And what it contains, in percentage of total weight or volume?

I know it's lead/antimony, but I'm sure it also has some tin, and I don't know in what proportions.

Just wondering.

I thought m193 was all lead except for the jacket.

I think you are correct. Never knew there was tin in a bullet till now.

It's probably just lead . Antimony and tin are added to harden lead up so when a non jacketed bullet is used, it does not lead up the bore. Once a jacket is added to the bullet it makes little sense to harden the lead inside.

Lead is per Mil-L 13283 Lead Antiomony 1.5% - weight is 32.0 grains plus or minus .3 grains. The rest of the weight is of course jacket. This is only off the top of my head I do have the full spec somewhere.

Antimony and tin are added to lead for a lot of reasons, not just hardness. They change the melting temperature and ductility of the metal too, so I think the antimony is just there to keep the bullet's core from deforming after it's been placed in the jacket.
