Pewter is an alloy of 95-99% tin and minor % of bismuth, antimony, lead, and 1% copper.

The real question is what will that 1% of copper do to your bullet melt alloy?  I don't know anyone that has tried it in bullet alloys, but it is know that any contamination of bullet melt with zinc is ruinous to the castability of the melt.

Thanks for the input ...when the whether  gets better I'll throw a small  chunk of pewter into a batch of bullets.
about 15 years back I tryed adding  some zink-- The corners of the lube grooves did  not fill out good - (kinda round looking -  like the Lee tumble lub ) .. I shot them anyway...nothing really bad happend....
Although the bullets were a little harder it was not a good trade off..

I have a scrap pile of cast off pewter items scavenged at yard sales and flea markets for just that purpose.  Never had a problem.  It's also good for inletting and decoration on tomahawk hafts, etc.

Good pewter is safe to use for food.
Cheap pewter has lead.

Maybe the stuff from China.  But, I don't think any western civilizations have used lead in pewter in about 200 years.  At least that is what I've heard.

From Wikapedia

Modern pewters must contain at least 90% tin and be alloyed with copper, antimony, or bismuth to be considered a pewter. Lead is no longer permitted to be an alloying element.  Older pewters with higher lead content are heavier, tarnish faster, and oxidation gives them a darker silver-grey color.

A typical European casting alloy would contain 94% tin, 1% copper, and 5% antimony. A European pewter sheet would contain 92% tin, 2% copper, and 6% antimony. Asian pewter, produced mostly in Malaysia, Singapore, and Thailand, contains a higher percentage of tin, usually 97.5% tin, 1% copper, and 1.5% antimony. This makes the alloy slightly softer.
