Info on old winchester powder

[elginrunner]

I was given some old winchester powder from a lady who's husband past away several years ago. It looks like shotgun powder and would make sense as I saw three sets of Mec reloaders. One pound (am at work and can't remeber) was in a metal can. It resembled a brake fluid can, white and light blue lable, 562 maybe?? Anyway the other was in a large coffee can. It seems he used to partner up and buy a keg with freinds. The powder looks good, light gray smallish flakes (looked like win 231) It has a hand written lable on it, but cant make it out.

Where can I find info on obsolete winchester powders??

Ok so I made it home. The 1 lb can is winchester 540. The 2lb can has 452. Was this a winchester powder?

452 was a Winchester powder slightly faster than 231 and pretty similar to HP38.
540 is fairly close to Herco speed wise.

You might try the manuals here:

HP 38 and 231 are exactly the same powder

the win 540 is HS6 and 452AA is 231 speed, there should be several hundred pages of data for pistol and shotgun

452AA is / was Winchester's fast 12ga trap powder. Somewhat like rod dot or 700x in speed.

I can absolutely confirm that W540 IS Hs-6. Lots of data for either one.

And 452 was indeed a 12-ga trap load powder similar to RedDot or 700X. You can use RedDot/700X data for less-than-maximum loads.

elginrunner get a Speer #11 manual there's 452AA data for handgun in it
