The first bullet, the Hornady, are the same as current production XTP-FP, just in an older style box.

The cast bullets are Lyman #358429, the Keith bullet. They could be home or commercially cast, no way to tell the difference. They just happen to be in a Hornady box.

Don't worry about trying to clean the Lead Oxide off of them. First it isn't worth the trouble, and second, it has lubricating properties of its' own! Instead just buy a bottle of Lee "Liquid Alox" and coat the bullets as-is following the instructions on the bottle.
