Greetings-
A friend of mine has around 1.5 lbs of Win 540, left over from when he reloaded shotshells, that he gave me to use up, (I reload all of his .38 SPL for him). I seem to remember reading somewhere that Win 540 and HS-6 were one in the same. Is this true? I am unable to find any 540 data in my manual, but there are tons of data for HS-6. I am looking for .44 MAG/SPL and .357 Mag/.38 SPL in particular. The powder is about 15 years old or so, but hasn't detiorated that I can tell; still it's time to use it up. I just need some data! Thanks much in advance.
