A local shop has a lot of older bottles of powder but unfortunately he changed the price tags to todays prices. What did you load with that powder?
4227 is mainly for small capacity cases like .22 Hornet, and will work in .30 Carbine, also in various handgun Magnum loads, and also in some of the old large-caliber black powder rifle loads like .45-70.. I still have some cans of 4227 going back into the 1970s (when duPont made it), and there is nothing at all wrong with it.
