I have come across some Dupont Bulk powder that is likely 90 years old. I found a load for 22 Hornet in an older Lyman manual.

A minimum load of Dupont bulk is giving me 22 Long rifle velocities and incredible accuracy with the 37 grain powder coated NOE PP bullet.
The Chronograph shows velocities that are consistent with published data in the Lyman manual.

The burnt powder smells exactly like Dominion 22 WhizBang® ammo from the late 1950s. What memories that brings back.
