How to load coated cast bullets?

[bullseye308]

It really depends on your use. Are they just for targets and plinking or hunting/SD? How fast are you wanting them to go, are you looking for speed and expansion or just shooting small groups on paper?

I load mainly cast and powder coated that I cast and coat and all are loaded for accuracy only so whatever the speed is it is, but none are hot, usually midrange loads and I get no leading.

That would be entertaining, once. It's not hard to get above that limit with a fast-twist 223 barrel.

This is exactly why BHN 22 Linotype alloy became popular for casting. It can take the higher stress of high velocity without spinning apart. But it’s also brittle so there’s that.

I thought those became popular because insane rounds and pressure of 454, 460 and 500 s and w magnum. 50k psi pistol rounds because why not...

I blame J.D. Jones and Lee Jurass. SuperVel started a lot of loading trends that turned out to be less than ideal. But to be fair, the use of Linotype in rifle bullets has been around since the early 1900’s when the automated printing press came out and some clever handloaders figured out that used press castings could be used for making bullets. You can find references to the use of Linotype in Ideal manuals from the 1950’s as “Type metal,” 15-3-82 (antimony-tin-lead) alloy, recommended for use as-is for rifle bullets.

I started to hear about heat treating lead in a 454 thread and the hardness levels being discussed gave me pause. They were talking 30+ I has to google if that was even possible. Must shatter like glass.

This was a cool article I learned about it.
