Soft Lead Gas-Checks

Crazy idea?

I got some lead ribbon rolls for melting and casting from a friend. It’s just around 1/2 inch wide and very thin, used for some kind of work in making composite truck panels.

It got me wondering – if gas-checks were made in one of various gas-check making tools, from thin enough lead sheet, and applied to a gas-check shank, would they work well enough to make effectively a Plain-Base boolit?  Reason I am keen on making this bizarre idea work, is some indoor clubs around my area are banning copper/alu checks, as they say the checks are somehow bouncing back and shredding the rubber splashback screens. (other clubs say this is NOT happening). But for the clubs that do ban, that would retire a lot of my gas-checked molds – unless I can make this work
