DashCaliber uses approx. BHN9 alloy, which works real well in most airguns.
My source of EPP/UG's offers them in whatever lead/tin alloy you choose. I order mine in about BHN5-6 lead, and unsized. The un-sized, near-pure lead EPP/UG's I shoot from the Mule Burro Corral are right at .456
His site is pretty new....he doesn't have most of the boolits he offers on there yet (including the EPP/UG's). Just give him a call and ask. All slugs come professionally packaged in styrofoam trays to protect the soft lead from the perils of shipping/handling.
Dirt cheap, too.

Mark Whyte carries them, too. He hates casting them, so he charges a bit more for them. Still not to bad, though.
