Many years ago I read about naval battle enactments in the US using model warships fitted with BB firing guns. Built with balsa sides so the BB's could penetrate. Them some time later another article also in a US magazine about a group in Australia doing the same thing. Later still MMI published an article on a BB firing model of an Oto Melara 76mm QF . I wonder if they are still allowed to or has the practice been outlawed ? The US does not seem to be as much of a nanny state as Europe in general, but Oz Im not sure of.
Imagine the elf & safless finding that happening on a pond in the UK along with a sub firing explosive torpedos.............
Wonder where I got that idea from.............
