Just get some Super Hard Alloy, a bar of tin from Rotometals, mag shot, Marvelux and a 5 gallon bucket of water and you will be making bullets that are second to none. Trust me, there's nothing that will hit a coke can harder than an LBT WFN or LFN. I launched a soup can 30 yards with an LBT WLN and it blew the can to smithereens and it's accurate to boot. The gun though has to be capable and by there I see limits. But it is good to know what it can do and I'll tell you, there is nothing better than cast bullets moving at jacketed, or better, performance.
