[QUOTE="J E Custom, post: 768912, member: 2736"] It would probably be ok, But I personaly would not mix different lot numbers or even the same lot numbers for several reasons= I would use out of one and leave the other cans sealed to last longer. The other reason is that you can never get them mixed uniformely and the results may vary shot to shot. When I run out of one can I seperate the next batch of loads to verify the velocity of the new can/lot of powder and then adjust the load volume accordingly. (It might only take 1/10th of a grain, or might not need any adjustments) but it does happen even with the same batch sometimes based on the age and number of times you opened the old can to humidity. It sounds like spliting hairs, but at long range everything effects the POI. I stoped buying bulk powder (8 pound+ kegs) after I found velocities falling the older the powder got and the more I opened it in the 90% humidity of south texas. Just my opinion J E CUSTOM [/QUOTE]
