The last time I saw anything like this was when I was in the Navy at a military training exercise with the Marines at Camp Pendleton, CA. It was night and there were multiple battalions of Seabees lined up at a firing line for as far as I would see. We had our M-16's on full-auto with mags filled with tracer ammo. When we were told to 'FIRE!', there was a solid arc of red from the firing line to the berm. Spectacular! I've never seen anything like it and I'm sure I never will again. This Henry shoot is the closest I've seen to it in the civilian world. Wish I could have been there. Enjoy!
