So I am new to powder coating. I have looked for answers on here, and found them for most of my questions. However, I couldn't find something specific on a few. One of the ones I am most curious about is powder coating bullets for a 6.8 SPC. I have a mold that throws 107 to 109 grain hollow point bullet, plus a gas check. I plan on coating them, then sizing the gas check on them afterwards with a Lee bullet sizing die. My question is how much does it matter what alloy I use? Do I need a hard alloy, as I would with regular lubed cast lead bullets? Or can I use a softer alloy because leading isn't an issue because of the powder coating and gas check? I still have a bunch of 20:1 in the pot from casting handgun bullets, and I ran a batch of these that look very nice. I would love to try them in my 6.8 guns.
