These have a red band versus Underwood's blue. Possibly a different maker?

They could be from slightly different molds, but the color is just the lube being used...

I will be trying both this and the Underwood when my barrel finally arrives. The thing is back ordered until May 30th.

Made a note in the original post to reflect the possibility of BE-86, I had mentioned that the powder had what looked like Power Pistol with some sort of identifier in the mix.
