do with one of those fancy FSLs.
I also noticed I can almost hold all 8 rounds at once in my monster hands. Is Load 8 just around the corner?
