Sounds like that the OP’s lot # is on the fast side for Unique.
There are fairly broad specifications in the final powder performance between “batches “ of gun powder within a brand. There used to be, and may still be a quantity of the original production of Unique and Bullseye kept stored in an underwater storage facility at the plant. It’s used for comparison testing and blending of different runs of powder to a consistent specification.
In 50yrs of reloading, I’ve seen several powders vary noticeably. Notably, Bullseye, and #231/HP38. Also HS-6 and Win540 due to lot to lot# variations.
I’ve also always called GreenDot “fast Unique”… I’m still working on a 8lb keg I was gifted over 10yrs ago. Been Using it in lieu of Unique all through the powder shortages… (but DO USE GREEN DOT data!) Old data to match the 1980’s production powder…
