Iron Man - 5 to 10 shots? I think I'd have to put Peltors on top of my Peltors, under a welding helmet. Even at that, I'd probably be pleased to say that I had fired one or two rounds of full-power out of a barrel that short. Is there any such thing as a light load for that brute? Like Cowboy Action Cannon?
Aarond - re the ammo, that looks like a very fair price. Glad you posted the site.
