I was just gifted the remaining 7 lbs of a paper sac that started off as a 10 lb "lot" that was priced @ $12.50 ! I received it from the original purchaser and have bee assured that it has been stored cool and dry always! The powder itself looks like factory fresh and has little to no smell to it at all. From best recolections of the owner the powder would be at least 20-25 years old. My question to those that know is , Are there any additional precautions that I should be taking when starting load work up due to this powders age or shall I just begin with the standard 10% reduction and work my way up watching for presure signs. Thanks in advance.
