Zinc cast boolits long term effect in barrel wear?
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.
