Old olin plant winchester powder 1450LS|General Discussions & Questions|Forum|Winchester Collector

Hi all im new to this forum and would like to put this out there in the hope that someone may be able to help me with my quest to find some data on a powder that i picked up from a very old gentleman that loaded shotgun loads many years ago.

The powder i purchased from him is a winchester powder 1450LS i contacted hodgkins to try and source info on it and all they had was one load data on a shotgun load, and that it came from the Olin plant and that the plant had shut down in 1969, no other data that they have on there system.

I have been speaking with another gentleman 85 years old that has been in reloading for many years that has informed me that as it is a faster burning powder i can use it in my 38 special pistol rounds and 357 magnum.

I further was told without seeing any data that it is supposed to be the superseeeded powder of what once was available called 452AA powder. 

I understand this is a real stretch but i am hoping that maybe someone may have an old reloading book that they may be willing to share any data that they have. 

Thankyou so much and i hope someone may have some help for me.

Best regards Nathan
