Interesting concept, but *doubt* on how practical it would be on a battlefield. Far too much bulk vs. range for the payload, no matter the modern materials. I suppose if you were in an A-Team situation it might be workable as a surprise improvisation for one or two quick shots, if you already know how to build one with whatever modern materials were on hand. Would be fun for the backyard or pumpkin toss competition. I know some autist built one a few years back that he could lob cars with a good distance. Pretty sure it was over 100 yards, iirc. Under some bizarre use case that could be effective, and I think pumpkin toss events get out at the half mile or more range for smaller payloads.
