Oddly enough it appears that "Infallible Smokeless Powder" was later renamed "Unique" and was introduced to the market in 1898 along with some other Powders one of them being Bullseye.
"Page from a 1996 Reloader’s Guide, immediately after Hercules sold their smokeless powder business to Alliant.
The Infallible/Unique powder in this jar was actually manufactured at Laflin & Rand’s Pomton Lakes (Haskell, New Jersey) plant about 25 miles northeast of Kenvil, New Jersey. The jar still exists in 2007 and was moved to Alliant’s New River plant in Radford, Virginia. Originally, there were two of these jars, but one of them has not been seen in many years. The label on the front reads, “ Unique Smokeless Powder This powder was placed in water on
June 26, 1899.
Renewed: August 13, 1917
August 6, 1981 ”
If you read the article below it is fasinating, they have taken the powder from 1899, dried it out, loaded it and obtained excellent results.
