I just loaded 1000rds of 45 with Winchester 452AA. I don't think that has been made for 25 years. Shot great. I have 8 lbs of it.

Now for some old powder I have. I don't intend to shoot these.

1 can of Dupont 4227 Lot #26
1 can of Dupont 4320 Lot #30
1 can of Dupont Bulk Smokeless from the same era.

Anyone have a guess on how old these are. They have never been opened. I am guessing they are over 50yrs old.
