[QUOTE="J E Custom, post: 1693366, member: 2736"] When I shot matches that required several hundred rounds a month, I bought powder in 8 pound containers and found that over a short period of time the powder degraded from the first moment it was opened to the last loading's because every time I re-opened the bulk container the humidity had an effect. so much so that I stop'ed buying bulk and went back to 1 pound containers. Each 1 pound container would load around 175 loads and that was enough to get me through the month most of the time. When I bought 1 pound cans with the same lot # I found no change from one can to the next because when I opened it for the first and last time I loaded all that It would. I use out of one can at a time and leave the others sealed to stay fresh. I have some rifles that take over 120 grains of powder, but I don,t shoot them more that 60 times a month. So I just prefer not to open a powder container more that once or twice in some cases. Again, this is just the best way I have found to buy and take care of my powder. If it is the same batch # it should be ok to mix, but many will read this to be ok to mix different lot numbers of the same powders and hear in lies my problem with saying it's ok. Keep in mind that Powder is manufactured and sealed with a certain moisture content. Once you open it that can change. (Especially on the gulf coast where humidity is normally between 70% to 98%). As to the mixing ease, I have worked in plants that mixed pellets to different percents that would take hours and special machines to get the samples to come out right in each sample even though they were added by %/weight in the beginning as sample were taken small samples had to show the same % to be considered mixed properly. Just pouring it back and forth several times realy don't mix it uni-formally. Just My Opinion J E CUSTOM [/QUOTE]
