Just wondering as hard as zinc is how much extra pressure and barrel ware it’s going to cause in the long run? I was trying to google the Brunelle hardness of it. What is it around 40? I guess that’s not super hard. If that’s what the hardness is i figured it’s gonna be like shooting a monolithic all copper solid bullet with zero expansion. I would assume getting the correct diameter is a must to keep pressures down and accuracy decent. Is the alloy hard enough to “ buldge” or wreck a barrel if to large of a boolit diameter? I don’t plan on ever casting any zinc boolits because I like expansion transfer with super soft lead bullets for hunting but I’m sure in states where lead is banned it would be a good cost efficient idea for somebody that has their hands on a lot of zinc wheel weights. I would think they probably would work like heavy shot and shotguns for turkey hunting.
