    Speed limit / rpm threshold for zinc

    Search hasn't given me any answers that I can find. I'm curious, since I can't seem to find wheel weights in my area anymore. I know Full Lead Taco has done testing, but has anyone gone down the rabbit hole to see what the limits are? Thanks fellas!

    History will record, with the greatest astonishment, that those who had the most to lose, did the least to prevent its happening.

    The problem with Liberals is not that they're ignorant, it's just that they know so much that isn't so.

    It's an interesting idea and I'm sure others will have insight, but I've always dumped my zinc...

    my concerns would be how my molds would last and then the bores when sending them.

    Just keeping the thread alive for ya, I'd be curious also.

    As Lead dries up, it is the future of casting.

    There are several youtube videos on it and they're pretty good.
    Word is, from the same Iron mold- they weigh about 60% what Lead does, you can push them up to jacketed speeds,
    and they don't need lube or powder coat.

    For a couple reasons, you'll need to set up for the stuff. Iron molds, and a hotter pot than our old electric ones made for Lead.
    There are a couple of old threads here that talk about it too.

    I haven't seen load data for it yet. But I think it's out there if ya dig around for it.

    OK People. Enough of this idle chit-chat.

    Perhaps a Google search for Zamac bullets would be in order.
    There is, also, an article in one of the (much!) older NRA books.
    Rights, and Privileges, are not synonymous. We have the Right to Bear Arms. As soon as the Government mandates firearm registration, and permiting, then that Right becomes a Privilege, and may be taken away at our Master's discretion.

    Be aware they will ricochet like crazy, and will pierce armor.
    The solid soft lead bullet is undoubtably the best and most satisfactory expanding bullet that has ever been designed. It invariably mushrooms perfectly, and never breaks up. With the metal base that is essential for velocities of 2000 f.s. and upwards to protect the naked base, these metal-based soft lead bullets are splendid.

    Forget everything you know about loading jacketed bullets. This is a whole new ball game!
